传递参数到骨干视图的骨干事件对象 [英] Passing parameters into the Backbone events object of a backbone view

问题描述

我有一个骨干查看下列事件。它的一个产品视图 - 三个选项卡（全部，前3名，五大）

我可以以某种方式传递参数到方法声明，使其等同于以下（不工作）？

 事件：{
        点击＃顶级全：新产品推荐（1）
        点击＃前三名：新产品推荐（2）
        点击＃前十：新产品推荐（3）
    }，
    新产品推荐（OBJ）{
      //做基于OBJ价值的东西
    }
 

解决方案

您可以把额外的参数上，而不是可点击的项目数据属性;是这样的：

 ＆LT;一个ID =顶所有数据煎饼=1＆GT;
 

然后新产品推荐可以自己搞明白：

 新产品推荐：功能（EV）{
    VAR煎饼= $（ev.currentTarget）。数据（'煎饼'）;
    //并继续我们仿佛称为新产品推荐（煎饼）
    // ...
}
 

I have the following events for a Backbone View. Its a product view - with three tabs ("All", "Top 3", "Top 5")

Can I somehow pass a parameter into the method declaration so that it is equivalent to the following (this doesn't work)?

    events : {
        "click #top-all":          "topProducts(1)"
        "click #top-three":      "topProducts(2)"
        "click #top-ten":         "topProducts(3)"
    },
    topProducts(obj){
      // Do stuff based on obj value
    }

解决方案

You could put the extra argument in a data attribute on the clickable item instead; something like this:

<a id="top-all" data-pancakes="1">

And then topProducts can figure it out itself:

topProducts: function(ev) {
    var pancakes = $(ev.currentTarget).data('pancakes');
    // And continue on as though we were called as topProducts(pancakes)
    // ...
}
