代码看起来不错，但仍然收到添加事件处理程序的错误
document.addEventListener('DOMContentLoaded', function() {
let count = 0
let countEl = document.getElementById("count-el")
function increment() {
count = count + 1
countEl.innerText=count;
// set countEl's innerText to the count
}
increment()
countEl.addEventListener("click", increment);
});
