Consider following HTML snippet:

<input type="text" value="zombie"/>
<input type="submit" />

What will be the value of attribute "value" after executing following jQuery code snippet?

$('input[type="button"]').click(function(){
        $('input[type="text"]').val('human');
});

$('input[type="text"]').val('human');

$('input[type="text"]').atrr('value','human');
