Ember.js - 多个beforeModel钩子 [英] Ember.js - Multiple beforeModel Hooks

问题描述

在 ember 路线中有多个 beforeModel 钩子有什么问题？

Is there anything wrong with having multiple beforeModel hooks in an ember route?

例如，如果我有一个 mixin ，添加一个 beforeModel 钩子，然后

For example, if I have a mixin that adds a beforeModel hook, and then another beforeModel in the route I'm "mixing in to".

推荐答案

App.Foo = Ember.Mixin.create({
  beforeModel: function(transition, queryParams){
    console.log('foo');
  }
})

App.IndexRoute = Ember.Route.extend(App.Foo,{
  beforeModel: function(transition, queryParams){
    console.log('bar');
  },
  model: function() {
    return ['red', 'yellow', 'blue'];
  }
});

如果你想，可以这样称呼。 _super（param1，param2 ...）从扩展类调用基本方法。

If you want though, you can call this._super(param1, param2...) from the extended class to call the base method.

App.IndexRoute = Ember.Route.extend(App.Foo,{
  beforeModel: function(transition, queryParams){
    this._super(transition, queryParams);
    console.log('bar');
  },
  model: function() {
    return ['red', 'yellow', 'blue'];
  }
});
