Possible to do an OR binding with 'enter' and 'change' using jQuery?

On my page there are ht开发者_JAVA技巧ml inputs (type = text) that I'm binding to with jQuery. When the user presses the enter key or leaves the textbox after changing a value, I want to submit it (using ajax).

I created an "enter" event since jQuery doesn't supply one. I actually got it from a post here. It looks like this:

$(document.body).delegate(":input","keyup",function(e){
    if(e.which == 13)
       $(this).trigger("enter");
});

And my binding is done like so (any class that has 'submit-on-enter-or-on-change'):

$('.submit-on-enter-or-on-change').bind("enter change",function(){
    submitValue(this);
)};

The problem is when the user presses the 'enter' key and the value has changed, submitValue(this) gets called twice!

Is there any way to prevent this? One submit at a time is enough for me :)

Would something like this work?

var submitted = false;

$('.submit-on-enter-or-on-change').bind("enter change",function(){

   if (submitted) return;

   submitted = true;
   submitValue(this);
)};

One workaround would be to debounce the submitValue call.

The optional third parameter of the bind() method is a boolean that (when false) stops the event from bubbling (thus the handler from getting invoked twice). Is that what you need?

Okay, the fix to my issue was to simply remove the "enter" binding and just use "change".

Apparently, IE doesn't accept the 'enter' key on a change when using it inline with html, but it DOES work when you bind via jQuery.

i.e

<input type="text" onchange="submitValue(this)" />

doesn't submit on enter key.
