Question

I have some animated graphs. It’s cool. But I need to write out the current height of the div to another div during the animation (like an analogue timer). I have the starting and the final height, too.
So, maybe a tricky method is OK, where a continuous write out is happening while the animation itself, separately. Unfortunately, I have no idea to do this neither.
Thanks!

Answer 1

Use the under-documented animate step function (demo):

$('#div1').animate({
    height: 500
}, {
    step: function(height) {
        $('#div2')
            .height(height)
            .html( parseInt(height,10) );
    },
    duration: 500,
    complete: function() {}
});
