tinymce 添加本地图片功能 出错

Question

小妹不是很懂js 被这破玩意整到半夜 半条命都没了 谁来救救我啊 help help help原tinymce是没有上传本地图片的功能的 偏偏我就需要用这条功能现在我实现了上传功能 url也返回来了 在ie中也能浏览了..就是值返不回正文以下是我修改的代码
 var imgurl;
        function Test() {
            alert('sdfsd');
            $('#myForm').ajaxSubmit({
                beforeSubmit: function () {
                    alert("act!");
                },
                success: function (html, status) {
                    var result = html.replace("<PRE>", "");
                    result = result.replace("</PRE>", "");
                    imgurl=result;
                    $("#upImg").val(result);
                    ImageDialog.showPreviewImage(result);//到这都没有问题                    //此处是我从另一篇blog里截到的代码 本以为能通过这个把值返回去的...
                    var FileBrowserDialogue = {
                          init:function () {
                              var win = tinyMCEPopup.getWindowArg("window");
                             (tinyMCEPopup.getWindowArg("input")).value = imgurl;
                             tinyMCEPopup.close;
                          }
                   };
                     tinyMCEPopup.onInit.add(FileBrowserDialogue.init, FileBrowserDialogue);
                } 
            });
         }
