JavaScript 节点列表 [英] JavaScript NodeList

问题描述

有没有办法加入由 2 次调用 document.getElementsByTagName 返回的 2 个 NodeList?

is there a way to join 2 NodeLists returned by 2 calls of document.getElementsByTagName?

说，我有以下代码

var inputs = documentElement.getElementsByTagName('input');
var selects = document.getElementsByTagName('select');

我想遍历结果.可以在一个循环中吗?

I want to loop through the results. Is it possible in one loop?

先谢谢你！

推荐答案

似乎可以使用相同的 Array.prototype.slice.call 使 args 类数组对象成为数组.(见这里)

Seems like you can use the same Array.prototype.slice.call that makes the args array-like object become an array. (See here)

var inputs = document.getElementsByTagName('input');
var selects = document.getElementsByTagName('select');

inputs = Array.prototype.slice.call(inputs);
selects = Array.prototype.slice.call(selects);

var res = inputs.concat(selects);

alert(res.length);
