``我正在尝试将json数据存储在本地存储中。如何将本地存储数据从一个页面获取到同一域中的另一个页面？

在MainPage.html中，“user”存储在localstorage中，我正在打印值 在AddEmploye.html中，数据被附加到存储在本地存储中的用户数据，但是当我转到MainPage.html时，显示的是之前没有插入AddEmploye.html的数据

如何克服这个问题。 谢谢。

MainPage.html

答案 0 :(得分：0)

解决方案

在MainPage.html我注意到您正在运行localStorage.setItem("userData", Data);，这会覆盖从AddEmploye.html添加的所有数据，所以我做的是检查是否{ {1}}中存在{1}}，如果没有，则设置它，否则继续。

您需要注意，使用userData只会覆盖数据，而不会附加到数据上。它就像执行以下操作一样：

localStorage

你希望做更多的事情：

setItem

修改

原来你的解决方案已经有点了，这只是其中一个愚蠢的错误！别担心，即使是我们中最好的人也会时不时地做这样愚蠢的事情。

希望这可以解决您的问题！ :)

＆＃13;
＆＃13; 
var arr = [1];
arr = [2];
＆＃13;
＆＃13;
＆＃13;

编辑2

我有解决方案将用户重定向到下面的MainPage.html。

AddEmployee.html

＆＃13;
＆＃13; 
var arr = [];
arr.push(1);
arr.push(2);
＆＃13;
＆＃13;
＆＃13;

这似乎对我自己很好。我强烈建议你重新编写这个函数，只因为我在30秒内将它拼凑在一起，它很混乱，我很欣赏，但它仍然有效。
