View 8 RepliesFor the moment, I'm trying to learning some basic jQuery. But when I try to create a small thing with jQuery, it doesn't work. First, I thought that it was my standard browser Chrome that was not supported.
When I tried to render it in IE and Firefox, the result stays the same.
What do I wrong ?
Here u can find the code (ps I'm working with a master page, but I don't think that this has any influence)
<asp:Content ID="Content1" ContentPlaceHolderID="HeadContent" runat="server">
<script src="Scripts/jquery-1.4.1.js" type="text/javascript"></script>
<script type="text/javascript">
$(document).ready(function () {
$("#orderedlist").addClass("tof");
$("#orderedlist > li").addClass("groen");

I've been thinking about starting to work with AJAX because it seems easy to use things like the update panel. I also want to use a modal popup. I know that JQuery has some really stuff and I want to use it eventually. I want to take the path of least resistance for now though.
there seems to be some overlap in what the two technologies offer. There are similar things offered in both of them. I think I have to use AJAX for the partial page updates though.
How is the learning curve for JQuery compared to AJAX?
to directly get all elements in a form who contains a non html attribute ?
<input .... customAttribute="validateMe">
So I could find all input elements that will require validation.And use this in a loop to add validation to the input's found :
$('input').attr("customAttribute").val() == "validateMe"
I could also write every validation for each object separately, I have only a few elements who uses a required validation but it would be nice that I could do this in one shot instead of repeating the $("input").rules("add .....

View 2 RepliesI am using jQuery for custom sorting my <ul><li> list.But I have a problem. I can sort and move those <li>-s but problem is I don't know how to update database with new order integers.Example of html ul li:

This is an example of my li element.. I have id=43, thats Id of picture in database.I use this javascript for trying to somehow make array and read that id into array:

Problem is I don't know exactly what am I doing wrong, because my event doesn't fire, when I press "update button.. Update button fires "update" function on click:

I hope someone will try to explain.Do codebehind and html needs to be in the same document? Can I use ascx and use "update" button there, to fire aspx methode?
I have 2 update panels where the server-side button (in a jQuery accordion) in the first update panel should update the second update panel.When the button is clicked, jQuery hides the accordion and displays a results div. This all works fine client side to be fair to IE. The server-side onclick event does not fire though in IE. In Firefox it does! The first update panel is displayed below, here the "btnGenerateReport" event should fire server side.
[Code]....
To add confusion ... if I comment out '$accordion.toggle($effect);' lines then the second update panel does get updated.I'm not sure what other information I can give here. I'm stumped as to why this works with Firefox and not IE.
one juvenile question , i am having a asp.net intranet application which is using jquery, instead of ref jquery to every page, i decided it to put it on the master page inside the script manager scriptReference tag. note not all pages of my application requires jquery, so is it a wise thing to do, or it will affect the performance,
View 2 RepliesIf I use jQuery AJAX to call a specific ASP.NET page method how to have that method return a value back to the AJAX method that called it?
Update
My situation is I have an existing web application with many existing methods. I would like to be able to use jQuery to execute some of these methods and then update the UI with the results. My mandate is to stay away from ASP.NET AJAX and stick with jQuery. Management is concerned about continued development and support with ASP.NET AJAX from Microsoft. I agree with them.
On my page I have textbox in which user enters value. When 3 values are entered the autocomplete panel shows.In the panel the names and surnames of all available people are shown bassed on the value user enters. Bellow each name and surname is picture of each "candidate". However images are stored on another server (using https "protection") and some people don't have picture.
onerror="this.onerror=null;this.src='../Pics/Errors/NoPic.jpg'"
into <img> tags in Web Handler.
I have a nested master page. A parent master page, a child master page and a content page whose master page is the child master page. I have a reference to jQuery in the parent master page in the head section.<script type="text/javascript" src='<%#ResolveUrl("~/includes/jquery-1.4.2.min.js") %>' ></script> & Page.Header.DataBind(); in the OnLoad event.
I am using jQuery in all the pages including the master pages. However I am getting "Error: $().ready is not a function" in the content page. If I include jQuery reference in the content page it works. Question: If the reference to jQuery is in the master page head section, why aren't the content pages able to use jQuery? When I do view source, the script tag with jQuery is there and it works. The master pages and content page are merged during rendering and sent to the browser as a single html page so I am not sure when master pages are used, jQuery references break.
UPDATE:
When I changed '$.ready(function()' to 'jQuery(document).ready(function($)' it worked! I am not loading any other javascript libraries and I am not using MS Ajax.
We have a site that is public facing, let's say it's http://www.example.com. When the SSL is implemented, [URL], I can no longer access the jQuery 1.4.3 file on my own server. Furthermore, after a tweak to the security setting, I was able to get past the 'Access is Denied' error, but the first call was null.I understand there is a problem with different protocols actually being within the scope of the cross-domain problem? Is that true? And if so, will this now require JSONP?

I'm finding it next to impossible setting up a slideshow given the constraints I have. I could do it easily using a listview control except listview controls don't automatically page themselves! Is it possible to use jquery to create a play/pause button to auto page through the listview control, making it a slide show?
View 1 RepliesI have a link button in a repeater control. the li element is drag and droppable using jquery. when the page loads the the link button works perfectly, the jquery that is attached and the server side code both execute. when I perform a drag and drop then click on the link button it doesnt not fire. when i click it a second time it does fire. If i perform 2 or drag and drops in a row the link button doesnt fire a as many drag adn drops as i before it will fire. for example if if perform 3 drag and drops then it will take about 3 click before the events are fired.
