如何获得JSON对象的价值如果名称中包含点？ [英] How to get JSON objects value if its name contains dots?

问题描述

我有一个非常简单的JSON数组（请重点关注的points.bean.pointsBase对象）：

I have a very simple JSON array (please focus on "points.bean.pointsBase" object):

var mydata =   
{"list":  
  [  
    {"points.bean.pointsBase":  
      [  
        {"time": 2000, "caption":"caption text", duration: 5000},  
        {"time": 6000, "caption":"caption text", duration: 3000}  
      ]  
    }  
  ]  
};  

// Usually we make smth like this to get the value: 
var smth = mydata.list[0].points.bean.pointsBase[0].time; 
alert(smth); // should display 2000

但不幸的是，它什么都不显示。

当我更改points.bean.pointsBase以SMTH没有它的名字点 - 一切正常


但是，我不能这个名称更改为别的不点，但我需要得到一个值？

是否有任何选项得到它？

But, unfortunately, it does display nothing.
When I change "points.bean.pointsBase" to smth without dots in it's name - everything works!

However, I can't change this name to anything else without dots, but I need to get a value?!
Is there any options to get it?

推荐答案

你想要的是：

var smth = mydata.list[0]["points.bean.pointsBase"][0].time;

在JavaScript中，任何领域，您可以访问使用。运营商，您可以访问使用[]的字段名的字符串版本。

In JavaScript, any field you can access using the . operator, you can access using [] with a string version of the field name.
