Is there any easy way to make a Ajax call in a Webpart?

开发者_开发技巧

I have a Webpart with a button, and I want that when the user pushes the button, it executes a server function without reloading the page. And then, if all is ok, execute a callback function. I thought that the best way is with a AJAX call.

But when I've looked for how to do it I only get some complicated tutorials that I don't really understand (and most are from old versions of Sharepoint). Any help? What is the best way to start? Thanks

Have you tried using jQuery with a content editor web part? I've done this before and it's rather easy. Here is a step by step for how I do it.

Download jQuery.
Upload jQuery to SiteAssets in Sharepoint.
Upload coded file (see below) with AJAX calls.
Point to coded file via Content Editor Web Part.
It should work!

Here is a default way something should work.

<html>
  <head>
    <script src="<point to jquery file>"></script>
    <script type="text/javascript">
      $(document).ready(function(){
        $('#main').load('<RELATIVE URL TO SERVER PAGE>');
      });
    </script>
  </head>
  <body>
    <div id="main"></div>
  </body>
</html>

If possible I would go for a Visual Web Part in Visual Studio. You basically create a .NET user control. It saves you a lot of manual control definitions etc.

If in SharePoint2007 you might want to take a look at the "Smartpart". It has ajax support and some great tutorials on how to use it.
