如何动态设置Javascript对象值？ [英] How to set a Javascript object values dynamically?

问题描述

很难用文字来解释这个案例，让我举一个例子：

It's difficult to explain the case by words, let me give an example:

var myObj = {
    'name': 'Umut',
    'age' : 34
};

var prop = 'name';
var value = 'Onur';

myObj[name] = value; // This does not work

eval('myObj.' + name) = value;   //Bad coding ;)

如何在JavaScript对象中设置具有变量值的变量属性？

How can I set a variable property with variable value in a JavaScript object?

推荐答案

myObj[prop] = value;

这应该有效。您混淆了变量的名称及其值。但是使用字符串索引对象来获取其属性在JavaScript中可以正常工作。

That should work. You mixed up the name of the variable and its value. But indexing an object with strings to get at its properties works fine in JavaScript.
