如下是簡單cookie操作，當前僅限前端實例，具體內容如下
要注意的有兩點：
1、cookie內容存貯的名稱
2、刪除cookie是通過設置過期為過去時間實現的
<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: { //設置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); }, //獲取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>以上就是本文的全部內容，希望對大家的學習有所幫助，也希望大家多多支持錯新站長站。
