我是靠谱客的博主忧虑爆米花，最近开发中收集的这篇文章主要介绍VUE前端cookie简单操作，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

如下是简单cookie操作，当前仅限前端实例，具体内容如下

要注意的有两点：

1、cookie内容存贮的名称
2、删除cookie是通过设置过期为过去时间实现的

<body>
<div id="app">
 <button @click="clearCookie()">
 清除cookie
 </button>
</div>
</body>
<script>
 let app = new Vue({
 el: "#app",
 data: {
 },
 created: function () {
  this.checkCookie();
 },
 methods: {
  //设置cookie
  setCookie: function (cname, cvalue, exdays) {
  var d = new Date();
  d.setTime(d.getTime() + (exdays * 24 * 60 * 60 * 1000));
  var expires = "expires=" + d.toUTCString();
  console.info(cname + "=" + cvalue + "; " + expires);
  document.cookie = cname + "=" + cvalue + "; " + expires;
  console.info(document.cookie);
  },
  //获取cookie
  getCookie: function (cname) {
  var name = cname + "=";
  var ca = document.cookie.split(';');
  for (var i = 0; i < ca.length; i++) {
   var c = ca[i];
   while (c.charAt(0) == ' ') c = c.substring(1);
   if (c.indexOf(name) != -1) return c.substring(name.length, c.length);
  }
  return "";
  },
  //清除cookie
  clearCookie: function () {
  this.setCookie("username", "", -1);

  },
  checkCookie: function () {
  var user = this.getCookie("username");
  if (user != "") {
   alert("Welcome again " + user);
  } else {
   user = prompt("Please enter your name:", "");
   if (user != "" && user != null) {
   this.setCookie("username", user, 365);
   }
  }
  }
 }
 })
</script>
