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

问题描述

文字很难解释，我举个例子:

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;

应该可以.您混淆了变量的名称及其值.但是用字符串索引对象以获取其属性在 JavaScript 中工作正常.

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.
