您需要使用getElementsByClassName，它返回一个集合，因此要获取特定元素，您需要使用索引，例如loading [0]，对于addEventListener，第一个参数是事件，在您的情况下为“加载”。

我扔了一些控制台日志来解释正在发生的事情。

var loading = document.getElementsByClassName('loading');

window.addEventListener ("load", function() {
    console.log("page fully loaded");
    //Hide the spinner after 2 seconds
    setTimeout(function(){
        loading[0].style.display = 'none';
        console.log("timeout executed");
    }, 2000);
});
