Ext.onReady(function(){

var body = Ext.getBody();
Ext.form.TextField.prototype.msgTarget = 'side';
var form1 = new Ext.FormPanel({
id:'formPanel',
labelWidth: 70,
title:'simple form',
bodyStyle:'padding:5px 5px 0',
width: 350,
frame:true,
defaults:{width:230},
url:'http://localhost:8080/extStudy/GetExtFormPanelData',
listeners:{
"actioncomplete":function(_form,_action){
alert("dfas");
}
},
items:[{
xtype:'textfield',
fieldLabel: 'First Name',
name: 'firstName',
allowBlank:false,
blankText:'姓名不能为空',
emptyText:'请输入姓名'
}],
waitMsgTarget: true,
buttons:[{
text:'确定',
handler:function(){
Ext.getCmp("formPanel").getForm().submit({
waitTitle:'wait',
waitMsg:'wait...',
success: function(form, action) {
Ext.Msg.alert('Success', "chen");
} });} }] });
form1.render(body);
});
上边的内容只是想servlet提交一个用户名，但是单submit的时候程序一直处于等待状态，后台什么也没有写只是一个空的servlet（继承了HttpServlet），请问这个是怎么回事 高分一定加到位 请解释清楚 展开

form提交会等待servlet的相应的，servlet应该返回一个json然后在success中解读那个json
