WordPress Comments jQuery Doesn’t submit

Original Poster’s answer in comments also worked for me, will share it here so this can have a solution.

Replace:

 $('form').submit(); 

With:

 $('form').unbind('submit'); $('#submit').click();

I used this to submit comments with JQuery with the ENTER key rather than clicking the button:

jQuery(document).ready(function($) {
$('#comment').keydown(function(event) {
    if (event.keyCode == 13) {//capture ENTER Key 
       $('form').unbind('submit'); $('#submit').click();
        return false;
       }
    });
});
