<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()) {
