路由器：

define(function (require) { 
    "use strict"; 
    var $ = require('jquery'), 
     Backbone = require('backbone'), 
     _ = require('underscore'), 
     LoginView = require('../views/login'), 
     RecoveryPasswordView = require('../views/recoverypassword'); 
    return Backbone.Router.extend({ 
     routes: { 
      '': 'onViewLogin', 
      'recoverypassword': 'onViewRecoveryPassword' 
     }, 
     onViewLogin: function() { 
      new LoginView(); 
     }, 
     onViewRecoveryPassword: function() { 
      new RecoveryPasswordView(); 
     } 
    }); 
});

首先查看：

define(function (require) { 
    "use stritc"; 
    var $ = require('jquery'), 
     _ = require('underscore'), 
     Handlebars = require('handlebars'), 
     Backbone = require('backbone'), 
     template = Handlebars.compile($('#login-template').html()), 
     HomeView = require('../views/home'), 
     Util = require('util'); 
    return Backbone.View.extend({ 
     el: '#app', 
     events: { 
      'click #button-login': 'onLogin' 
     }, 
     ui: function() { 
      return { 
       email: this.$('input[name="email"]'), 
       password: this.$('input[name="password"]') 
      } 
     }, 
     initialize: function() { 
      this.render(); 
     }, 
     render: function() { 
      this.$el.html(template()); 
      return this; 
     }, 
     onLogin: function (event) { 
      if (_.isEmpty(this.ui().email.val())) { 
       navigator.notification.alert('El Correo electronico es requerido.', null, 'Notificación', 'Aceptar'); 
       return false; 
      } 
      if (_.isEmpty(this.ui().password.val())) { 
       navigator.notification.alert('La contraseña es requerido', null, 'Notificación', 'Aceptar'); 
       return false; 
      } 
      if (!Util.regExpEmail().test(this.ui().email.val())) { 
       navigator.notification.alert('El Correo Incorrecto.', null, 'Notificación', 'Aceptar'); 
       return false; 
      } 
      $.getJSON(Util.baseUrl() + 'auth/' + this.ui().email.val() + '/' + this.ui().password.val(), {}, function (response) { 
       if (response.status == 'success') { 
        localStorage.user = JSON.stringify({ 
         'id': response.data.intIdUser, 
         'name': response.data.strUsername, 
         'email': response.data.strEmail, 
         'specialty': response.data.intIdSpecialty 
        }); 
        new HomeView(); 
       } else { 
        navigator.notification.alert(response.message, null, 'Notificación', 'Aceptar'); 
        return false; 
       } 
      }); 
     } 
    }); 
});

SECONDO查看：

define(function (require) { 
    "use stritc"; 
    var $ = require('jquery'), 
     Handlebars = require('handlebars'), 
     Backbone = require('backbone'), 
     template = Handlebars.compile($('#recoverypassword-template').html()), 
     LoginView = require('../views/login'), 
     Util = require('util'); 
    return Backbone.View.extend({ 
     el: '#app', 
     events: { 
      'click #button-recoverypassword': 'onValidate' 
     }, 
     ui: function() { 
      return { 
       email: this.$("input[type='email']") 
      }; 
     }, 
     initialize: function() { 
      this.render(); 
     }, 
     render: function() { 
      this.$el.html(template()); 
      return this; 
     }, 
     onValidate: function() { 
      if (_.isEmpty(this.ui().email.val())) { 
       navigator.notification.alert('El Correo electronico es requerido.', null, 'Notificación', 'Aceptar'); 
       return false; 
      } 
      if (!Util.regExpEmail().test(this.ui().email.val())) { 
       navigator.notification.alert('El Correo Incorrecto.', null, 'Notificación', 'Aceptar'); 
       return false; 
      } 
      $.getJSON(Util.baseUrl() + 'recoverypassword/' + this.ui().email.val(), {}, function (response) { 
       if (response.status == 'success') { 
        navigator.notification.alert(response.message, null, 'Notificación', 'Aceptar'); 
        new LoginView(); 
       } else { 
        navigator.notification.alert(response.message, null, 'Notificación', 'Aceptar'); 
        return false; 
       } 
      }); 
     } 
    }); 
});
