Replace UpdatePanel with JQuery

问题:

I'm using UpdatePanel to asynchronously call a button click event in a page that calls a method in another class which writes out an XML file on the output. Is there a way to do this with JQuery instead of UpdatePanel?

回答1:

Use jQuery to handle the click event. Then call a page method in the code-behind using this technique. From there you can write the XML file or do whatever else you want.

回答2:

A simple alternative way to using jQuery to do ajax without the update panel is to use a build in mechanism of ASP.NET called 'page methods'. By decorating a static method in the page behind with [WebMethod] the web site will have a generated javascript function you can call using PageMethods.MethodName(param1, param2). You will still need to include a ScriptManager control and enable page methods like this:

<asp:ScriptManager ID="theScriptManager" runat="server"
    EnablePageMethods="true" /> 

For more information you can search for 'Page Methods ASP.NET AJAX'.

Hope this helps

To call a button click event in jquery you can do this...

$("#MyButtonID").click();

Where the button html looks like this...

<input type="button" id="MyButtonID" value="Press Me" />
