onClick with CTRL button

Question

I have an issue with the button clicking with Ctrl key. The form is being posted twice. (on the same tab and on the new tab)

I don't want to go to new tab (in order to avoid twice submission)

I tried return false;

onClick="document.form[0].submit(); return false;"

but no success.

Thanks for any help.

Here is jsFiddle

Answer 1

try next:

1. replace document.form[0] by document.forms[0];
2. add name attribute for your input tag;
3. change your button type attribute to button

Try this:

$('#submit').on('click',function(e){
  e.preventDefault();
  document.form[0].submit();
});
