The uiquery plugin bgiframe (version 2.1.1) causes the following java script error in Internet Explorer 9:
jquery.bgiframe.js, line 94 character 5
In the plugin code for bgiframe version 2.1.1 was doing a regex search for "6.0" but it needs to search for "MSIE 6.0". Tillito has found the correct source.
In the bgiframe code look for:
if($.browser.msie&&/6.0/.test(navigator.userAgent)
Change to:
if($.browser.msie && /msie 6\.0/i.test(navigator.userAgent)
OR just get the source here: https://github.com/brandonaaron/bgiframe/blob/master/jquery.bgiframe.js
After some more research I found a solution myself on the bgiframe site:
I downloaded version 2.1.3-pre at
https://github.com/brandonaaron/bgiframe/blob/master/jquery.bgiframe.js
and this solved the problem.
Add below tag after head tag
<meta http-equiv="X-UA-Compatible" content="IE=8" />
var parent = document.createElement("div");
parent.innerHTML = html;
this.insertBefore( parent, this.firstChild );
