　　2. login.js：绑定登录界面的功能按钮

var viewModel = function () {
    var self = this;
    this.form = {
        userCode: ko.observable(),
        password: ko.observable(),
        remember: ko.observable(false),
        city: null
    };
    this.message = ko.observable();
    this.loginClick = function (form) {
        if(utils.isEmpty(self.form.password()))// 浏览器记住密码 不执行knockout监听
            self.form.password($("#password").val());
        if(utils.isEmpty(self.form.userCode()))
            self.form.userCode($("#userCode").val());
        $.ajax({
            type: "POST",
            url: rootPath+"/sys/login.do",
