jQuery trigger() and stopPropagation() on keydown event

问题

I am having a difficult time with keydown and stop propagation

i do not want my page to refresh, i have tried every which way i can think of, my current code is

 <script>
 $(document).ready(function() {
 var e = jQuery.event( 'keydown', { which: $.ui.keyCode.ENTER } );

 $('#id_number').trigger(e, function(event){
event.preventDefault();
event.stopPropagation();
});

 });
 </script>

any idea on what i am doing wrong here? I thought that the event was called correctly, i have jquery and jquery ui linked correctly and receive no console errors

UPDATE well it was working, now im getting Property 'event' of object function (a,b){return new e.fn.init(a,b,h)} is not a function error on the below code

 $(document).ready(function() {
 var e = jQuery.event( 'keydown', { which: $.ui.keyCode.ENTER } , function(event){
  event.preventDefault();
  event.stopPropagation();
}); 

 $('#id_number').trigger(e);

 });

UPDATE #2 - fixed

things I learned

1. trigger() not needed in the document(ready)
2. getting $.ui.keyCode to work was difficult (at least for me)
3. always see what other functions are attached to the input (onblur, onfocus, ect) aka doh

rewrote it to this, works perfectly fine

 $(document).ready(function() {
    $('#id_number').keydown(OnKeyDown);
 });    

function OnKeyDown(e){
var code = (e.keyCode ? e.keyCode : e.which); //to support both methods
if(code == 13) { //the Enter keycode

    //my actions
 return false;
 }
}

回答1:

The code to stop the default action must go to the element that the event applies to..

$('#id_number').keydown(function(event){
  event.preventDefault();
  event.stopPropagation();
});

The .trigger() second argument is for extraParameters
