Question

var mara =  [{"name":"zach", "age":"27"}];    
var marathon2 = [{"ticketDetails" : [mara]}];
localStorage.setItem("ticket_marathon2",JSON.stringify($scope.ticket_marathon2));    
var details2 = JSON.parse( localStorage.getItem("ticket_marathon2") );    
console.log("data2",details2);

Answer 1

试试这个：

var mara = [{"name":"zach", "age":"27"}];
var marathon2 = [{"ticketDetails" : mara}];

localStorage.setItem("ticket_marathon2",JSON.stringify(marathon2));

var details2 = JSON.parse( localStorage.getItem("ticket_marathon2") );

alert(JSON.stringify(details2[0].ticketDetails[0].name));

Answer 2

localStorage.setItem("ticket_marathon1", angular.toJson($scope.ticket_marathon1));

var details1 = angular.fromJson(localStorage.getItem("ticket_marathon1"));

注意：您不需要将$ localStorage注入其默认的html5存储空间。

Answer 3

您可以使用

 $window.localStorage.setItem("ticket_marathon1",angular.toJson($scope.ticket_marathon1))

存储， var details1 =angular.fromJson($window.localStorage.getItem("ticket_marathon1"))要检索并$window.localStorage.removeItem("ticket_marathon1")删除。然后您可以访问任何页面中的值，并且更灵活。

注意：在控制器中注入$ window

Answer 4

您有var mara = [{"name":"zach", "age":"27"}]; - 定义为包含一个对象的数组。

之后：var marathon2 = [{"ticketDetails" : [mara]}];

声明“ticketDetails”是一个内部有数组的数组，结果是：

[{“ticketDetails”：[[{“name”：“zach”....}]]}]？

除非是故意的，否则可以删除[]。

另外，在将mara数组添加为对象的值并将其全部字符串化之前，请尝试对mara数组进行字符串化。

如何在localstorage中一次保存数组和对象？
