cookie操作简单封装

 1 export default {
26   getCookie(name) {
27       let reg = new RegExp(`(^| )${name}=([^;]*)(;|$)`)
28       let arr = document.cookie.match(reg)
29       return arr ? unescape(arr[2]) : null
30   },
31   setCookie(c_name,value,expiredays){
32       var exdate=new Date()
33       console.log(‘teken‘,value);
34       
35       exdate.setDate(exdate.getDate()+expiredays)
36       document.cookie=c_name+ "=" +escape(value)+((expiredays==null) ? "" : ";expires="+exdate.toGMTString())
37   },
38   //删除cookies（配合setcookie进行操作，即设置为空）
39  delCookie(name) {
40       var exp = new Date();
41       exp.setTime(exp.getTime() - 1);
42       var cval=this.getCookie(name);
43       if(cval!=null) document.cookie= name + "="+cval+";expires="+exp.toGMTString();
44   }
45 }
