Question

我正在尝试理解JS引用。

<a id="ohnoes" href="https://www.kasandbox.org/programming-sounds/rpg/giant-no.mp3">What does Oh Noes say?</a>`

所以我在这个函数中引用了上面的标记：

var ohnoesEl = document.getElementById("ohnoes");
var onOhNoesClick = function(e) {
    e.preventDefault();
    var audioEl = document.createElement("audio");
    audioEl.src = "https://www.kasandbox.org/programming-sounds/rpg/giant-no.mp3";
    audioEl.autoplay = "true";
    document.body.appendChild(audioEl);
    };

为什么这样做：

audioEl.src = "https://www.kasandbox.org/programming-sounds/rpg/giant-no.mp3";

但不是这样：

audioEl.src = ohnoesEl.href;
