如何在JavaScript中获得所有h1，h2，h3等元素？ [英] How do I get all h1,h2,h3 etc elements in javascript?

问题描述

我想在javascript中写下这样的内容：

I want to write something like this in javascript:

var all_headings = document.getElementsByTagName("h1,h2,h3,h4,h5,h6");

all_headings 会成为全部列表元素是 h1 或 h2 或 h3 ...

all_headings would then be a list of all elements that are h1 or h2 or h3... And in the order that they appear in the document, of course.

我该怎么做？

How do I do it?

推荐答案

使用现代浏览器，您可以执行

With modern browsers you can do

document.querySelectorAll("h1, h2, h3, h4, h5, h6")

或者您可以通过使用jQuery获得跨浏览器兼容性：

Or you could get cross-browser compatibility by using jQuery:

$("h1, h2, h3, h4, h5, h6")
