backbone.js视图属性

Backbone.js属性方法指定属性的哈希,该哈希包含视图el上的HTML DOM元素属性(id,class,data-properties等),或返回此类哈希的函数。

句法:

view.attributes

让我们举个例子。

请参阅以下示例:

<!DOCTYPE html>
   <head>
      <title>View Attributes 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="myapp"></div>
      <script type="text/javascript">
         var MyModel = Backbone.Model.extend({
           defaults: {
               name: "John Davison"
            }
         });

         var ViewDemo = Backbone.View.extend({

            initialize: function () {
               document.write("View is initialized..."+"<br>");

               document.write("My site name is: ", this.model.get("Site")+"<br>");
               document.write("My tag name is: ", this.tagName+"<br>");
               document.write("My class name is: ", this.className);
            }, });
         $(function () {
            var mymodel = new MyModel({ Site: "srcmini" });
            var myview = new ViewDemo({ model: mymodel, tagName: "mytag", className: "myclass"});
            </script>
            </body>
         </html>

输出:

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