Widgets Cannot Be Initialized in Internet Explorer Compatibility Mode


Product Progress® Kendo UI® for jQuery
Kendo Version 2017.2.621


Kendo UI widgets cannot be initialized in the Internet Explorer Compatibility Mode and an error is thrown.


Kendo UI widgets provide WAI-ARIA support, which means that some ARIA-specific attributes are added to the HTML element.

When a widget tries to add a WAI-ARIA attribute using the attr jQuery method, which in turn calls the Element.setAttribute method, the Internet Explorer in Compatibility mode will raise a JavaScript error.

This issue affects all Kendo UI widgets that add WAI-ARIA attributes to HTML elements.

Error Message

SCRIPT3: Member not found (in Internet Explorer 10+ in Compatibility Mode)


The problem is reported to Microsoft on and a jQuery bug report is submitted.

To handle this issue, use any of the following solutions:

  • Force the Internet Explorer to use the Edge mode:

    <meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1" />
  • Path jQuery. For more information about the possible path, refer to the jQuery bug report.
