kindeditor-4.1.10 结合 Asp.Net MVC 添加图片功能
KindEditor是一套开源的HTML可视化编辑器，现在我要结合Asp.Net MVC4 上传图片功能，做相应的配置和修改，
其实网上也有人写过类似的文章了，我写出来是以防以后使用的时候出现这样的问题，所以收集起来做参考之用，
如果有人遇到这样的问题，可以和我一起交流，qq号在我博客上已经贴出来了。
下面就开始贴出我的源代码：
js:
var keditor;
var koption = {
allowFileManager: true, //是否可以浏览上传文件
allowUpload: true, //是否可以上传
fileManagerJson: '/KindEditor/ProcessRequest', //浏览文件方法
uploadJson: '/KindEditor/UploadImage'//上传文件方法(注意这两个路径)
};
KindEditor.ready(function (k) {
keditor = k.create('#content-js', koption);
prettyPrint();
});
function btn_submit() {
var lables = '';
var title = $("#txt_title").val();
if (title.length == 0 || keditor.isEmpty()) {
alert("标题或内容为空！");
return false;
}
$("input[name=lable]:checked").each(function () {
lables += $(this).val() + ',';
}); ;
zwobj.url = "/Manage/AddArticle";
zwobj.data = { title: title,
content: encodeURI(keditor.html()),
lables: lables.substr(0, lables.length - 1)
};
ajaxData();
return true;
}

总结：
要注意
var koption = {
allowFileManager: true, //是否可以浏览上传文件
allowUpload: true, //是否可以上传
fileManagerJson: '/KindEditor/ProcessRequest', //浏览文件方法
uploadJson: '/KindEditor/UploadImage'//上传文件方法(注意这两个路径)
};
的配置，尤其是fileManagerJson和uploadJson的地址写法，最后就是关于
hash = new Hashtable();
hash["success"] = true;
hash["url"] = fileUrl;
hash["msg"] = "上传成功";
return Json(hash, "text/html;charset=UTF-8");
hashtable 返回时的参数写法
如果是失败的话，当然要返回hash["error"]=1，这些你都要注意。
