在我们为了去完成数据储存，有时会用到cookie，简单封装一下cookie：
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Document</title>
</head>
<body>
<script type="text/javascript">
//设置cookie
function setCookie(name,value,days){
days=days?days:30;//一个月后失效
var exp=new Date();
exp.setTime(exp*1+days*24*60*60*1000);
document.cookie=name+"="+escape(value)+";expires="+exp;
}
setCookie("tel","13546",10);
setCookie("name","arch",1);
console.log(document.cookie);
//获取cookie
function getCookie(name){
var reg=new RegExp(‘(^| )‘+name+‘=([^;]*)(;|$)‘);
var arr=document.cookie.match(reg);
if(arr) return arr[2];
return null;
}
getCookie("name");
console.log(getCookie("name"));
//删除cookie
function delCookie(name){
if(getCookie(name)){
setCookie(name,"",-1);
}
}
delCookie("tel");
</script>
</body>
</html>
