关于html:取出cookie中的值得逗号等字符转换

设置cookie:
获取cookie：

setCookie(name, value) {    console.log(name, value);    const Days = 3000;    const exp = new Date();    exp.setTime(exp.getTime() + Days * 24 * 60 * 60 * 1000);    document.cookie = name + '=' + escape(value) + ';expires=' + exp.toUTCString();  }  getCookie(name) {    console.log(name);    const strCookie = document.cookie;    const arrCookie = strCookie.split(';');    // tslint:disable-next-line:prefer-for-of    for (let i = 0; i < arrCookie.length; i++) {      const arr = arrCookie[i].split('=');      console.log(arr);      if (arr[0].trim() === name) {        console.log(arr[1]);        return arr[1];      }    }    return '';  }

cookie存储不反对逗号等
获取cookie解决
const arr = str.split('%2C'); // %2C 对应的是 ASCII 字符“,”(英文逗号)
