Question

I have a form which needs javascript to be enabled for validation, is there a way to disable submit button when javascript is disabled and warn user to enable it first ?

Answer 1

Disable it by default and use JavaScript to enable it.

<input type="submit" value="Submit" id="submitBtn" disabled />

<script type="text/javascript">
var _onload = window.onload || function()
{
  document.getElementById('submitBtn').disabled = false;
}

_onload();
</script>

That way, if JavaScript is disabled then the button will also remain disabled.

jQuery version:

<script type="text/javascript">
$(function(){
  $('#submitBtn').attr('disabled', false);
});
</script>
