An online text editor that I wrote that is compatible with IE and FF, similar to ewebeditor

How should I put it, I just finished the night, I must be very tired, but now I still have the strength to type these characters, it seems that I am not done yet.
Without further ado, I recently wrote an online editor, similar to ewebeditor. Of course it is not as powerful as others, but it has the basic functions and is compatible with IE and FF. I also spent a lot of effort on this. , let’s get the code out quickly

关键是demo.html和edit.js里的代码，core.js和advance.js里的代码是我为兼容浏览器写的，本想把它扩展成一个完善的框架的，因为时间有限，就没写下去了。

本编辑器还没有实现图片和文件的上传，因为需要服务器技术，所以我就没写了，可以交给读者慢慢研究。
我打算先将web放放了，开始专心于vc 的探究上，尽量能写出一个像样的程序出来，以后如果有时间我也会继续完善这个编辑器以及javascript兼容的框架。
恩，好好加油吧。
