KindEditor编辑器在ASP.NET中的使用

KindEditor编辑器在ASP.NET中的使用

最近做的项目中都有用到富文本编辑器，一直在寻找最后用的富文本编辑器，之前用过CKEditor，也用过UEditor，这次打算用 一下KindEditor。

[b]KindEditor简介[/b]：

KindEditor是一套开源的HTML可视化编辑器，主要用于让用户在网站上获得所见即所得编辑效果，兼容IE、Firefox、Chrome、Safari、Opera等主流浏览器。KindEditor使用JavaScript编写，可以无缝的于Java、.NET、PHP、ASP等程序接合。 KindEditor非常适合在CMS、商城、论坛、博客、Wiki、电子邮件等互联网应用上使用，2006年7月首次发布2.0以来，KindEditor依靠出色的用户体验和领先的技术不断扩大编辑器市场占有率，目前在国内已经成为最受欢迎的编辑器之一。[来自百度百科]

将开发包导入到项目
将下载的开发包中不需要的删掉，只保留项目需要的文件，我的项目是ASP.NET项目，所引用的开发包资源如下图所示
