Ext.onReady(function(){
var formpanel=new Ext.FormPanel({
buttonAlign : 'center',
url:"/VisualSys/servlet/UpLoad",
method:'post',
buttons:[{
text:'上传',
handler:function(){
                formpanel.getForm().submit({
                 clientValidation:true,
                 waitMsg:'上传中,请稍等...',
                 reset:true,
                    success:function(form,action){
                    if(action.result.success){
                     alert('port:'+action.result.data[0].port);
                    }
                },
                failure:function(){
                 Ext.Msg.alert("上传失败！");
                }
                });
}
}],
items:[{
                        xtype: 'textfield',
                        anchor: '90%',
                        inputType: 'file',
                        name:'upfile1',
                        id:'file1'
                    },{
                        xtype: 'textfield',

                        inputType: 'file',
                        name:'upfile2',
                        id:'file2'
                    }]
});
var win,bn;
bn=Ext.get('uploadb');
bn.on('click',function(){
  if(!win){
                    win=new Ext.Window({
                    title:'文件上传',
                    layout: 'fit',
                    width:450,
                    height:350,
                    border: false,
                    closable: true,
                    closeAction: 'hide',
                    bodyStyle: 'padding: 5px;',
                    items:[formpanel]
                    });
  }
      win.show();
                    });
});

Answer 4

你返回的格式有问题，就是前台在解析的时候你的数据不符合JSON格式
