ExtJs4+struts2文件上传后弹出下载框
ExtJs4.2+struts2文件上传成功后，弹出下载框没有回调函数。
js代码：
createUploadWindow: function(config) {

form1.add(this.createResourceFileAddButtonFieldset(config));
form1.doLayout();
//
btns.push({
text: '上传',
listeners : {
'click': function(){
var fm = form1.getForm();
if(fm.isValid()) {
if(Ext.getCmp('upload').getValue() == ''){
Ext.Msg.alert('提示','请上传图片');
return;

var fileName = Ext.getCmp('upload').getValue();
fileName = fileName.substring(fileName.lastIndexOf('\\')+1,fileName.length);
