FCKeditor cannot pop up a dialog box in ie9 (pop-up layer compatibility problem)

Therefore, whether you want to paste content in the page editor or upload images or other things that require pop-up window operations, you can only refresh the page if you want to perform other operations. The reason is that IE 9 does not support var $ = Document. getelementbyid.
The solution can be as follows:
Open this file, FCKeditor/Editor/JS/fckeditorcode_ie.js, and find the method in line 38th: fcktools. registerdollarfunction
Change the original CopyCodeThe Code is as follows: fcktools.registerdollarfunction?function(a?a.=a.doc ument. getelementbyid ;};

The modification method is as follows:Copy codeThe Code is as follows: fcktools. registerdollarfunction = function (a) {A. $ = function (v) {return a.doc ument. getelementbyid (v );}};

I personally did the experiment and the results were satisfactory ..

In other words, FCKeditor has retired with honor. Instead, its ckeditor is more powerful and the loading speed is faster! If you prefer the image upload function of FCKeditor, you can use ckfinder to complete it.
