一个简单的登录表单：
[
',handler:function(b){
var formObj = Ext.getCmp("my_form");//表单id
var basic = formObj.getForm();//得到表单
var nameField = basic.findField("userName");//得到文本域
var nameValue = nameField.getValue();//得到文本域的值
alert(nameValue);
}},{
text:'重置',handler:function(b){
var formObj = Ext.getCmp("my_form");
var basic = formObj.getForm();
basic.reset();
}
},{
text:'装在数据',handler:function(b){
var formObj = Ext.getCmp("my_form");
var basic = formObj.getForm();
basic.loadRecord(p);//p为model类型
}
}
]
})
});
