利用Ext.ux.UploadDialog实现文件上传
var dialog = new Ext.ux.UploadDialog.Dialog({ title:'本地图片上传', url: '<%=basePath%>shop/link/link_edit!uploadImage.action', post_var_name:'imageUpload', //参数名 reset_on_hide: false, modal: true, permitted_extensions:['JPG','jpg','JPEG','jpeg','GIF','gif','PNG','png'], //上传类型限制 allow_close_on_upload: true, //窗口关闭后继续上传 upload_autostart: true //是否自动上传 }); dialog.show();//上传成功后回调函数dialog.on('uploadsuccess',function(dialog, filename, resp_data, record){//上传成功后，返回的路径,设置在表单imageUrl文本框中 Ext.getCmp('imageUrl').setValue(resp_data.data.msg);//关闭窗口并显示提示信息 dialog.hide(); Ext.Msg.alert("系统提示", "文件上传成功！");});?
