I should be tired after the night package, but I still have the strength to beat these characters. It seems that I have not reached this point yet.
To put it bluntly, I recently wrote an online editor, which is similar to ewebeditor. Of course, it is not as powerful as other people, but has basic skills and is compatible with ie and ff, I have also spent a lot of effort on this, so let's sacrifice the code.

The keys are demo.html and edit. the code in js, core. js and advance. I wrote the code in js for a compatible browser. I wanted to extend it into a perfect framework. Because of the limited time, I didn't write it anymore.

This editor has not yet implemented the upload of images and files, because the server technology is required, so I did not write it, you can give it to the reader for further research.
I plan to release the web first, and start to focus on vc ++'s exploration, and try to write a decent program, in the future, I will continue to improve this editor and the javascript-compatible framework.
Well, come on.
