jQuery: undefined

[Tomasz M.Lipiński]

Hi,

I'm a lamer for sure :-) but:
there is a following declaration on my .aspx page:

  <telerik:RadScriptManager ID="RadScriptManager1" runat="server" EnablePageMethods="true">
    <Scripts>
....
      <asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.jQuery.js">
      </asp:ScriptReference>
....
    </Scripts>
  </telerik:RadScriptManager>

But when I try to do something with jQuery, the jQuery object is undefined. What should I do to be able to use it?

Regards
Tomasz

Hello Tomasz M.Lipiński,

The first step, when including the jQuery script library that is embedded in Telerik.Web.UI, is to add a ScriptReference pointing to Core.js as we use a slightly customized version of jQuery which depends on Core.js. We have not modified the implementation of jQuery in any way. We have just appended a few more lines of JavaScript at the end of the file in order to avoid any version conflict and to include a few useful jQuery plugins.

After including the jQuery file you can start using it. However, the jQuery object is available as $telerik.$ instead of the default $ or jQuery aliases. This is so to avoid compatibility issues with applications which already use (other versions of) jQuery. That is why, in order to use the default aliases, you need to include another script reference:

<telerik:RadScriptManager runat="server" ID="RadScriptManager1" >
   <Scripts>
       <asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.Core.js" />
       <asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.jQuery.js" />
        <asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.jQueryInclude.js" />
   </Scripts>
</telerik:RadScriptManager>

Additional information is available in the Using jQuery topic of our documentation - http://www.telerik.com/help/aspnet-ajax/using-jquery.html.
