I have several selects like this:

<select id="slctDat1" name="slctDat1" class="form-select">
      <option value="1">Text1</option>
</select>

<select id="slctDat2" name="slctDat2" class="form-select">
      <option value="1">Text1</option>
</select>

I know how to select them all with

$('select[name="slctDat[]"]')

What I need the program to do is to get the selected value of the select ‘onchange’ and disabled that value on all of them so it would look something like this:

<select id="slctDat1" name="slctDat1" class="form-select">
      <option value="1" selected disabled>Text1</option>
</select>

<select id="slctDat2" name="slctDat2" class="form-select">
      <option value="1" disabled>Text1</option>
</select>
