为什么jQuery给我一个错误'没有方法可排序'？

Question

I have a fiddle here

http://jsfiddle.net/WULsZ/1/

I load jQuery first and the code is pretty much straight from the sample so I'm puzzled as to why I'm getting an error

You have to include jQuery Core, then jQuery UI.

<script src="http://dl.dropbox.com/u/12337149/jquery.js"></script>
<script src="http://dl.dropbox.com/u/12337149/jquery-ui.js"></script>

If you include jQuery UI it will try to extend the jQuery Core, and if you include jQuery Core it will overwrite any previous instance of jQuery Core (including the extended jQuery UI code).

Here you go working demo : http://jsfiddle.net/WULsZ/7/

Hope this helps, cheers

Missing:

  <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.5/jquery.min.js"></script>
  <script src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8/jquery-ui.min.js"></script>

Jquery Code

$(function () {
    $("#sortable").sortable();
    $("#sortable").disableSelection();
});​
