Come on, MorningZ, there's no need for insults.
But yes, 5000 of those will be pretty slow - and that's before you even
execute the code inside those functions. How slow? It's easy to test. The
ready functions are run in the order that the $() functions are called. So
simply do this in a test page:
var t1 = +new Date;
$(function(){});
// ... Repeat above line 5000 times
$(function() {
var t2 = +new Date;
alert( (t2-t1)/1000 + ' seconds' );
});
You can easily generate that file by hand in a text editor. You don't have
to do 5000 pastes. Start with 10 of them, copy that block and paste it 10
times so you have 100, copy *that* block and paste it 10 times so you have
1000, copy that and five more pastes and you're done.
Test it in IE6 (!), and if you're on your usual development machine, triple
the time from the alert to take into account the slower machines that your
visitors will have (think a slow laptop running on battery). If you don't
have IE6, try it in IE7 and as a rough guess, multiply your observed time by
six (triple for the slow machines, double again for IE6).
Mind if I ask: why do you need 5000 of these? There probably is a better way
to do it.
