如何将mycars数组存储在html5的localStorage对象中？

$ b

  var mycars = new Array （）; 
 mycars [0] =萨博; 
 mycars [1] =沃尔沃; 
 mycars [2] =宝马; 
 
 localStorage.mycars = ?; 
  

解决方案

localStorage 用于 key：value 对，所以你可能想要做的是 JSON.stringify the数组并将字符串存储在 mycars 键中，然后您可以将其取出并放回 JSON.parse 它。例如，

  var mycars = new Array（）; 
 mycars [0] =萨博; 
 mycars [1] =沃尔沃; 
 mycars [2] =宝马; 
 
 localStorage [mycars] = JSON.stringify（mycars）; 
 
 var cars = JSON.parse（localStorage [mycars]）; 
  

How to store mycars array in localStorage Object in html5?

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

localStorage.mycars=?;

解决方案

localStorage is for key : value pairs, so what you'd probably want to do is JSON.stringify the array and store the string in the mycars key and then you can pull it back out and JSON.parse it. For example,

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

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

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