<pre class="brush: js;highlight:[12]">var node = document.createElement("div");
var kid1 = document.createElement("p");
var kid2 = document.createTextNode("hey");
var kid3 = document.createElement("span");
node.appendChild(kid1);
node.appendChild(kid2);
node.appendChild(kid3);

var list = node.childNodes;

// 使用 for..of 循环
for(var entry of list.entries()) {
  console.log(entry);
}
</pre>

<p>结果如下:</p>

<pre>Array [ 0, &lt;p&gt; ]
Array [ 1, #text "hey" ]
Array [ 2, &lt;span&gt; ]</pre>
