we are facing dhtmlxgrid loading issue in IE11. dhtmlxcommon.js throwing this error saying like
“Object or property doesn’t support this method getElementsByTagName” . we are using jquery 1.4.2 in our code.
Please suggest us.
I think it has nothing to do with your version of jquery.
getElementsByTagName is broken with IE11 
You will need to update your librairies. Please check on this forum. I think there is a patch with fixed librairies.
Sorry, if I’m not a big help!
Brgds.
