Vue browser storage method encapsulation example
Below I will share with you an encapsulation example of vue's browser storage method. It has a good reference value and I hope it will be helpful to everyone.
is as follows:
export function isObject (val) {
return val !== null && typeof val === 'object'
}
export function setStore (key, val, type = 'localStorage') {
if (isObject(val)) window[type].setItem(key, JSON.stringify(val))
else window[type].setItem(key, val)
}
export function getStore (key, type = 'localStorage') {
var val = window[type].getItem(key)
try {
return JSON.parse(val)
} catch (e) {
return val
}
}
export function setSessionStore (key, val) {
setStore(key, val, 'sessionStorage')
}
export function getSessionStore (key) {
return getStore(key)
}
// 默认30minute
export function setExpireStore (key, val, ex = 1.8e6) {
setStore(key, {v: val, t: Date.now() + ex})
}
export function getExpireStore (key) {
var obj = getStore(key)
if (obj.t > Date.now()) return obj.v
else return false
}
export default {
isObject,
setStore,
getStore,
setSessionStore,
getSessionStore,
setExpireStore,
getExpireStore
}The above is what I compiled for everyone. I hope it will be helpful to everyone in the future.
