Can I use IE edge with old versions of ExtJS?

I want to use

<meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1">

Will it cause any problems?

Solution

  • I highly suggest you to not use old versions of JavaScript libraries. They usually have bugs that have been fixed in newer versions.

    Chances are good that a very new browser version (especially of IE) results in some issues that are usually quickly fixed in a new version of the library, but if you stay with an ancient version.. well, your scripts might break!
