Trigger an event on `click` and `enter`

Question

I have a searchbox on my site that. Currently, users must click the submit button next to the box to search via jquery\'s post. I would like to let users also press enter

Answer 1

$('#usersSearch').keyup(function() { // handle keyup event on search input field

    var key = e.which || e.keyCode;  // store browser agnostic keycode

    if(key == 13) 
        $(this).closest('form').submit(); // submit parent form
}
