JQuery not working.

Question

I am trying to implement JQuery in my web page but i am not been able to implement it successfully.

I have a master page

where i added one script for menu bar that is already using jquery hosted by Google

This is coded in master page itself

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.0/jquery.min.js"&gt;&lt;/script&gt;

Now i want to implement a Jquery to set the css visibility property to true or false. into my content page of same master page.

    <script type="text/javascript">
            $(document).ready(function(){  
                $("#lnkAddMore").click(function(){
                 alert();
                  }
                  );
            });
        </script>

This html control is under my UpdatePanel. I dont know why it is not working ? I am using this control under UpdatePanel.

<input type="button" id="lnkAddMore" value="Add More" />

I tried to use it outside my update panel it is running successfully but not in UpdatePanel

I think there is a problem using it with an UpdatePanel

HERE IS MY PAGE SOURCE

   <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.0/jquery.min.js"&gt;&lt;/script&gt; 


    <link href="../../Css/Domain.css" rel="stylesheet" type="text/css" /> 
    <script type="text/javascript"> 
        $(document).ready(function(){  
            $("#lnkAddMore").click(function(){alert();$('#h').hide(100);});
            $('#h').show(100);
        });
    </script> 


       <asp:ScriptManager ID="ScriptManager1" runat="server">
        </asp:ScriptManager>
        <asp:UpdatePanel ID="UpdatePanel1" runat="server">
        <ContentTemplate>
            <div id="divDomain" runat="server">
<asp:gridview/>
                <div style="text-align:right;">
                    <input type="button" id="lnkAddMore" value="Add More" />
                </div>
            </div>

        </ContentTemplate>
    </asp:UpdatePanel>

Answer 1

Do you really have nested <script> tags or was it a typo?

<script type="text/javascript">

<script type="text/javascript">

If that's not a typo, then that's probably the issue.

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.0/jquery.min.js"&gt;&lt;/script&gt;
<script type="text/javascript">
    $(document).ready(function() {  
        $('#ddmenu > li').bind('mouseover', ddmenu_open)
        $('#ddmenu > li').bind('mouseout',  ddmenu_timer)
    });

    $(document).bind('click', ddmenu_close); // do you really want to close on any click?
</script>

Answer 2

When you're loading code in under an UpdatePanel, try not wrapping it in $(document).ready();. Ready isn't fired on document for AJAX events.

Answer 3

Check that the ID of your button isn't actually getting changed to something like

ctl00_ContentPlaceHolder1_lnkAddMore

since it's residing in a content placeholder for the master page.

If it is, you'd have to adjust your JQuery.

I have used two approaches with jQuery and UpdatePanels.

The first is this: http://stackoverflow.com/questions/256195/jquery-document-ready-and-updatepanels/256253#256253

The other approach I found on Rick Strahl's blog (http://www.west-wind.com/Weblog/posts/154797.aspx) Which is to do something like this in the code behind:

ScriptManager.RegisterClientScriptBlock(this, typeof(Page), "alertScript", 
    @" $(document).ready(function(){  
            $("#lnkAddMore").click(function(){
             alert();
              }
              );
        });", true);

Check this out for another example: http://stackoverflow.com/questions/844004/problem-with-scriptmanager-registerclientscriptblock-and-jquery-in-internet-explo/844714#844714

Also have a look at jQuery's live() event subscriber.
