javascript - 使用 Prototype 将字符串转换为 JSON 数组？

Question

我有这个 json 字符串:

{"17":{"31":{"price":5,"oldPrice":5,"priceValue":"5.0000","type":"fixed","excludeTax":5,"includeTax":5},"29":{"price":8,"oldPrice":8,"priceValue":"8.0000","type":"fixed","excludeTax":8,"includeTax":8},"30":{"price":10,"oldPrice":10,"priceValue":"10.0000","type":"fixed","excludeTax":10,"includeTax":10}},"12":{"price":0,"oldPrice":0,"priceValue":"0.0000","type":"fixed","excludeTax":0,"includeTax":0},"11":{"price":0,"oldPrice":0,"priceValue":"0.0000","type":"fixed","excludeTax":0,"includeTax":0}}

如何使用 Prototype 将其转换为数组？我尝试了 evalJSON()，但没有成功。

内置JSON.parse应该这样做，你不需要任何库:

var obj = JSON.parse(jsonString);
