  • 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;
    }

                        return 1;
                    }
                    FileInfo xInfo = new FileInfo(x.ToString());
                    FileInfo yInfo = new FileInfo(y.ToString());
    
                    return xInfo.Extension.CompareTo(yInfo.Extension);
                }
            }
        }
    }
    

      

    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。
