onsubmit not working

[Johnn]

I have been wondering for hours why this snippet of code does not work at all. 

Please let me understand what was lacking or wrong in my code. Thanks

 

<script>
    document.getElementById("caspioform").onsubmit=sbmt;

    function sbmt()
    {
        alert('Submitted');
    }
</script>

Hi @Johnn,

You can use FormSubmitted event handler. I saw it in the howto article: https://howto.caspio.com/datapages/ajax-loading/

<script type="text/javascript">
document.addEventListener('FormSubmitted', function(event) {
	alert('Submitted');
});
</script>

Thank you!

Works perfectly!

Please help on this another issue. 

I don't know why but the code below doesn't seem to work. 

<script>
document.getElementById("Submit").style.display = "none";
</script>
