cookie操作
有时候前端需要操作登录态,基本是用cookie来操作,那一般cookie怎么用js操作呢
/** * cookie操作 */ export const getCookie = name => { var arr = document.cookie.split(';') for (var i = 0; i < arr.length; i++) { var item = arr[i].replace(/\s+/g, '') if (item.indexOf(name) != -1) { item = unescape(item) return item.split('=')[1] } } return false } export const clearCookie = name => { this._setCookie(name, '', -1) } export const setCookie = (name, value, seconds) => { seconds = seconds || 0 var expires = '' if (seconds != 0) { var date = new Date() date.setTime(date.getTime() + seconds * 1000) expires = '; expires=' + date.toGMTString() } document.cookie = name + '=' + value + expires + '; path=/' }
上面封装了三个方法,一个是获取cookie,一个是清除cookie,一个是设置cookie。尤其是设置的时候,第三个参数是设置过期时间。
