method 1:
If we directly use the css display: none to hide its copyright information, there will be problems, that is, after you operate 10 times, the editor will automatically replace a textarea.
So, we can not display: none to hide, and replaced by position: absolute; top: -10000px; opacity: 0; with the above set of css is possible, but needs its own debugging css input about the content of the above to fill gaps space.
Method 2:
To use display: none to hide, and then go and change the code, you can simply change a character. Editor with search var c = new Image, and then see the following
!0 === f.ul
Simply change ===! == enough.
As there are no other restrictions, they did not know, anyway, using the above limit becomes 10 times textarea are gone.
