Question

i want to protect my inputs from brut force hacks
so i made some validations for my inputs .. and i want them to work on focus event and
focusout event too ! is there any elegant way to do it, other than this :

$(this).focus(function(){
// excute my code
});

and then

$(this).focusout(function(){
// excute the same code !
});

i want do this for too many inputs .. and i don’t want do the same work twice for (focus, and focusout) to avoid the extra load of the page !

While I disagree with the premise of this question (you can’t prevent brute-force attacks via client-side code) you can simplify your code by passing both events as a space separated string to on:

$(this).on('focus focusout', function() {
    // excute my code
});

If you’re using an older version of jQuery, use bind instead:

$(this).bind('focus focusout', function() {
    // excute my code
});
