用js向cookie中保存数据、获取数据的方法如下：\x0d\x0afunction GetCookieVal(offset)\x0d\x0a//获得Cookie解码后的值\x0d\x0a{\x0d\x0avar endstr = document.cookie.indexOf ("", offset)\x0d\x0aif (endstr == -1)\x0d\x0aendstr = document.cookie.length\x0d\x0areturn unescape(document.cookie.substring(offset, endstr))\x0d\x0a}\x0d\x0a\x0d\x0a//---------------------------\x0d\x0afunction SetCookie(name, value)\x0d\x0a//设定Cookie值\x0d\x0a{\x0d\x0avar expdate = new Date()\x0d\x0avar argv = SetCookie.arguments\x0d\x0avar argc = SetCookie.arguments.length\x0d\x0avar expires = (argc >2) ? argv[2] : null\x0d\x0avar path = (argc >3) ? argv[3] : null\x0d\x0avar domain = (argc >4) ? argv[4] : null\x0d\x0avar secure = (argc >5) ? argv[5] : false\x0d\x0aif(expires!=null) expdate.setTime(expdate.getTime() + ( expires * 1000 ))\x0d\x0adocument.cookie = name + "=" + escape (value) +((expires == null) ?

回答于 2022-12-111. 最近得到一个新需求，需要在后台管理页面加上用户权限控制，通过后台放在cookie里面的token进行判断；
2. 获取cookie里面的token：
2.1 我们在用vue.js里面的index.html写一个全局的函数:
3. 这样我们通过传入cookie的key名就可以获取到后面的token了，如：
get(cookie){
let cookieValue=null
let cookies=document.cookie.split('')
for(var i=0i<cookies.lengthi++){
let cookie=cookies[i].trim()去掉前后的空格
if(cookie.substring(0,name.length+1)==(name+'=')){
cookieValue=decodeURICompoent(cookie.substring(name.length+1)）
break
}
}
return cookieValue
}、
