JQuery Event Keypress: Which key was pressed?

Question

JQuery Event Keypress: Which key was pressed?

With jQuery, how do I find out which key was pressed when I bind to the keypress event?

$('#searchbox input').bind('keypress', function(e) {});

I want to trigger a submit when ENTER is pressed.

Even though I found the (or better: one) answer myself, there seems to be some room for variation ;)

Is there a difference between keyCode and which - especially if I'm just looking for ENTER, which will never be a unicode key?

Do some browsers provide one property and others provide the other one?

Try this

$('#searchbox input').bind('keypress', function(e) {

    if(e.keyCode==13){

        // Enter pressed... do anything here...

    }

});

If you are using jQuery UI you have translations for common key codes. In ui/ui/ui.core.js:



$.ui.keyCode = { 

    ...

    ENTER: 13, 

    ...

};

There's also some translations in tests/simulate/jquery.simulate.js but I could not find any in the core JS library. Mind you, I merely grep'ed the sources. Maybe there is some other way to get rid of these magic numbers.

You can also make use of String.charCodeAt and .fromCharCode:



>>> String.charCodeAt('\r') == 13

true

>>> String.fromCharCode(13) == '\r'

true
