在初始化步骤中，将this作为一个选项传递给子视图：

var ChildView = Backbone.View.extend({
  initialize : function (options) {
    this.parent = options.parent;
  }
});

// somewhere in the parent view ...
new ChildView({parent:this});

// You can use this code instead

var ChildView = Backbone.View.extend({
  initialize : function (options) {
    this._configure(options); // Set all the options as local variables
    // This is used in the Backbone.View code on the latest version

  }
});
