　　2. login.js：綁定登錄界面的功能按鈕

var viewModel = function () {

    this.form = {

    };
    this.message = ko.observable();
    this.loginClick = function (form) {
        if(utils.isEmpty(self.form.password()))// 瀏覽器記住密碼 不執行knockout監聽
            self.form.password($("#password").val());
        if(utils.isEmpty(self.form.userCode()))
            self.form.userCode($("#userCode").val());
