jquery - Pressing enter submits form but breaks accessibility -

i have html form. i'm intercepting activation of submit button need run javascript rather normal form submission.

i added javascript both pressing enter , clicking submit button activates form (i think normal practice). breaks accessibility. when user tabs button or link outside form , presses enter, button has focus aught activate. doesnt - form button gets activated instead. standard way of dealing (i feeling i'm missing fundamental here)?

simplified version of i'm using capture hitting enter (jquery)....

    $("form").bind("keydown", function(e){             if (e.which == 13) {                 e.currenttarget.blur();                 $("button").click();                 return false;             }          }); 

intercept submit() action instead, , use event.preventdefault() cancel immediately:

$('form').on('submit',function(e) {     e.preventdefault();     // more code });
