在没有 jQuery 的情况下在 node.js 上合并或合并 JSON

发布于02月20日

我有JSON个这样的

var object1 = {name: "John"};
var object2 = {location: "San Jose"};

它们不是筑巢之类的.基本上是不同的领域.我需要把它们合并成一个JSON分制的node.js，就像这样:

{name: "John", location: "San Jose"}

我能用jQuery就行了.以下是浏览器中的一个工作示例:

但是如果我在node.js中执行此操作，我不想加载jQuery(这有点过度使用，而且node.js' jQuery在我的Windows机器上不能工作).

So is there a simple way to do things similar to $.extend() without jQuery?

推荐答案

正常循环？

function extend(target) {
    var sources = [].slice.call(arguments, 1);
    sources.forEach(function (source) {
        for (var prop in source) {
            target[prop] = source[prop];
        }
    });
    return target;
}

var object3 = extend({}, object1, object2);

That's a basic starting point. You may want to add things like a hasOwnProperty check, or add some logic to handle the case where multiple source objects have a property with the same identifier.

这是working example美元.

Side note: what you are referring to as "JSON" are actually normal JavaScript objects. JSON is simply a text format that shares some syntax with JavaScript.
