document.getElementsByClassName返回一个数组，所以你必须遍历它或使用jQuery，例如：

var elements = document.getElementsByClassName('w3-button w3-hover-black'); 
for (var i = 0; i < elements.length; i++) {
   elements[i].addEventListener("click", function(){
      window.location.href = "https://localhost:3000/game.html";
   });
}

问题是getElementSbyClassName返回所有具有此类名的元素的数组，例如在第一个元素上具有OnClick函数：

document.getElementsByClassName('w3-button w3-hover-black')[0].onclick =

字符串
你将不得不覆盖它们，并像这样为每个对象附加一个处理程序：

var elts = getElementsByClassName('w3-button w3-hover-black');
for( var i=0,il = elts.length; i< il; i ++ ){
 elts[i].onclick = 

function(){
//your code..
}
