无法在同一个类中访问变量 [英] Can't access variable inside same class

问题描述

var BooksView = Backbone.View.extend({

    initialize: function() {
        this.render();
    },

    render: function() {
       alert(this.myVar);
    }
});

和我的路由器:

var BookRouter = Backbone.Router.extend({
   routes: {
      '': 'index',
      'list/:id': 'list'
   },

   index: function(){
      var booksView = new BooksView({
         el: ".content",
         myVar: "Example 1"
      });
   },
   list: function(id){
      var booksView = new BooksView({
         el: ".content",
         myVar: "Example 2"
      });
   }
});

如何访问变量?即使变量设置在同一类中，this.myVar似乎也不起作用?

How do I access the variable? this.myVar doesn't seem to be working, even though the variable is set inside the same class?

推荐答案

从主链版本1.1.0 ribs.js不再自动为您附加所有选项，但是您仍然可以在初始化功能.

As of backbone version 1.1.0 backbone.js no longer attaches all options for you automatically, however you can still do this yourself manually inside your initialize function.

例如

 initialize: function(options) {
      if (options) {
        _.extend(this, options);
      }
      this.render();
    },
