kindeditor-4.1.10结合Asp.NetMVC添加图片功能

原作者: [db:作者] 来自: [db:来源] 收藏 邀请

　　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。
