如何在localStorage中存储数组？

Question

I have to store an array in window.localStorage . How would I store the array in window.localStorage using console window?

EX:
cards: Array[0]
length: 0

I have to store this. Now here key is cards and length is nested.

localStorage only support string so you'll have to parse it to JSON

 var arr = ["hello", "how", "are", "you", "doing"]; localStorage.setItem("test", JSON.stringify(arr));
