Answer 1

Use on() and off() to turn the click function on/off :

$('.ele').on('click', animateEle);

function animateEle(e) {
    $('.ele').stop().animate({'top':'0px'},2000);
    $(e.target).off('click').stop().animate({'top':'100px'},4000, function() {
        $(e.target).on('click', animateEle);
    });
}​

You can try this:

var exec_a1 = true, exec_a2 = true;
$('.ele').click(function() {
    if (exec_a1 && exec_a2) {
        exec_a1 = false;
        exec_a2 = false;

        $('.ele').stop().animate({'top': '0px'}, 2000, function() {
            exec_a1 = true;
        });
        $(this).stop().animate({'top': '100px'}, 4000, function() {
            exec_a2 = true;
        });
    }
    return false;
});
