I am struggling to find a way to make my checkbox to either choose either one or two nor combination. What the code does currently allows one to select checkbox at a time and you can download the file format. I want to find a way that is possible if a user select neither one, two or combination of the checkbox be able to download the file format based on my given code below that have attempted to write.

What I have tried:

<div class = "custom-control custom-checkbox">
  <input type="checkbox" class ="custom-control-input" id="temperature">
    <label class = "custom-control-label" for="temperature">Temperature</label>
 <div class = "custom-control custom-checkbox">
 <input type = "checkbox" class="custom-control-input" id="illuminance">
   <label class = "custom-control-label" for = "illuminance">Illuminance</label>
 <div class ="custom-control custom-checkbox">
 <input type ="checkbox" class="custom-control-input" id="button-state">
   <label class ="custom-control-label" for = "button-state">Button-State</label>

It is unclear...
Are you looking for force valid combination of the 3 checkboxes you have?

Yes something like that

You probably better off using radio buttons... The UI will be clear to the end user... In you case you should explain (via some message) why you block certain clicks...

1 solution

This will run your if any of the checkboxes are checked

if($('temperature').is(':checked') || $('illuminance').is(':checked') || $('button-state').is(':checked')){'');
