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>
