The code below works fine without the use of the FORM tag.
But after I add the FORM tag, the code does not work anymore.
My code:
function ismcstop() {
var chkNo = document.getElementById("radio2_ismcstop");
var mcnostopreason = document.getElementById("mcnostopreason");
mcnostopreason.disabled = chkNo.checked ? false : true;
if (!mcnostopreason.disabled) {
mcnostopreason.focus();
}
}
<form action="" method="post">
<div class="row">
<div class="col-4">
<div class="container">
<label for="ismcstop">Machine Stop?</label>
<div class="form-check-inline">
<label class="form-check-label" for="radio1_ismcstop">
<input type="radio" class="form-check-input" id="radio1_ismcstop" name="ismcstop" onclick="ismcstop()" value="Yes">Yes
</label>
</div>
<div class="form-check-inline">
<label class="form-check-label" for="radio2_ismcstop">
<input type="radio" class="form-check-input" id="radio2_ismcstop" name="ismcstop" onclick="ismcstop()" value="No">No
</label>
</div>
</div>
</div>
<div class="col-2">
<label for="mcnostopreason">If No, Reason:</label>
</div>
<div class="col-6">
<input class="inputstyle-100" id="mcnostopreason" name="" value="" disabled>
</div>
</div><br>
</form>
