问题描述

在我的ribs.js视图中，我有一个包含以下代码的函数.我通常会使用this.addLayerToList()调用此函数，但是由于它在$.each中.不是我想要的有人可以帮忙吗?如何从$.each调用函数addLayerToList?

In my backbone.js view i have a function that has the code below. I would usually call this function using this.addLayerToList(), but since it's in the $.each this. is not what I want. Can anyone help here? How would I call my function addLayerToList from the $.each?

initLayerList: function(){
   $.each(baseLayers, function() {
       this.addLayerToList(this);
   });
},

addLayerToList : function() {
     //...some code here
}

推荐答案

这应该有效.

initLayerList: function(){
   var that = this;
   $.each(baseLayers, function(idx, layer) {
       that.addLayerToList(layer);
   });
},

addLayerToList : function() {
     //...some code here
}
