   $(document).ready(function(){
  $("#payuForm").submit();
     });
 </script>

Answer 1

Create a hidden submit type button(i.e. display:none;), after page load through jquery click on it automatically(i.e. $('#submit').click() ), Create a function for clicking on submit button, call it after page loads...

EDIT: HTML:

<form ...>
...
<input type="submit" id="submit" style="display:none;" />
</form>

Javascript:

function submit_click(){
 $("#submit").click();
}

Now, when your auto form populating data's function called, call this function in last line submit_click();
