json.js和json2.js之间的区别 [英] Difference between json.js and json2.js

问题描述

有人可以告诉我2个JSON解析器之间的区别是什么吗?

Can someone tell me what the difference is between the 2 JSON parsers?

我有一个2007年4月13日起的JSON文件(它具有诸如parseJSON之类的方法).我没有在任何新版本中看到这些方法.

I have a JSON file from 2007-04-13 (It has methods such as parseJSON). I don't see these methods in any of the new versions.

推荐答案

从他们的代码中获取:

// Augment the basic prototypes if they have not already been augmented.
// These forms are obsolete. It is recommended that JSON.stringify and
// JSON.parse be used instead.

if (!Object.prototype.toJSONString) {
    Object.prototype.toJSONString = function (filter) {
        return JSON.stringify(this, filter);
    };
    Object.prototype.parseJSON = function (filter) {
        return JSON.parse(this, filter);
    };
}

我猜parseJSON已过时，因此新版本(json2)甚至不再使用它.但是，如果您的代码大量使用parseJSON，则可以将这段代码添加到某个地方以使其再次起作用:

I guess parseJSON is obsolete, therefore the new version (json2) doesn't even use it anymore. However if your code uses parseJSON a lot you could just add this piece of code somewhere to make it work again:

    Object.prototype.parseJSON = function (filter) {
        return JSON.parse(this, filter);
    };

这篇关于json.js和json2.js之间的区别的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
