Hi guys, i think this issue is still there, though it's fixed for a different line to the reported.

I'm having the same issue with this line
file:///android_asset/www/lib/ionic/js/ionic.bundle.js: Line 3177 : Uncaught TypeError: Cannot call method contains' of undefined

if (ele.classList.contains('button')) {

and as @revie mentioned, just need a small change to

if (ele.classList && ele.classList.contains('button')) {

not sure why was fixed for the other line as suggested and not for the reported one.

Guys i also get the error. In our ionic version 1.0.0 uranium. change as brayancastrop suggests can fix the issue.

Hi,

This error happens sometimes in our app using Ionic 1.0.1. It happens at the line 23 of the minified version. I looked at it and I found 2 possible candidates:

1- Line 3179 of ionic.bundle.js version 1.1.0

if (ele.classList.contains('button')) {  

2- Line 5046 of ionic.bundle.js version 1.1.0

var isModal = container.parentNode.classList.contains('modal');

Hope this helps!

Thanks @dpaloucva. In addition to your two, it looks like there's another one that is just like your #2, but on line 7189 in ionic.bundle.js v1.1.0:

var isModal = container.parentNode.classList.contains('modal');
