问题描述
我有一个非常简单的 JSON 数组(请关注 "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
但是,不幸的是,它没有显示任何内容.
当我将 "points.bean.pointsBase" 更改为名称中没有点的 smth 时 - 一切正常!
但是,我不能将此名称更改为没有点的任何其他名称,但我需要获取一个值?!
有什么办法可以得到吗?
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,您可以使用 .运算符,您可以使用 [] 和字段名称的字符串版本进行访问.
In JavaScript, any field you can access using the . operator, you can access using [] with a string version of the field name.
