How to delete cookies in vuejs?

vue.js sets, gets and deletes cookies

The project needs the front-end to obtain the cookies returned by the background and make judgments based on them. I used it under the main.js entry file

Specific code:

new Vue({
el: '#app',
router,
template: &#39;<App/>&#39;,
components: { App },
methods:{
//读取cookie,需要注意的是cookie是不能存中文的,如果需要存中文,解决方法是后端先进行编码encode(),前端取出来之后用decodeURI(&#39;string&#39;)解码。(安卓可以取中文cookie,IOS不行)
    getCookie(name) {
        var arr, reg = new RegExp("(^| )" + name + "=([^;]*)(;|$)");
        if (arr = document.cookie.match(reg)){
        return true;
       // return (arr[2]);
      }else{
      return false
     }
},
//设置cookie   name为cookie的名字,value是值,expiredays为过期时间(天数)
   setCookie (name, value, expiredays) {
     var exdate = new Date();
     exdate.setDate(exdate.getDate() + expiredays);
    document.cookie = c_name + "=" + escape(value) + ((expiredays == null) ? "" : ";expires=" + exdate.toGMTString());
   },
 //删除cookie
   delCookie (name) {
      var exp = new Date();
      exp.setTime(exp.getTime() - 1);
      var cval = getCookie(name);
     if (cval != null)
     document.cookie = name + "=" + cval + ";expires=" + exp.toGMTString();
   }
},
created(){
   this.setCookie(&#39;openId&#39;,123,2)
   if (this.getCookie(&#39;openId&#39;)) {
   console.log(&#39;has cookie&#39;)
  this.delCookie (&#39;openId&#39;)
   }else{
   console.log(&#39;has not cookie&#39;)
   }
}
})
