获取到网页script里面的JSON文本，请问如何不使用eval转换为JSON？

http://www.JSON.org/json2.js 算是一种解决方案吧

@haozxuan 请问下如何使用啊？

@youqingkui 百度下，json.pase 就有大神标注坑，当然也有解决方案。

不要用eval，先找到json.parse 解析失败的原因啊。

亲，把文本和报错的信息贴出来

用JSON.parse的话一定要保证是严格的json格式，属性和属性值的双引号不能缺，eval则不需要严格的json格式

“songs = [obj1, obj2, …]” 是普通的js赋值语句，不是json。
