run a function when a user clicks on any list element
|
<p>This is probably a very common question, but I was unable to find an answer myself;</p>
<p>All my list elements call the function setQuery like this</p>
<pre><code>onClick="admin_stats.setQuery(this);"
</code></pre>
<p>rather than [hardcode] add this to every list element, is there a way to simply have it run when a list element is clicked?</p>
<p>I'm not very familiar with jQuery Live or binding/unbinding, but I think they would play a role here?</p>
<p>Before I reinvent a rather square-looking wheel I thought I might ask =)</p>
<p><hr>
edit: my list elements look like</p>
<pre><code><ul>
<li id="usersPerMonth" onClick="admin_stats.setQuery(this);">Users per Month</li>
<li id="statsByUser" onClick="admin_stats.setQuery(this);">Stats by User</li>
</ul>
</code></pre>
<p>the this.attr("id") is then used to look up what the actually SQL text looks like, from a json-style variable:</p>
<pre><code>queries : {
usersPerMonth : " ... some sql ...",
statsByUser : " ... some sql ...",
...
}
</code></pre>
<p>so that's why I have the divs named that way (and I'm open to design suggestions)</p>

<p>If i load the column and save it to a variable it looks of course like: <code>Michael, Myers</code> or <code>Michael Myers</code>.</p>

populate a textarea using javascript
|
<p>Basically I am using the SCEditor and want a button on forum posts or articles comments called "Quote" where it grabs the text from the message and pastes it into the textarea, i have this code:</p>
<pre><code><script type="text/javascript">
jQuery.noConflict(); //disable global $ for jQuery
jQuery(document).ready(function($){
$(function(){
$('#quote').click(function() {
$('textarea').sceditor('instance').insert("[quote=admin]Some text[/quote]");
});
});
});
</script>
</code></pre>
<p>Now that works, it will put "[quote=admin]Some text[/quote]" into the textarea. Problem is I need that to be dynamic somehow so i don't have to copy that code above every comment if that makes sense? So instead of this:</p>
<pre><code>insert("[quote=admin]Some text[/quote]");
</code></pre>
<p>That section would grab all the text from the box below it? Rather than me manually replacing the quoted bit with the text in the post.</p>
<p>So basically replace the quoted bit above with the contents from different divs based on clicking a Quote link?</p>

<p>Now after returning using PageMEthods i cannot iterate over the result to get the id and value of select options.</p>
<p>I cannot use JSON i have to use PageMethods only.</p>
<pre><code>ArrayList obj = new ArrayList();
var countries = EntityService.ServiceInstance.GetCountries();
foreach (var country in countries)

ListItemClass temp = new ListItemClass();
temp.ListItemText = country.country_name.ToString();
temp.ListItemValue = country.id.ToString();

Fastest way of getting a list of installed packages in an Android device
|
<p>I'm getting a list of packages installed in an Android devices very similar to the code here - <a href="http://www.androidsnippets.com/get-installed-applications-with-name-package-name-version-and-icon" rel="nofollow">http://www.androidsnippets.com/get-installed-applications-with-name-package-name-version-and-icon</a></p>
<p>The problem is that it takes quite a while to complete detection of all apps. I've discovered that the slow operations are those that call p.applicationInfo.loadLabel() and p.applicationInfo.loadIcon(). Once I comment those out and set them to dummy info, the detection is almost instantaneous.</p>
<p>Since I would still like to retrieve the app name and icon, I can't simply comment them out. Is there a faster way of retrieving this data?</p>
<p>Thanks.</p>

OutofMemory Exception (when cropping an Image)
|
<p>I am trying to crop an Image that coming from a byte array. Unlucky, I get the OutofMemory Exception in my cropImage function. this part show how I write it on a file.</p>
<pre><code>System.IO.MemoryStream ms = new System.IO.MemoryStream(strArr);
System.Drawing.Rectangle oRectangle = new System.Drawing.Rectangle();
oRectangle.X = 50;
oRectangle.Y = 100;
oRectangle.Height = 180;
oRectangle.Width = 240;
System.Drawing.Image oImage = System.Drawing.Image.FromStream(ms);
cropImage(oImage, oRectangle);
name = DateTime.Now.Ticks.ToString() + ".jpg";
System.IO.File.WriteAllBytes(context.Server.MapPath(name), strArr);
context.Response.Write("http://local.x.com/test/" + name);
</code></pre>
<p>and this part is my crop Image function which is obvious what it is doing..</p>
<pre><code>private static System.Drawing.Image cropImage(System.Drawing.Image img, System.Drawing.Rectangle cropArea)
{
System.Drawing.Bitmap bmpImage = new System.Drawing.Bitmap(img);
System.Drawing.Bitmap bmpCrop = bmpImage.Clone(cropArea,
bmpImage.PixelFormat);
return (System.Drawing.Image)(bmpCrop);
}
</code></pre>
<p>and this is how I construct my strArr</p>
<pre><code>System.IO.Stream str = context.Request.InputStream;
int strLen = Convert.ToInt32(str.Length);
byte[] strArr = new byte[strLen];
str.Read(strArr, 0, strLen);
string st = String.Concat(Array.ConvertAll(strArr, x => x.ToString("X2"))); // try 4

Trigger the change event of a textbox in jQuery
|
<p>I have an asp:TextBox with asp:RegularExpressionValidator to validate if it's a number. Obviously an onchange event will be attached to this textbox while rendering. Also I add a change event at $(document).ready to make some calculation when the value is changed.</p>
<pre><code><asp:TextBox id="myText" runat="server" />
<asp:regularexpressionvalidator id="myRev" ControlToValidate="myText" runat="server">*</asp:regularexpressionvalidator>
$(document).ready(function(){
$('[id$=myText]').bind('change',function(){
//do something
}).change(); //force the change event at the very beginning
});
</code></pre>
<p>My function will be executed later than the .net generated js because of the register time. But the asp.net js throws an error. I traced in the js:</p>
<pre><code> function ValidatorOnChange(event) {
...
}
</code></pre>
<p>and found that all of event.fromElement,event.toElement,event.srcElement are null which causes the exception. Did I do something wrong? Any solutions? Thanks.</p>
<p><strong>EDIT</strong></p>
<p>It's proved to be a MS bug, working fine in ASP.NET 4 vs2010.</p>

Javascript : Best way to declare functions to be used globally?
|
<p><strong>My javascript file is getting pretty big (3000+ lines) and I'm getting confused as to how to layout my file and delare functions so that they can called anywhere in the file.</strong></p>

var var1 , var2 ,var3
$(document).ready(function(){
//JQUERY STUFF
});
//ALL FUNCTIONS THAT NEED TO BE GLOBAL DECLARED HERE
function myFunction(){
//do some stuff here
}
</code></pre>

<p><strong>Could someone suggest the best way to layout a big js/jquery file with certain JS Functions, Objects and Variables available to be referenced anywhere in the file.</strong></p>
<p><strong>UPDATE:</strong></p>
<p>So to simplify it this correct (see my comments)?</p>
<pre><code>window.MainModule = (function($, win, doc, undefined) {//WHAT IS BEING PASSED IN HERE?

Set URL argument for Page_Load in some menu item click Javascript
|
<p>I am reimplementing an ASP.NET application with a main page (Call it "MyMainPage") which contains a user control. (Call it "MyNavControl") Within that user control is a menu control provided by a third party. Items added to this third party control have an "Href" property that is passed a URL. The code to create a menu subitem, contained within the codebehind of the .ascx for MyNavControl, goes something like this:</p>
<pre><code>ThirdParty.MenuItem subitem = new ThirdParty.MenuItem();
subitem.Href="MyMainPage.aspx?_page=PremiumCustomer&_title=Premium";
</code></pre>
<p>MyMainPage also contains a user control representing the bulk of the page body. Let's call that MainBodyControl.ascx. The Page_Load() for the main page sets up some session values which are used in the Page_Load() for MainBodyControl.</p>
<p>When the menu item on the main page is clicked, the main page's Page_Load() will be passed the arguments specified in the menu item control's "Href" value. So:</p>
<pre><code>protected void Page_Load(object sender, System.EventArgs e)
{
string sPageType = "";
if (this.Request[ "_page" ] != null) {
sPageType = this.Request[ "_page" ].ToString();
}
}
</code></pre>
<p>Here's my question: I'm replacing the third party controls with standard ASP.NET controls, so the current "Href" property mechanism can no longer be used. What would be the best way, in some JavaScript assigned to a menu item's click event, to set a new value for "_page" or "_title" above.</p>

Javascript .keyCode vs. .which?

<p>I thought this would be answered somewhere on SO, but I can't find it.</p>

if (e.keyCode === 13) {
e.preventDefault();
// do something
}

<p>But, I'm seeing examples that use .which instead of .keyCode. What's the difference? Is one more cross-browser friendly than the other?</p>

md5-encrypted string returns different from database than it is inserted

<p>So, I try to check if passwords match.</p>
<p>This is the encryption I use, once when the data is inserted in the database, once to check if the inserted password on the login field matches the one from the database:</p>
<pre><code> byte[] pass = Encoding.UTF8.GetBytes(password);
MD5 md5 = new MD5CryptoServiceProvider();
string newPass = Encoding.UTF8.GetString(md5.ComputeHash(pass));

<p>And the one encrypted from the login field:</p>
<pre><code>�]��$PL��fඇ�6�

Why isn't java.text.Normalizer available for my Android app?
|
<p>I'm developing an Android app and in Eclipse, <code>java.text.Normalizer</code> can't be imported. It's like Eclipse can't find it. I saw another SO question asking about <code>Normalizer</code> alternatives to Android apps that are < version 2.3. Is the class limited only to certain Android SDK versions?</p>

Set Value of a Dynamically Generated DropDown
|
<p>I have a dropdown menu that gets automatically populated. I need to set its selected value to a certain option whose ID is being passed in. This code seems to work with dropdowns that were created on page load:</p>
<pre><code> $('select[id$=DropDown1] option').each(function (index) {
if ($(this).val() == _PassedInValue) {
$(this).parent().val($(this).val())
}
})
</code></pre>
<p>But, it doesn't seem to work with dynamically generated content. Is there something I am missing or is there another way to approach this?</p>

looping through json data in JavaScript

<p>This is similar to <a href="http://stackoverflow.com/questions/2556476/ajax-coldfusion-cfc-json-hello-world">this question</a>, but I thought I'd reword it a bit differently in order to make myself more clear.

Abstract class with static methods. Is that correct?

<p><strong>Task</strong>: I want to use some methods for many classes. Methods are same, so there is no need to implement them for each class. In my case - I work with android SDK and I send http request to server.</p>

<pre><code>class abstract MethodsCarrier{
public static void method1(){ /*something*/ }
public static int method2(){ /*return something*/ }
}

<p>It works, there is no problems. But I'm not sure about making this class abstract. Is it's a right way at all?</p>

check if value changed upon change() trigger
|
<p>I noticed that change() can be triggered for a <code><select></code> even if the option was not changed.</p>
<p>See my <a href="http://jsfiddle.net/emMx6/" rel="nofollow">jsfiddle</a> example.</p>
<p>Changing the selection will change the text input displayed. However (and I do know it's a bit of stretch) if you:</p>
<ul>
<li>select the drop down by clicking on its label <code>Selection:</code> </li>
<li>press down on the keyboard (assuming <code>Show A</code> was selected) </li>
<li>then select <code>Show A</code> with the mouse pointer it will trigger change(). </li>
</ul>
<p>Is there an easy workaround for this (right now I'm thinking of using a variable to keep track what the last selection was upon change())?</p>
<p><strong>EDIT:</strong>
It seems it is a Chrome-specific problem. I was able to <em>fix</em> the problem by using a variable to keep track of what the last selected item was. I guess this a bug left for the jQuery/Chrome developers.</p>

Pass event to parent view?

<p>I have a layout which contains five TextView. When user clicks any of the five TextView, it will do the same thing: open another activity. So, the OnClickerListener behavior to the five TextView is the same.
Is it possible that I only add OnClickListerner to one view, e.g. to layout, so I don't have to add OnClickListerner to each of the five TextView?
Put it another way, if none of the children components receives CLICK event, will the CLICK event passed through to their parent, the layout? </p>

Parsing Line Breaks in PHP/JavaScript
|
<p>EDIT: Ok, thanks for your help guys. Using zerkms' suggestion, I have managed to get <code><br></code> tags inserted instead of carriage returns, so it is displayed properly on the page and doesn't break the javascript. The problem is now that when the user clicks on this text, it becomes a textarea and is therefore inline editable. However, the text string now has the tags displayed in it, rather than just having the editable text over multiple lines.</p>
<p>Any suggestions?</p>
<p>ORIGINAL QUESTION: I have a text area in my PHP application where users can enter notes in a project. Sometimes this is displayed on the page via PHP and sometimes it is displayed via javascript. The problem is, if the note is across multiple lines (i.e. the user presses enter while entering notes in the text area), it causes the JS to fail. It's fine when it's being done by the PHP.</p>
<p>The line of code in question is:</p>
<pre><code>var editnotes='<textarea class="desc_text" style="width:20em;" id="notes_editor"><?php print $notes; ?></textarea>';
</code></pre>
<p>So, if the note is over multiple lines, the PHP builds the pager as:</p>
<pre><code>var editnotes='<textarea class="desc_text" style="width:20em;" id="notes_editor">This is
a test note
over multiple lines
</textarea>';
</code></pre>
<p>And this obviously causes problems for the js. So my question is, what can I do to prevent this? As the code is being built by PHP before it even gets to the browser, I'm thinking that the best approach may be to parse it in the PHP so that the output is something more like this:</p>
<pre><code>var editnotes='<textarea class="desc_text" style="width:20em;" id="notes_editor">This is<br/>a test note<br/>over multiple lines<br/></textarea>';
</code></pre>
<p>Will this work? How would I do it?</p>
<p>Thanks</p>

checkbox filtering system
|
<p>I came across this page at <a href="http://www.walmart.com/browse/Computers/Desktop-Computers/_/N-96fg?browsein=true&catNavId=3951&ic=48_0&ref=%20428236" rel="nofollow">walmart.com</a> and on the left side of the page is a checkbox filtering system that is done on the client side. When you check the price checkbox selection it filters out the brands and disables enables/disables them etc.</p>
<p>When i had a look at the source code the checkboxes have no values and when i tried to find the <code>REFINEMENT.clicked</code> event I couldn't find it when I downloaded the page. It's a very big page with lots of code and would prob take a long time to go through it.</p>
<p>I was wondering how could I implement this filtering system in jquery for the client side. You could use a array that stores values but how would i know which properties the filters have as each page would show different filters (other than price range) based upon the product type.</p>
<p>If someone could point me in the right direction or give an example as to what to do that would help.</p>

Better alternatives to know whether a control is valid in javascript?
|
<p>I want to know whether a control is valid or not in javascript. Is there a direct client side API available in Asp.Net which can tell me whether a control is valid or not?</p>
<p>Eg. If I have 2 validators attached to a textbox, I need a function that can tell me whether the textbox is valid or not. If even 1 validator is not valid then it should return false.</p>
<p>I can't seem to find a function that can give me this. Here is a little helper that I wrote which does the job but is inefficient:</p>
<pre><code>function isControlValid(control) {
for (i = 0; i < Page_Validators.length; i++) {
var validator = Page_Validators[i];
var controlId = validator.controltovalidate;
if ($(control).attr('id') == controlId && validator.isvalid == false) {
return false;
}
}
return true;
}
</code></pre>

<p>Basically when you hold down any of the buttons with the class of <code>block_delete</code> for more than 1 second, the <code>OpenLoader()</code> should run. I googled and looked around on here and then made this, it kind of works:</p>
<pre><code>var functionDeleteBlockDia = function() {
$(".block_delete").mouseup(function (){
event.preventDefault();
});
$(".block_delete").mousedown(function (){
setTimeout(function(){
OpenLoader();
}, 1000);
});
}
</code></pre>
<p>The problem I'm having is that on mouseup the <code>OpenLoader();</code> dies, I tried to unbind mouseup even though there's no function attached to it, I tried to attach <code>event.preventDefault();</code> on it as you can see above, but it still didn't work. </p>

Getting mouse events to function on dynamically loaded elements
|
<p>I have a simple mouseover event that I am trying to work on elements that are loaded with ajax. For example I have a div that when you mouseover hide/show another div. When I load these divs through ajax they no longer work. For example :</p>
<pre><code><div class="block">
<div class="something">MOUSEOVER</div>
<div class="else" style="display: none" >HI</div>
</div>
$(document).ready(function(){
//using on hoping to catch the mouse events
$('.block').on('mouseenter',function(){
$(this).children('.else').fadeIn('fast');
});
$('.block').on('mouseleave',function(){
$(this).children('.else').fadeOut('fast');
});
});
</code></pre>
<p>This works fine straight up like <a href="http://jsfiddle.net/RwZWP/" rel="nofollow">this</a> : </p>
<p>But when I load those elements from another page :</p>
<pre><code>$j('#trigger').load( url + " .block");
</code></pre>
<p>The mouse events are no longer recognized. I thought this is what <code>live</code>, <code>on</code>, <code>delegate</code> were for. Can someone help me figure this out please.</p>

Accessing files stored in emulated storage
|
<p>I currently have an application that downloads files from a server and by default they are stored under /storage/emulated/0/ . I set it up so they download to a folder called "data". The files successfully download and unzip to /storage/emulated/0/data/unzipped , however, when I try to load an html file, stored under the data folder, into a webview, I get an error saying the file can't be found. I double checked the file path of the html file using Astro File Manager and was able to verify I have the right file path. Here is the statement I use to load the html file into the webview.</p>
<pre><code>wb.loadUrl(Environment.getExternalStorageDirectory()
+ "/data/unzipped/output.html");
</code></pre>
<p>I have tried it with and without the .html extension and still no luck. Any ideas? Are there are restrictions on accessing the emulated storage?</p>

Prevent ddl from triggering unsaved changes warning while still executing OnSelectedIndexChanged event
|
<p>I'm using this jquery code to detect unsaved changes and warn users before they navigate away.</p>
<pre><code> var _changesMade = false;
$(document).ready(function () {
$('form').bind($.browser.msie ? 'propertychange' : 'change', function () {
_changesMade = true;
});
$(window).bind('beforeunload', function () {
if (_changesMade)
return 'There are unsaved changes which will be lost if you continue.';
});
});
</code></pre>
<p>It works fine except on a page where I have a cascading dropdownlist. I added this code to the asp:DropDownList control</p>
<pre><code>onChange = "_changesMade=false; return false;"
</code></pre>
<p>and it stops the warning, but it also stops the OnSelectedIndexChanged server code from executing, so now the second drop down is not being populated with the correct data. How can I prevent the popup and still execute the server code when the dropdownlist is changed?</p>

hide or show large number of elements using jquery or javascript
|
<p>I have a situation in a web application, where based on certain conditions, I have to hide or show large number of div elements, numbers ranging from say <strong>500</strong> to <strong>98000</strong></p>
<p>.</p>
<p>What I am doing is I am applying a common class on all the div elements and then iterating the whole set of elements to check whether or not they are fitting in the circumstances and hence are shown or hide.</p>
<p>This logic works fine when the numbers are say in the range of <em>500</em> to <em>10000</em>, but above this range, it is taking quiet some good amount of time to display the result.</p>
<p>I am afraid for really large numbers, this logic may result in some browsers getting hanged.</p>
<p>So, what could be a better approach to handle the above mentioned situation, in most of the browsers </p>

Making smarter jQuery code
|
<p>I was wondering if anyone has any idea on how I could rewrite this simple jquery code to be more efficient. It's of course working fine now but I imagine adding say 10 more items would make the code really big. I thought maybe I could add the classes to arrays and use some kind of loop? Not sure if that's the right approach though.</p>
<p>Here it is on jsfiddle:
<a href="http://jsfiddle.net/QVS9X/42/" rel="nofollow">http://jsfiddle.net/QVS9X/42/</a></p>
<p>and here's a sample of it:
JS:</p>
<pre><code>$(".image1").mouseout(function() {
$(".default").show();
$(".cat1").hide();
}).mouseover(function() {
$(".default").hide();
$(".cat1").show();
});
$(".image2").mouseout(function() {
$(".default").show();
$(".cat2").hide();
}).mouseover(function() {
$(".default").hide();
$(".cat2").show();
});
</code></pre>
<p>HTML:</p>
<pre><code><div class="image1 image">
<p>Hover for cat 1</p>
</div>
<div class="image2 image">
<p>Hover for cat 2</p>
</div>
<div class="image3 image">
<p>Hover for cat 3</p>
</div>
<div class="default">
<p>Default Text</p>
</div>
<div id="cats">
<p class="cat1">Category 1 text</p>

Beginning Android Programming - Building a short Quiz
|
<p>Okay, so I'm writing my first Android app and am basically stuck. The app is a short 4 question quiz with two choices per question. This creates 16 possible results, which I've created descriptions for. I want the app to display the description corresponding to the user's responses on each of the questions after the 4th question is answered. </p>
<p>Right now I am storing the values in a string, which is supposed to build upon the previous string answer, after each question. So the first answer is t1, the second answer is t2, and so on. Here is the code for the second question:</p>
<pre><code>public class Question2 extends Question1 implements OnClickListener
{
private Button b1;
private Button b2;
public String t2;
public TextView text2;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.question2);
b1=(Button)findViewById(R.id.gamma);
b2=(Button)findViewById(R.id.delta);
b1.setOnClickListener(this);
b2.setOnClickListener(this);
text2 = (TextView)findViewById(R.id.TextView02);
}
public void onClick(View v) {
Intent a = new Intent(this, Question3.class);
if(v == b1)
{
t2= t1+"gamma";
text2.setText(t2);
startActivity(a);
}
if(v == b2)
{
t2= t1+"delta";
text2.setText(t2);
startActivity(a);
}
}
}
</code></pre>
<p>My problem is that the strings won't hold the values I assign them in the previous question. I have a textview that briefly displays the values returned by the question's answer string (t2 for Question2) and it displays nullalpha or nullbeta, depending on the user's response. </p>
<p>How do I retain the t1's previously assigned value into Question2 so I can add to it? For instance, if t1 = "alpha" from Question1, and the user selects button b1 in Question2 how do I make t2 actually equal "alphagamma" instead of "nullgamma"? Is this even possible with strings?</p>
<p>Any answers and suggestions are much appreciated.</p>

Best way to write a polling capable application
|
<p>I'm trying to build a basic application which will have 2 separate components which are:<br>
1. Continually poll an external process and store the results within a DB<br>
2. Grab the results from the DB and display it in a webpage</p>
<p>I'm looking to do this in .Net so I would normally say to do the first component in a Windows Service and the second in ASP.net with a relational dbms like sql server.</p>
<p>The problem with this is that i want to use webhosting to deploy this and they don't tend to allow Windows Services (unless you pay a fortune). So is it feasible to do the polling component in a seperate asp.net page, or maybe create a spawning worker thread within a single asp.net page that will do the polling for me?</p>
<p>Any opinions/input appreciated.<br>
Thanks :)</p>

How do I make jQuery modify only one div, instead of all divs of the same class?
|
<p>Each page of my site has 10 (almost) identical divs, varying only in the text within. When a certain part of a div is clicked, I want a different part of that div to be modified.</p>
<p>I'm using this code:</p>
<pre><code>$(document).ready(function(){
$(".notLogged img").mouseover(function(){
$(this).parent()>$("span").html("You must be logged in to vote.");
})
})
</code></pre>
<p>I thought this would work as follows: For all <code>img</code> elements within a "notLogged" classed div, a mouseover would cause a different part of that div to change.</p>
<p>However, that's not what happens. Whenever that mouseover event is triggered, <em>all</em> divs with the "notLogged" class are modified.</p>
<p><strong>How can I modify this code so only the div in which the mouseover originated is modified?</strong></p>

alert($("#show"+arr[i]).text())
});
}
</code></pre>
<p>But it doesn't work. I debug this code and find that this code <code>alert($("#show"+arr[i]).text())</code></p>
<p>only run when I click the <code>a</code> element . and when I click <code>a</code> . the variable <code>i</code> is <code>3</code> already.</p>
<p>So what should I do?</p>

Why use .on() for adding event instead of directly adding event?

</blockquote>
<p>From API:</p>
<p>.on() : Attach an event handler function for one or more events to the selected elements.</p>
<p>Example code:</p>
<pre><code>$("#dataTable tbody tr").on("click", function(event){
alert($(this).text());
});
</code></pre>
<p>We can just write something like: </p>
<pre><code>$("#dataTable tbody tr").click(function() {
alert($this).text();
});
</code></pre>
<p>Why bother wrapping the event inside .on() ? </p>
<p>Thanks. </p>
