JQuery Event for when user presses enter?

Question

What's the simplest way to have a function called whenever the user hits enter after typing in a textbox?

Answer 1

You'll need to listen for the keypress event. It's probably easiest to do this with delegate:

$(document.body).delegate('input:text', 'keypress', function(e) {
    if (e.which === 13) { // if is enter
        e.preventDefault(); // don't submit form

        // do what you want here
    }
});

Answer 2

<textarea id="text"></textarea>

$('#text').keydown(function(e){
    if (e.keyCode == 13) {
        alert('Enter was pressed.');
    }
});
