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。

暂无自己写的兼容ie和ff的在线文本编辑器类似ewebeditor的评论...
稳了!魔兽国服回归的3条重磅消息!官宣时间再确认!
昨天有一位朋友在大神群里分享,自己亚服账号被封号之后居然弹出了国服的封号信息对话框。
这里面让他访问的是一个国服的战网网址,com.cn和后面的zh都非常明白地表明这就是国服战网。
而他在复制这个网址并且进行登录之后,确实是网易的网址,也就是我们熟悉的停服之后国服发布的暴雪游戏产品运营到期开放退款的说明。这是一件比较奇怪的事情,因为以前都没有出现这样的情况,现在突然提示跳转到国服战网的网址,是不是说明了简体中文客户端已经开始进行更新了呢?
