jQuery - is it bad to have multiple $(document).ready(function() {});

Is it bad to have multiple $(document).ready(function() {}); on your page? I have a website where I load different things at different times. I fire off those partial postback functions inside $(document).ready() but i have about 4 or 5 on the page at once. Is this a bad practice? Specifically, will it cause any performance issues?

The answer is no! You can litter them as much as you want (note the word litter). They just become a queue of events that are called when the ready event is triggered.

The answer is actually "Yes it deters performance":
