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（），但它没有用。

Answer 1

内置JSON.parse应该这样做，你不需要任何库：

var obj = JSON.parse(jsonString);

Answer 2

您的字符串不是有效的JSON，因为它包含两个星号。删除它们并在之后应用evalJSON：

str.substring(1, -1).evalJSON(true);

虽然我会说你应该使用JSON.parse（或像json2这样的polyfill）而不是"".evalJSON。

请注意，您将获得一个对象，而不是一个数组！
