Is it possible to target only the direct children of the element specified as the context node with querySelectorAll, without relying on IDs for selection?

Imagine having an HTML structure similar to the one below:

<div id="a">
  <div id="b">
    <div id="c"></div>
  </div>
</div>

When trying to select the children of "a" using querySelectorAll, you could attempt:

//Selecting "b", excluding "c"
document.querySelectorAll('#a > div')

The question at hand: Can this be achieved without specifying the ID and directly referencing the node? I initially tried:

var a_div = document.getElementById('a')
a_div.querySelectorAll('> div') //<-- error here

However, an error occurred indicating that the selector used was invalid.


In a more complex scenario like selecting '> .foo .bar .baz', manual DOM traversal is something I want to avoid. I have resorted to temporarily assigning an ID to the root div, although it feels like a makeshift solution...

Answer №1

document.getElementsByClassName('example').querySelectorAll(':scope > section')

I have found this code to be useful in my projects, especially when I am working with div elements within a specific parent element.

Answer №2

Unfortunately, there is currently no direct way to reference all children of a specific element without first referencing that element itself. The use of the ">" child combinator in CSS requires a parent selector to establish the relationship, which is missing from your example.

In a related note, User123 mentioned that the upcoming Selectors API Level 3 specification is expected to introduce a new method called getAllChildrenexact name subject to change allowing for selectors starting with a combinator rather than a compound selector.
Once this feature is implemented, it may be used in the following manner:

parentElement.getAllChildren('> div');

Answer №3

It seems like there may be some confusion in the question, but here is how I am understanding it:

let a = document.getElementById('a');
let childDivs = a.querySelectorAll('div');

Now, variable childDivs will contain all of your child div elements.
