I tried to find all possible clean action in my IDE, and nothing changed.
Then, I download all script and css files from your demo website and use them instead, it works! But I Still want to know which one breaks the function, so switch them back to mine one by one. Finally I found it IS the jquery.jqGrid.min.js file! It’s really strange that the one from GitHub doesn’t work..
Big thanks for you! It’s really a big surprise that I can get response so instant from here!
