Auto submit on page load

I use the Divi theme with a CF7 module. I have a need when a page is loaded that it automatically triggers the submit button to send me a email. Hunting on the internet I found this code

<script type="text/javascript">
jQuery(document).ready(function(){
     jQuery("#wpcf7-f3857-o1 form").submit();
});
</script>

where wpcf7-f3857-o1 is the CSS id of the CF7

When the page is activated a loop occurs where its attempting to press the submit button with a message saying its unsuccessful, others using this code have had the same problem. I am unable to find an actual solution to automatically trigger the submit button on page load.

Has anyone got any ideas? Thankyou for any assistance.
