If the version is EXTJS2.2, it should be reported at the ext-all.js233 line: the object does not support the "createContextualFragment" attribute or method, this is a BUG of extjs2.2, it should have no IE9 at that time, only later versions solve this problem. I have encountered this problem in the past two days. According to the online check, many people have encountered this problem.

I have encountered this problem in the past two days. According to the online query, many people have encountered the same problem. The solution is as follows:

Add the following code before the line where the ext-all.js reports an error:

If (typeof Range! = "Undefined ")&&! Range. prototype. createContextualFragment)
{
Range. prototype. createContextualFragment = function (html)
{
Var frag = document. createDocumentFragment (),
P = document. createElement ("p ");
Frag. appendChild (p );
P. outerHTML = html;
Return frag;
};

I tried to solve the problem. However, EXTJS seems to have many problems in IE9. If it is set to the browser compatibility mode, many problems can be solved. I hope everyone can take out the problems they encountered in IE9, discuss them together, and find a solution.
