Is there a way to identify all rows that have been styled using CSS in JS?

I am looking to identify the rows that have been selected through CSS using Javascript. I have attempted some approaches with code snippets gathered from various sources. Here is an example below:

...
var tableRows = document.getElementsByTagName('tr');

for (var j = 2; j < tableRows.length; j++)
...

As seen in other discussions, here is another snippet that counts the number of checked input elements with specific IDs:

...
var totalSelectedInputs = document.querySelectorAll("input[id$='inpt']:checked").length;
...

In regards to CSS styling: table tbody .selected tr { background-color: #E74C3C; }

How can the provided code snippets be utilized as references to effectively track and identify all selected rows through CSS in Javascript?

Answer №1

It appears that you are attempting to target the identical elements with JavaScript as those selected by your CSS styles.

If this is the case, simply utilize the same selector in your JavaScript code.

var selectedElements = document.querySelectorAll(`table tbody .selected tr`);

Executing this will result in an array containing all the elements that have been styled with background-color: #E74C3C;
