50,379 | 50,380 | How to change the value of textbox when form is submitted? | <p>I have a form which has fields pre-filled with a default value, like this:</p>
<pre><code><input type=text name=first value="First Name" class="unfilled" />
</code></pre>
<p>When the textbox is clicked, the class <code>unfilled</code> is removed from the textbox, and the textbox is made blank so the user can type in his/her own info.</p>
<p>The problem is that when the form is submitted, its getting submitted with these default values, which is messing up the server side validation. How can I do it so that when the form is submitted, all the fields which have a default value are made blank, so the server side validation would throw the error: 'Please fill in this field'?</p>
<p>I'm trying the following code which isn't working:</p>
<pre><code>$("#myForm").submit(function()
{
$(".unfilled").val('');
}
);
</code></pre>
<p>This does make the fields blank, but the server still receives them with their previous default values.</p>

1,959,645 | 1,959,646 | Scrolling div by the #id, what am I doing wrong? | <p>I'm programming a message board for my site. Every message gets an id by auto increment in the database. The messages on the board are under "li id=#" tags where the "li" gets the id from the database. I've tried to create scrolling function via javascript so that down and up arrows would move across whole messages.</p>
<p>This is what I've got so far:</p>
<pre><code>down.node.onclick = function() { // down arrow
var msgs = document.getElementById("kommentit"); // the <ul> element
var a = new Array();
if (msgs.hasChildNodes()) {
var children = msgs.childNodes;
for (var i = 0; i < children.length; i++) {
if (msgs.childNodes[i].tagName == "LI") {
a.push(msgs.childNodes[i].id); // array with the id's
}
}
}
for (var i = 0; i < a.length; i++) { // this is what goes wrong
parent.location.href = '#' + 'a[i + 1]';
}
</code></pre>
<p>So while the array gets the right values the actual function doesn't work. With this code I get .../index.php#[a + 1] as my url when I click.</p>
<p>If I use ''+a[i + 1]+'' the page refreshes through the whole array until it settles with #undefined.</p>
<p>The id's are in format "id-xx" so is that the problem? I tried splitting the id by using msgs.childNodes[i].id.split("id-") but if I do this I get ",xx" as my values in the array.</p>

1,987,225 | 1,987,226 | How to Set Relative Position for Dialog Box when Page Becomes longer (Scroll bars are activated)? | <p>Have a web app which consists of a form and have it set up to launch a dialog box containing information next to the subject label text field.
Everytime, someone fills out the form and clicks on submit, the form's message body (from the text area of the form) is displayed on top and the
form is displayed underneath it. Before, I had it set up as fixed (x,y) for the dialog box to appear next to the subject label. But, now, when
the page becomes longer, the dialog box doesn't appear next to my subject label text field. It is displayed a lot lower.</p>
<p>Here's the code to find the position:</p>
<pre><code>// Finds the position and adds 40px to the left axis.
function findPosition(obj) {
var curleft = curtop = 0;
if (obj.offsetParent) {
do {
curleft += obj.offsetLeft;
curtop += obj.offsetTop;
} while (obj = obj.offsetParent);
curleft += 42;
// alert ('[' + curleft + ', ' + curtop + ']');
return [curleft,curtop];
}
}
</code></pre>
<p>Here's the code that calls this function to display a dialog box at a specific place:</p>
<pre><code>function displayDialog() {
var subjectLabel = document.getElementById("myform.subjectLabel");
$("#myDialog").dialog({
open: function(event, ui) {
jQuery('.ui-dialog-titlebar-close')
.removeClass("ui-dialog-titlebar-close")
.html('<span padding-right = "16px;">Close</span>');
},
hide: true,
draggable: false,
position: findPosition(subjectLabel),
closeOnEscape: false
});
}
</code></pre>
<p>How can I set it so my findPosition() calculation doesn't miscalculate when the page is too long (when scroll bars are needed)?</p>
<p>Is there a way to set the relative positioning to always have the dialog appear 40px right of the subject label?</p>

<p>I'm currently converting this from coldfusion. In the previous application, I had multiple table layouts for displaying different kinds of information, for example, phone number instead of userid. (although, working with a lot more columns, I shortened it for posting). In coldfusion I would just wrap each table in a <code><cfif></code> tag controlled by a variable that said which view to use. I am unaware how to get multiple data displays into a single page controlled by a variable, like I was before. Mostly because, it appears that most of my logic is done in the code behind files, so I don't understand how to get those changes across in the .aspx, or how to manipulate them from the code behind file. </p>

<p>And the admin page there would be a button to release the lock and redirect to another page. Or if the user forgets using the Session_End() in the global.asax file and having an autorefresh. But how would this stop someone from pressing the browsers backbutton and bypassing this?</p>
<p>Or should I try to make sure the configuration files haven’t been changed before writing to them? But how would I save the state for this page. Should I like save the files modification time in Session state and if they diff just abort the save action? </p>
<p>So the question is: how should I protect my application from concurrency issues while not disturbing the normal users?</p>

<p>I have an image that is of dimensions 1174px x 660px within a container of dimensions 1174px x 375px. The image's height is cutoff and only 375 pixels worth of the image's height is displayed as I set overflow hidden on the container.</p>
<p>I have created a JavaScript function that takes this image (1174x660) and vertically centers it in its container (1174x 375) so that the center of the image is at the center of the container.</p>
<pre><code>function allFeaturesImagesResize () {
var allFeatures = function () {
var image = $('.all-features article img'),

container_center = .5 * container_height,

image.css('position','relative').css('bottom', center);
}
$(function () {
$(window).resize(function () {
allFeatures();

Client has an Android phone that is not activated to use cellular services and his office does not have wifi. He wants me to write him a simple customized contact list that he can view the names and the phone numbers of people(already completed). However, he wants a Desktop Client (done in Java) where he can update the contacts, as he is a bit older and prefers using a standard sized keyboard instead of the slider keyboard on his phone.(this is completed as well).</p>
<p>I need to complete a class for the app that will read a file on the PC's local hard drive and update the contacts file on the SD card.</p>
<p><strong>Options:</strong><br>
As far as I can tell, my only option in this case would be to use the USB port from the phone. I will have the desktop client write the contacts file to the SD card on the Android Device.</p>
<p><strong>Question:</strong><br>
Can I use the USBManager class to have the app:<br>
1. Look for xml contact file on PC.<br>
2. Read the file on the PC and update the file on the SD card.</p>

</code></pre>
<p>First I had the problem that when the event was raised the checkbox wasn't keeping the checked property value. This is still strange because nowhere in the application we set the EnableViewState to false and by default it should be true. Well this behavior was fixed by puting EnableViewState="true".</p>
<p>So now, I have a checkbox that when I first load the page, wworks correctly. I check the box, the event is raised Checked property valu is good and the method is executed. Postback completes and renders the page. I check the box back to false, the event is not triggered and the page is reloaded with the previous data but the Checked Property stays at true.</p>
<p>So after the first postback I seem to loose behavior of event and ViewState.</p>
<p>We suspect the fact that we move dynamically the controls in the page (See answer <a href="http://stackoverflow.com/questions/375093/asp-net-possible-to-create-a-usercontrol-that-include-inside-markup-content">here</a>)</p>

<p>So i have written onclick = document.formName.submit(); Now it is triggering the same page and i am able to write the code. I am not able to differentiate which checkbox is checked.</p>
<p>I don't want to use the procedure of:- calling javascript and then storing the value of the checkbox in a variable and making this variable as invisible. </p>
<p>I would like to write something like document.formName.submit('checkbox1'). So that i should be able to handle the value of this or i dont know.</p>

1,696,269 | 1,696,270 | Dynamically build combo/radio options | <p>I will have a product page that could have up to 20 different SKUs on a single page, but all have the same master record. The master record has aload of flags in it saying if it has height/depth/width/length. </p>
<p>I am trying to dynamically generate selectable options on a product page and build an 'option map' or function so that all the other options are filtered on the client side and they end up with the correct SKU.</p>
<p>I'm not sure which way to approach this as i've only just started learning javascript, normally I would just use asp controls and I could easily postback and update controls but i'm trying to make it as nice to use as possible.</p>
<p>Could I register a javascript function on page load with all the product options in an array and then rebind the combos/radios onChanged? I was thinking I could Dynamically generate the combos I need in c# code behind based on the master flags and link them to my new javascript function?</p>
<p>I'm happy to go away and research stuff I just want to make sure there's not a better way of doing it (or if this will even work).</p>

746,224 | 746,225 | Credential Caching issue | <p>I have a static helper method that I wrap around SMTPClient to send email.</p>
<p>I am storing the SMTP authentication in the web.config -> in the default location that System.Net namespace objects look for.</p>
<p>I am passing the credentials to the SMTPClient, because I want to run my password decryption on the password before the SMTPClient uses this.</p>
<p>The issue that I'm encountering here is - when I run this once, the password is stored somehwere as "decrypted" somehow in the cache. When I try and run this method a second time in the same session, I get an error, because it's trying to decrypt a password that was already decrypte the first time it was ran. Any ideas?</p>
<pre><code> public static void SendEmail(MailMessage mailMessage)
{
SmtpClient smtpClient = new SmtpClient();
NetworkCredential nc = new NetworkCredential();
nc = (NetworkCredential)smtpClient.Credentials;
nc.Password = Tools.Decrypt(nc.Password);
smtpClient.Credentials = nc;
smtpClient.Send(mailMessage);

3,028,143 | 3,028,144 | Possible to toggle/animate between two sizes using jQuery? | <p>Basically I have a small div that is initially styled to 60x60. I have created click event that animates the expansion of the div:</p>

$(this).animate(
{
width: "350px",
height: "300px"
}, 500);

<p>I would like to reverse this animation if someone clicks the div again. Is there anyway to toggle between the original size and the expanded size (still using the animate function) with each click? </p>
<p>I found the toggleClass function but I don't think this will work with animiate.</p>
