Is there a way to locate the following image tag following a specific DOM tag, regardless of its sibling status?

In the scenario of HTML code like this:

<html>
<h1>heading</h1>
<div>
  <div>
      <span>
            <img src="source"/>
       </span>
  </div>
</div>
 </html>

The example above is just a template, applicable to any HTML code.

I am looking to target the next image tag after the <h1> element, regardless of its position in the hierarchy.
Using methods such as $('h1').nextAll('img').first() or 

$('h1').nextUntil('img').last().next()
won't be effective here since they are not direct siblings of the <h1>. Is there a more concise way to achieve this without resorting to excessive looping?

javascriptjqueryhtmlcss

Answer №1

const $header = $("h1"); // Selecting the header element
const allElements = $("*"); // Selecting all DOM elements

const headerIndex = allElements.index($header); // Finding index of the header element in all elements
allElements.splice(0, headerIndex); // Removing everything before and including the header element

const firstImage = allElements.filter("img").first(); // Selecting the first image element after the header

Answer №2

Attempt

let imgsNextToH1 = $("* > h1 + * img");

Check out the jsfiddle demo here

Make sure to review the various html structures, nested h1 elements, and multiple img tags included in the test-cases. It also accounts for the original post's html structure.

let images = $("h1 ~ img, h1 ~ * img, *:has(h1) + * + img, *:has(h1) ~ * img")

Another useful jsfiddle link can be found here

Answer №3

$('h1').next().find('img').first()

This should locate the following img element within the immediate sibling.

Modified:

$('h1').nextAll().find('img').first()

This should target the subsequent img element among all adjacent siblings.
