IE 9 Script error SCRIPT438: Object doesn't support property or method 'addEventListener'

Asked 21/11, 2011 at 21:38 Answered 4/10, 2016 at 22:10

I have a jQuery popup window that works in Firefox.

However, I am getting the following error message on line 1 of my html page:

SCRIPT438: Object doesn't support property or method 'addEventListener' popup_1.html, line 1 character 1

The only code I have in line 1 is:

<html>

When I run the IE9 debugger, I am getting an error on something called

script block(1)

But I am not using any javascript named "script block" is this an Internet Explorer add on or something?

Looks like I had to add the html 5 doctype:

<!DOCTYPE html>

I got this error in IE10. The issue was the browser was running in compatibillity mode. Hit F12 and turn it off. The error is gone.

I also set Document Mode to Standards – Tradein 3/9, 2015 at 17:11

Adding the following tag solved this issue for me:

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

This error usually happens because IE creates JS variables for every HTML node and it conflicts with jQuery & other JS things you're adding.

Make sure you have the following tags:

Both these tags tell IE to render the page using Edge, the latest renderer.
