localStorageis for key : valuepairs, so what you'd probably want to do is JSON.stringifythe array and store the string in the mycarskey and then you can pull it back out and JSON.parseit. For example,
localStorage是key : value成对的，所以你可能想要做的是JSON.stringify数组并将字符串存储在mycars键中，然后你可以把它拉回来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"]);

LocalStoragecan store strings and not arrays directly. Use some special symbol like '~'to concatenate the elements of array and save it as an array. When retrieving , using split('~')to get back the array.
LocalStorage可以直接存储字符串而不是数组。使用像'~'这样的特殊符号来连接数组的元素并将其保存为数组。检索时，使用split('~')取回数组。
