Question

我有以下组件：

patientDiseasesStorage = new Object()
patientDiseasesStorage['p158246547'] = [1, 3, 8, 2, 5] //and many more of this with different p-number

我现在尝试保存此对象/数组组合

localStorage.setItem('patientDiseasesStorage', JSON.stringify(patientDiseasesStorage));

但是当我尝试从localStorage读回来时，它没有正确的值：

patientDiseasesStorage = JSON.parse(localStorage.getItem('patientDiseasesStorage'));
patientDiseasesStorage['p158246547'] is now undefined and not the array.

我做错了什么？

Answer 1

如果p158246547是字符串而不是变量名，则它应该有引号：

patientDiseasesStorage['p158246547'] = [1, 3, 8, 2, 5] //and many more of this with different p-number

当你将它从localStorage拉回来时使用引号。

Answer 2

您使用的浏览器是什么？最新的Chrome适合我。

var a = [1, 2,3]
var obj = {'a': a}
obj.a
> [1, 2, 3]
localStorage.setItem('obj', JSON.stringify(obj))
var obj2 = JSON.parse(localStorage.getItem('obj'))
obj2.a
> [1, 2, 3]

localStorage和带有数组的Javascript对象，保存问题
