字符串分割为数组

Question

str = [{"id":8,"img":"01.jpg","name":"商品6","discount_price":"1666.00","num":"1","total_money":1666}]（这是由一个类数组转换成了字符串，如何让他转换回去呢？）,请问如何将它分割成[{"id":8,"img":"01.jpg","name":"商品6","discount_price":"1666.00","num":"1","total_money":1666},{"id":8,"img":"01.jpg","name":"商品6","discount_price":"1666.00","num":"1","total_money":1666}]这样的数组呢？

Answer 1

JSON.parse(str)

可以把字符串转成数组或对象……

只是你这个写法

怎么看str都是一个数组……
