jQuery not working with IE 11

Object doesn't support property or method 'addEventListener'

'jQuery' is undefined 

I'm using IE 11,



and jquery-ui-1.11.0.custom/jquery-ui.js (theme roller)

Before 2.1.1, i was using 1.11.1 with chrome (worked fine)

I have tried this fix but it did not work for me


The problem was caused because the page was an intranet site, & IE had compatibility mode set to default for this. IE11 does support addEventListener()

As Arnaud suggested in a comment to the original post, you should put this in your html header:

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

I don't want any cred for this. I just want to make it more visible for anyone else that come here.

For me the issue turned out to be I was using es6's right arrow functions => as opposed to function ().

Replacing => with function () resolved for me.

I had assumed it was a jQuery issue.

Thanks @Arnaud & @Conny for highlighting this answer. This really helped me. I would like to add one more thing here is, adding this line <meta http-equiv="x-ua-compatible" content="IE=edge"> just after the title in tag prior to all meta tags is must for to work as it overrides the compatibility mode of IE.

Place this meta tag after head tag

<meta http-equiv="x-ua-compatible" content="IE=edge">

Adding the "x_ua_compatible" tag to the page didn't work for me. Instead I added it as an HTTP Respone Header via IIS and that worked fine.

In IIS Manager select the site then open HTTP Response Headers and click Add:

The site didn't need restarting, but I did need to Ctrl+F5 to force the page to reload.
