Question: Some close button is not available in ie11, under normal IE8 and other browsers.
I found that there are currently two reasons: One possible reason is that IE11 browser does not support some older methods of property, and one reason is the release code using a compression code, sometimes publish some events out of the code is not registered inside, probably compressed code and the original code is not the same. Like jquery-1.8.2.min.js and jquery-1.8.2.js these two files, compressed version of the code is missing some code, leading to the close button events can not be registered in, that is, the Close button does not take.
