Backbone.js router.execute()用法及代码示例

当路由与其对应的回调匹配时，Backbone.js execute 方法在路由器内部被调用。

用法:

router.execute(callback, args)

参数说明：

callback:与路由匹配时执行。

args:它指定在 execute 方法中传递的参数。

让我们举个例子。

看这个例子：

<!DOCTYPE html>

      <script type="text/javascript">
         var Route1 = Backbone.View.extend({

            template:'<b>This is route 1</b>',
               initialize:function () {
                  this.execute();
               },
  execute:function () {
                  this.$el.html(this.template);
               }
         });
         var Route2 = Backbone.View.extend({
            template:'<b>This is route 2</b>',
               initialize:function () {
                  this.execute();
               },
               execute:function () {
                  this.$el.html(this.template);
               }
        });

        var AppRouter = Backbone.Router.extend({
           routes:{
              '':'homeRoute',
              'route/1':'homeRoute',
              'route/2':'aboutRoute',
           },

           homeRoute:function () {
              var route1 = new Route1();
              $("#content").html(route1.el);
           },

           aboutRoute:function () {
              var route2 = new Route2();
              $("#content").html(route2.el);
           }
       });
       var appRouter = new AppRouter();   

       Backbone.history.start();
     </script>
  <body>
    <div id="navigation">
       <a href="#/route/1">route1</a>
       <a href="#/route/2">route2</a>
    </div>
    <div id="content"></div>
  </body>
</html>

输出：

将上述代码保存在 execute.html 文件中并在新浏览器中打开此文件。
