EXT+SWFUpload文件上传.doc

服务器返回（PHP），其他的语言只要返回值为JSON就行成功：json_encode(array(state=true,info=上传成功,servername=服务器保存的文件名（不带扩展名）,linkurl=保存路径,filemaxid=公告记录ID（可以根据需要不用）,fileext=文件扩展名);失败：json_encode(array(state=false,info=错误信息);如果要做为HTMLEDITOR的一个图标使用，加以下代码，在EXT-all-debug.js文件HTMLEDITOR控件内容中，具体位置找一下啰注意要给HTMLEDITOR加个参数：uploadfileConfig: tb.add(-,itemId:uploadfile,iconCls: uploadfile,scope: editor,handler: function()var tmpuploadwin = Ext.getCmp(this.id+_uploadwin);if(!tmpuploadwin)this.uploadfileConfig.upload_win_id = this.id+_uploadwin;this.uploadfileConfig.upload_type = 1;
