如果数据里不包含正则、函数等非JSON类型，JSON.stringify是可以的，请问报什么错？

方便发下两种使用方式？是用$cache接口吗？

就是存如图的自定义对象，存不了，类似hashmap，单独存储 var a = [];是可以的。应该不是 $cache接口的问题，是JSON.stringify 转不了

没有看出问题，tempGoodsArray 应该不是一个数组吧，如果没有挂一些非基本类型的实例字段，也不会有问题，或许你可以尝试下 JSON.stringify(tempGoodsArray) 会报什么错

JSON.stringify(tempGoodsArray)不会报错，但这个对象在h5上是可以存储的
