怎么说呢，刚包完夜吧，应该很累了，但现在仍有力气敲打着这些字符，看来我还没有到此为止啊。
废话少说，最近写了个在线的编辑器，类似ewebeditor那样的，当然没有人家那么强大，但是基本功能都有，而且还是兼容ie和ff的，为此我也花了不少功夫，还是赶紧把代码祭出来吧

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。

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。
