就是个存储本地时间看有没有过期写的看着都不好看😂

let old 之前可以写一行 let now = Date.now();
然后代码中的 parseInt(Date.parse(new Date()))都可以替换成 now 了

// 默认一天过期
function storeTime(KeyName, offset = 86400000) {
let now = Date.now();
let old = getStorageSync(KeyName);
if (!old) {
// 第一次进入设置时间缓存 86400000 默认一天
setStorageSync(KeyName, now + offset);
console.log("firstTime 第一次", now + offset);
return "firstTime";
} else {
if (now > old) {
// 超过重新设置过期时间
setStorageSync(KeyName, now + offset);
// true 说明过期
return true;
} else {
return false;
}
}
}
export default storeTime;

```javascript
// 默认一天过期
function storeTime(KeyName, startTime = 86400000) {
const old = getStorageSync(KeyName);
let newTime = parseInt(Date.parse(new Date()));
let statu = false;

if (!old) {
newTime += startTime;
statu = "firstTime";
} else if (newTime > old) {
newTime += startTime;
statu = true;
}

setStorageSync(KeyName, newTime);

return statu;
}
export default storeTime;
```

```js
// 默认一天过期
function storeTime(KeyName, startTime = 86400000) {
const old = getStorageSync(KeyName)
const current = parseInt(Date.parse(new Date()), 10)

if ( old && current < old ) return false
setStorageSync(KeyName, current + startTime)
return !!old ? true : 'firstTime'
}
```

//returnValue: {isFirstTime, isTimeout}
function storeTime(KeyName, timeOutStamp = 86400000) {
let oldTimeStamp = getStorageSync(KeyName);
let nowTimeStamp = parseInt(Date.parse(new Date()), 10);

if (!oldTimeStamp || (nowTimeStamp > oldTimeStamp)) {
let nextTimeoutStamp = nowTimeStamp + timeOutStamp;
setStorageSync(KeyName, nextTimeoutStamp);
return {isFirstTime: !oldTimeStamp, isTimeout: nowTimeStamp > oldTimeStamp};
}

return {isFirstTime: false, isTimeout: false};
}
export default storeTime;
