Answer 2

I think jQuery animate is what you are looking for. Result is something like this.

Answer 3

You're looking for:

for(i = 100; i >= 0; i--)

But you could just do this slideUp:

$('someElement')
    .hide()
    .slideDown(500, function () {
        $(this).slideUp(500);
    });

The above would animate the element like you want. That code equates to roughly the following, in case you even want to do more complicated animate animations:

$('someElement')
   .hide()
   .animate({ height: '100%' }, 500, function () {
        $(this).animate({ height: 0 }, 500);
    });

Update: Here is a jsFiddle demonstration.

Answer 4

the second one should be:

for(i = 100; i >= 0; i--)

Answer 5

How about this:

for(i = 100; i >= 0; i--)

Answer 6

If you are trying to animate the height of an object then I think you want the .animate() function of jQuery:

$('.bar-elements').animate({ height : '100%' }, 1500, function () {
    $(this).animate({ height : 0 }, 1500);
});

or alternatively you can use the slideUp/slideDown functions that do this already:

$('.bar-elements').hide().slideDown(1500, function () {
    $(this).slideUp(1500);
});
