主干.js:从子视图访问父视图

Question

一般来说，如何从 Backbone 中的子视图访问父视图？

具体来说，在 Backgrid.js 中，有没有办法从单元格访问父行？

Answer 1

在初始化步骤中将this作为选项传递给子视图：

var ChildView = Backbone.View.extend({
  initialize : function (options) {
    this.parent = options.parent;
  }
});
// somewhere in the parent view ...
new ChildView({parent:this});

Answer 2

// 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
  }
});
