js中cookie编码解码操作

tokenCook: (name, value, time) => { // 设置cookie
  var exp = new Date()
  exp.setTime(exp.getTime() + time * 60 * 24 * 60 * 1000) // 这里的time就是天数 escape()编码
  document.cookie = name + '=' + escape(value) + ';expires=' + exp.toGMTString()
}

getcookie: (name) => {
  var arr = document.cookie.match(new RegExp("(^| )" + name + "=([^;]*)(;|$)"));
  // 读取cookie          unescape() 解码操作
  if (arr != null) return unescape(arr[2]); return null;
}

 

// 删除cookie
function deleteCookie(name){ 
  var date=new Date(); 
  date.setTime(date.getTime()-10000); 
  document.cookie=name+"=v; expires="+date.toGMTString(); 
}
