I am facing this issue in IE9:

0x800a01b6 - Microsoft JScript runtime error: Object doesn't support property or method 'addEventListener'.

The line of code is:

l.addEventListener("DOMContentLoaded",I,!1),

To my knowledge jQuery 2.1.1 supports to IE9 and above. My application is in ASP.Net and want to upgrade jQuery 1.4 to 2.1.1. I tried by using below code right after the opening Head tag: 

<meta http-equiv="X-UA-Compatible" content="IE=IE9">

It did not work.

Does anyone know of a solution to resolve this issue or we can set this in config file too? Thanks in advance.

Per Specifying Legacy Document Modes, the value of the content attribute should be IE=9.

Note that if this is deployed across an Intranet, you may also need to change the compatibility settings on the client.

Hope this helps...

P.S. If setting content to IE=9 doesn't work, then something's getting in the way, e.g. syntax error, group policies, other settings. Merely changing the value of content to IE=edge won't make much of a difference.
