Toggle multiple checkbox elements enabled/disabled

Hey, JS experts.

Let’s say I have a form with 4 checkbox input elements. I’d like to have items 2-3 disabled unless/until #1 is checked. I figured I could have an `onchange` event in #1 to call a function that would check it’s status, and based on whether or not it’s selected, change the other 3 to enabled/disabled as applicable.

Assuming that makes sense (I’m open to better ways!), is there some naming convention or such I can use on the other 3 input elements so I can enable/disable them with one command, or would I have to use a separate change command for each?

@cootheadSep 09.2022 — Hi there NogDog,

I thought that I might drop a CSS solution in before

the JavaScript gurus pop their proboscises in...

&lt;form action="#"&gt;
&lt;label for="cb1"&gt;option 1&lt;/label&gt;&lt;input id ="cb1" type="checkbox"&gt;&lt;br&gt;
&lt;label for="cb2"&gt;option 2&lt;/label&gt;&lt;input id ="cb2" type="checkbox"&gt;&lt;br&gt;
&lt;label for="cb3"&gt;option 3&lt;/label&gt;&lt;input id ="cb3" type="checkbox"&gt;&lt;br&gt;
&lt;label for="cb4"&gt;option 4&lt;/label&gt;&lt;input id ="cb4" type="checkbox"&gt;&lt;br&gt;
&lt;input type ="reset"&gt;

</i> #cb2, label[for="cb2"],
#cb3, label[for="cb3"]{
pointer-events: none;
opacity: 0.5;
#cb1:checked ~ #cb2,
#cb1:checked ~ label[for="cb2"],
#cb1:checked ~ #cb3,
#cb1:checked ~ label[for="cb3"] {
pointer-events: auto;
opacity: 1;

Looks like magic. :) I'll give it a try at some point today and see what it does. 👍️

@NogDogauthorSep 09.2022 — Couldn't get that to entirely work for me (probably user error), but I kludged this JavaScript together that seems to do the trick, even if kind of ugly. 🤷

Well...crap...can't post my code here, and it's not important enough that I'm going to go post it on jfiddle or such. :(

I am trembling in anticipation.
