在 JavaScript 中将键数组和值数组合并到一个对象中 [英] Merge keys array and values array into an object in JavaScript

问题描述

我有:

var keys = [ "height", "width" ];
var values = [ "12px", "24px" ];

我想把它转换成这个对象:

And I'd like to convert it into this object:

{ height: "12px", width: "24px" }

在 Python 中，有一个简单的习惯用法 dict(zip(keys,values)).jQuery 或纯 JavaScript 中是否有类似的东西，或者我必须长期这样做?

In Python, there's the simple idiom dict(zip(keys,values)). Is there something similar in jQuery or plain JavaScript, or do I have to do this the long way?

推荐答案

简单的 JS 函数应该是:

Simple JS function would be:

function toObject(names, values) {
    var result = {};
    for (var i = 0; i < names.length; i++)
         result[names[i]] = values[i];
    return result;
}

当然你也可以实际实现像 zip 等函数，因为 JS 支持更高阶的类型，这使得这些函数式语言主义很容易 :D

Of course you could also actually implement functions like zip, etc as JS supports higher order types which make these functional-language-isms easy :D
