backbone.js视图remove

Backbone.js的remove方法用于从DOM中删除视图。它调用stopListening删除视图具有listenTo的所有绑定事件。

句法:

view.remove()

让我们举个例子。

请参阅以下示例:

<!DOCTYPE html>
   <head>
      <title>View Remove Example</title>
         <script src="https://code.jquery.com/jquery-2.1.3.min.js" type="text/javascript"></script>
         <script src="https://cdnjs.cloudflare.com/ajax/libs/underscore.js/1.8.2/underscore-min.js" type="text/javascript"></script>
         <script src="https://cdnjs.cloudflare.com/ajax/libs/backbone.js/1.1.2/backbone-min.js" type="text/javascript"></script>
   </head>
   <body>
      <div id="mydiv"></div>
      <script type="text/javascript">
         var ViewDemo = Backbone.View.extend({
            events: {'click button': 'removeFunc'
               }, removeFunc: function () {

                  this.remove();

                 document.write("After removing, view becomes: ", $('#mydiv').length);
               }, render: function () {
                  this.$el.html('<button>click to remove</button>');
               }, initialize:function(){this.render();}
         });
         var myview = new ViewDemo({el: '#mydiv'});
      </script>
   </body>
</html>

输出:

将上面的代码保存在remove.html文件中,然后在新的浏览器中打开该文件。
