如何在本地存储中存储变量？ [英] How to store a variable in local storage?

问题描述

我正在运行一个脚本，我正在使用元刷新，因为它可能因互联网连接或服务器停机或其他任何事情而停止：

I am running a script and I am using a meta refresh as it could stop due to internet connection or server downtimes or anything:

<meta http-equiv="refresh" content="30">

脚本需要一个起始变量，每次脚本运行时都会更新，所以我想保存该变量在本地存储中的最新值，但通过这种方式，该值将始终被覆盖到起始值

The script requires a starting variable, this will update every time the scripts runs, so I want to save the latest value for that variable in local storage but by putting it this way, the value will always be overwritten to the starting value

var myId = 47911111;
localStorage.setItem('titles', myId);

推荐答案

首先检查您的浏览器是否支持这样的本地存储（ 本地存储将在页面刷新期间保持不同于sessionStorage ）

First check if your browser supports local storage like this (local storage will persist across page refreshes unlike sessionStorage)

if (typeof(Storage) !== "undefined") {
    // Code for localStorage/sessionStorage.
    // Store value
    localStorage.setItem("keyName", variable);
   // Retrieve value from local storage and assign to variable
   var myId = localStorage.getItem("keyName");
} else {
    // Sorry! No Web Storage support..
}
