vue设置cookie和获取cookie

写法1: 

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(‘;’);
        console.log(“获取cookie,现在循环”)
        for (var i = 0; i < ca.length; i++) {
          var c = ca[i];
          console.log(c)
          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();
    }

 

 

写法2:

    //设置cookie

    /**

    * 设置cookie

    * name cookie的名称

    * value cookie的值

    * day cookie的过期时间

    */

    Vue.prototype.setCookie = function (name, value, day) {

        if (day !== 0) { //当设置的时间等于0时,不设置expires属性,cookie在浏览器关闭后删除

            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);

    }

 

    //在页面中获取cookie  let showcookie = this.getCookie(‘wxshowstated’);

    //在页面中设置cookie  this.setCookie(‘wxshowstated’, ‘1’, 360);
