ExtJs表单提交登陆实现代码

//登陆按钮单击事件
loginFun: function() {
var f = Ext.getCmp("loginForm");
//表单验证
if (f.form.isValid) {
f.form.submit({
waitTitle: "请稍候",
waitMsg: '正在登陆...',
url: 'http://www.cnblogs.com/Service/SystemService/SystemService.ashx?Method=UserLogin',
method: 'POST',
success: function(form, action) {
window.location = 'Main.htm'
},
failure: function(form, action) {
if (action.result == undefined) {
Ext.Msg.alert('提示', "系统出错...请联系管理员");
form.items.items[1].reset();
}
else {
Ext.Msg.alert('提示', action.result.rspText);
form.items.items[1].reset();
}
}
});
}
},

//初始化
init: function() {
this.LoginWin.show();
Ext.getCmp("loginBtn").on('click', this.loginFun);
this.loadMask = new Ext.LoadMask(this.LoginWin.body, { msg: "页面加载中……" });
}

public void UserLogin()
{
StringBuilder jsOnData= new StringBuilder();
bool success = false;
string rspText = string.Empty;
if (Request["LoginName"] != null && Request["LoginPsd"] != null)
