如何使 createElement('IMG') 可点击？

Question

我的目标是使创建的元素底部 Queen 与顶部 Queen 一样可点击。如何做到这一点？

<!DOCTYPE html>
<html>
<body>
<p><button onclick='createAnImg()'>Create Card</button></p>
<img src='Card Deck/QueenHearts.png' onclick='alert("You picked the Queen of Hearts!")'>
<p id='card_holder'></p>

<script>
function createAnImg() {
x = document.createElement('IMG');
x.setAttribute('id', 'Queen_of_Hearts');
x.setAttribute('src', 'Card Deck/QueenHearts.png');
x.setAttribute('width', '72');
x.setAttribute('alt', 'Card Face');
document.getElementById('card_holder').appendChild(x);
}
</script>

</body>
</html>

只需添加：

x.setAttribute('onclick', 'alert("You picked the Queen of Hearts!")');
