寫法1:
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(’;’);
console.log(“獲取cookie,現在循環”)
for (var i = 0; i < ca.length; i++) {
var c = ca[i];
console.log©
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);
}
}
}
},
created() {
scroll(0, 0);
this.checkCookie();
}
寫法2:
//設置cookie
/**
* 設置cookie
* name cookie的名稱
* value cookie的值
* day cookie的過期時間
*/
Vue.prototype.setCookie = function (name, value, day) {
if (day !== 0) { //當設置的時間等於0時，不設置expires屬性，cookie在瀏覽器關閉後刪除
var curDate = new Date();
var curTamp = curDate.getTime();
var curWeeHours = new Date(curDate.toLocaleDateString()).getTime() - 1;
var passedTamp = curTamp - curWeeHours;
var leftTamp = 24 * 60 * 60 * 1000 - passedTamp;
var leftTime = new Date();
leftTime.setTime(leftTamp + curTamp);
document.cookie = name + “=” + escape(value) + “;expires=” + leftTime.toGMTString();
} else {
document.cookie = name + “=” + escape(value);
}
}
Vue.prototype.getCookie = function (name) {
var arr;
var reg = new RegExp("(^| )" + name + “=([^;]*)(;|$)”);
if (arr = document.cookie.match(reg))
return unescape(arr[2]);
else
return null; ocument.cookie = name + “=” + escape(value);
}
//在頁面中獲取cookie let showcookie = this.getCookie(‘wxshowstated’);
//在頁面中設置cookie this.setCookie(‘wxshowstated’, ‘1’, 360);
