ExtJS does not identify IE11

Question

I have a lot of problems when ExtJS (v4.0.7) does not identify IE11.

In this case occurs many UI bugs under IE11 browser.

I couldn't use "flax: 1" for grid columns and other layout stuff.

Answer 1

I found the solution which brilliantly fixed all my problems under IE11.

So, I have the HTML where I include next files:

• < script src="lib/ext-4.0.7/ext-all.js">..........................# ExtJS lib
• < script src="app/util/overrides/lib-overrides.js">.....# ExtJS overrides
• < script src="app/main.js">.........................................# Application

In lib-overrides.js I insert the code which fix IE11:

Ext.apply(Ext, ((a = navigator.userAgent) && /Trident/.test(a) && /rv:11/.test(a)) ? {isIE:true, isIE11:true, ieVersion: 11} : {});
