Solution 1

Thanks for your answers. The problem was that the library was included multiple times in different files.

Solution 2

View the page's HTML to see if there are script references to other versions of jquery in the page. If an older version is loaded after the correct version then invalid methods will throw exceptions.

Solution 3

The dialog method is from the jQuery UI library. It looks like you are using a custom version of jQuery UI, which may not include dialog.

You can customize which modules to include in jQuery UI here: http://jqueryui.com/download

I need to create a dialog with jQuery in a pretty big project. In some places, this project uses jquery wich version is different from the one I use recent for my window.

My code looks like this:

on ascx page

<html>
<head>
  <link type="text/css" href="css/jquery-ui-1.8.22.custom.css" rel="stylesheet" />
  <script type="text/javascript" src="js/jquery-1.7.2.min.js"></script>
  <script type="text/javascript" src="js/jquery-ui-1.8.22.custom.min.js"></script>
  <script type="text/javascript" src="js/myjQueryCode.js"></script>
</head>
<body>
</body>
</html>

in myjQueryCode.js file

$(document).ready(function() {
    $("#dialog-form").dialog({
        autoOpen: false,
        height: 440,
        width: 500,
        modal: true,
        closeOnEscape: false
    });
});

At runtime, I get the error:

Microsoft JScript runtime error: Object doesn't support property or method 'dialog'

When I use this code in a separate asp.net project, it works well.

Does the other project use the same jquery-ui-1.8.custom.min.js file?

You can download the full jQuery UI library at the link in the answer, or Google can host it for you: <script type="text/javacsript" src="ajax.googleapis.com/ajax/libs/jqueryui/1.8.21/jquery-ui‌.min.js">

Yes, the file in the other project is exactly the same. Thank you for the link, but when I include it, result is the same error.

Could it be some kind of conflict in jQuery files?
