AFAIK mutation observers are not available yet in IE. Chrome, Safari, Firefox have their implementations and its working its way through the standardization process. I'm wondering if anyone (preferably MS employee) knows the story with IE, or might give me a pointer to an article I missed.

• 2 You're wondering why IE is behind others with implementing something? – Ian Commented Dec 18, 2012 at 21:03
• 1 sadly, caniuse. is silent on the topic. – John Dvorak Commented Dec 18, 2012 at 21:04
• Thanks Jan. Ian, I'm not wondering why they're behind, I'm wondering how long they'll be behind, and if they already offer some faster alternative to binding to the DOM mutation events. – ccunni Commented Dec 31, 2012 at 23:23

IE 11 supports MutationObservers natively. For IE 9-10 you can use this polyfill: https://github./Polymer/MutationObservers

There's a recent article on Windows 8 app development which uses onpropertychange to handle DOM mutation.

Example 4: Handle onpropertychange for ARIA-selected property to detect programmatic change of tab selection.

    tabElement.attachEvent("onpropertychange", selectionChanged);

    function selectionChanged(event) 
     {
     if (event.propertyName === "aria-selected")
       {
       if (event.srcElement.getAttribute("aria-selected") === "true") 
         {
         // execute code to load the content that corresponds with the selected tab element 
         } 
       else 
         {
         // execute code for deselected tab, if needed
         }
       }
     }

For patibility with IE9-10, https://github./webmodules/mutation-observer exposes the native MutationObserver API provided by the browser, or a polyfill based on mutation events.
