自己写的兼容ie和ff的在线文本编辑器类似ewebeditor
更新时间:2012年12月12日 10:59:15 投稿:whsnow
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,需要的朋友可以参考下
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。
