Question

i usually do

$('#load').show();
$(document).ready(function(){
    $('#load').hide();
});

where <div id="load"> has just a animated gif

but i was thinking of improve a little bit and show a progressbar

having

<div id="load"><div id="done"></div></div>

so i could, in a timeout (i guess)

var percent_done = how_do_i_figure_out(); /*  here is where i need help */
$('#done').width(percent_done);

Answer 1

It can’t be done!

You have no access to elements not rendered yet, so how would you know what is missing?!
