javascript - 如何在 Backbone.js 中处理简单的点击事件？

Question

我在 Backbone 中遇到一些非常简单的问题。我想连接<h1>在我的页面中，以便当用户单击它时，它会无缝返回到主页，而无需回发。

这是 HTML:

<h1><a id="home" href="/">Home</a></h1>

(更新:按照评论者的建议修复了 ID。)这是我的 Backbone View 和路由器:

var HomeView = Backbone.View.extend({
  initialize: function() { 
    console.log('initializing HomeView');
  },
  events: { 
    "click a#home": "goHome"
  }, 
  goHome: function(e) { 
    console.log('goHome');
    e.preventDefault();
    SearchApp.navigate("/");
  }
});
var SearchApp = new (Backbone.Router.extend({
  routes: { 
    "": "index", 
  },
  initialize: function(){
    console.log('initialize app');
    this.HomeView = new HomeView();
  },
  index: function(){
    // do stuff here
  },
  start: function(){
    Backbone.history.start({pushState: true});
  }
}));
$(document).ready(function() { 
  SearchApp.start();
});

控制台正在向我显示

initialize  app
initializing HomeView 

但是当我点击<h1>时，页面回发 - 但我没有看到 goHome在控制台中。

我做错了什么？显然我可以连接 <h1> click 事件在 jQuery 中足够简单，但我想了解应该如何在 Backbone 中执行此操作。

如果启用pushState，则需要拦截所有点击并防止刷新:

$('a').click(function (e) {
  e.preventDefault();
  app.router.navigate(e.target.pathname, true);
});

类似于:

$(document).ready(function(){

  var HomeView = Backbone.View.extend({
    initialize: function() { 
      console.log('initializing HomeView');
    }
  });

  var AboutView = Backbone.View.extend({
    initialize: function() { 
      console.log('initializing AboutView');
    }
  });

  var AppRouter = Backbone.Router.extend({
    routes: { 
      "": "index", 
      "about":"aboutView"
    },

    events: function () {
      $('a').click(function (e) {
        e.preventDefault();
        SearchApp.navigate(e.target.pathname, true);
      });
    },

    initialize: function(){
      console.log('initialize app');
      this.events();
      this.HomeView = new HomeView();
    },

    index: function(){
      this.HomeView = new HomeView();
    },

    aboutView : function() {
      this.AboutView = new AboutView();
    }
  });

  var SearchApp = new AppRouter();
  Backbone.history.start({pushState: true});

});
