Question

我使用浏览器localStorage来存储值，但在使用Google Chrome时，当我们使用window.location.reload()刷新页面时，localStorage.value会被刷新。例如

localStorage.value1=true

重新加载后，我没有在localStorage中获取此value1对象。

相同的代码适用于mozila firefox，但不适用于chrome。使用firefox时，localstorage值是持久的。

Answer 1

LocalStorage仅支持字符串值，而不支持布尔值或其他值。

存储和检索值的方法：

将值存入存储

localStorage.setItem('value1', 'true');

从存储中检索值

var val1 = localStorage.getItem('value1');

Answer 2

您需要使用正确的API for Storage：

window.localStorage.setItem('value1', 'true');

您正在做的是在变量上设置属性，该变量在页面加载之间不会持续存在。 Firefox可能过于聪明，并且认识到您希望将该值实际保存在浏览器的本地存储中。

Answer 4

试试吧

window.localStorage.setItem("value1", true);

var yourvar = window.localStorage.getItem("value1");

localStorage不支持谷歌浏览器
