通过字符串访问JSON成员? [英] Access a JSON member via string?

问题描述

我的JSON:

json_filter = {"CO": "blah"}

我正在尝试通过字符串值访问成员'CO'.但是，结果是不确定的.

I am trying to access the member 'CO' by a string value. However, the result is undefined.

var selectedState = $(this).val();
// Selected 'CO'
console.log(json_filter.selectedState);

我当时以为eval()可能有效，但是eval()==魔鬼:)有更好的方法吗?

I was thinking eval() might work, but eval() == the devil :) Is there a better way to do this?

推荐答案

像这样:

console.log(json_filter[selectedState])
