NodeList.entries() - Web API 接口参考 编辑

该方法返回一个迭代协议，允许遍历此对象中包含的所有键/值。该值也是一个Node 对象。

语法

list.entries();

返回值

例子

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);
}

结果如下:

Array [ 0, <p> ]
Array [ 1, #text "hey" ]
Array [ 2, <span> ]
