如何将mycars数组存储在html5的localStorage对象中？

var mycars = new Array();
mycars[0] = "Saab";
mycars[1] = "Volvo";
mycars[2] = "BMW";

localStorage.mycars=?;

最佳答案

localStorage是针对key : value对的，因此您可能要对数组进行JSON.stringify，并将字符串存储在mycars键中，然后可以将其拉回并对其进行JSON.parse。例如，

var mycars = new Array();
mycars[0] = "Saab";
mycars[1] = "Volvo";
mycars[2] = "BMW";

localStorage["mycars"] = JSON.stringify(mycars);

var cars = JSON.parse(localStorage["mycars"]);
