我为我的索引页制作了一个 cookie 弹出窗口，但 html 和 js 看起来正确并且应该可以工作，但不知何故只有橙色按钮可以接受 cookie，当我单击按钮“Noraidīt”时它必须消失但它不执行任何操作，甚至控制台也不会记录消息。有人可以帮忙吗？下面我为您提供代码。

if ( $('.cookie-wrapper').length > 0 ) {


const cookieBox = document.querySelector(".cookie-wrapper"),
acceptBtn = cookieBox.querySelector("button"),
declineBtn = document.querySelector(".decline");

declineBtn.onclick = ()=>{
  console.log("declinebtn");
  document.cookie = "CookieBy=SparkleHeart; max-age="+60*60*24*30;
  if(document.cookie){ //if cookie is set
  
  }else{ //if cookie not set then alert an error
    cookieBox.classList.add("hide"); //hide cookie box
  }
}



acceptBtn.onclick = ()=>{
  //setting cookie for 1 month, after one month it'll be expired automatically
  document.cookie = "CookieBy=SparkleHeart; max-age="+60*60*24*30;
  if(document.cookie){ //if cookie is set
    cookieBox.classList.add("hide"); //hide cookie box
  }else{ //if cookie not set then alert an error
    alert("Cookie can't be set! Please unblock this site from the cookie setting of your browser.");
  }
}
let checkCookie = document.cookie.indexOf("CookieBy=SparkleHeart"); //checking our cookie
//if cookie is set then hide the cookie box else show it
checkCookie != -1 ? cookieBox.classList.add("hide") : cookieBox.classList.remove("hide");

}
