Including jQuery again overwrites already registered document-ready events

[Jörn]

By including jQuery again, all document-ready events are lost. If you can see the text below, the problem still exists. This problem exists in enviroments, where the page author controls only a part of the document, like Portlets (Java JSR 168). While it is possible workaround this by only including jQuery when it is not loaded yet, it would be much more convienent to have that built into jQuery itself.

It might by suffice to include a check for an existing jQuery variable at the start of the script. Something like:

if(typeof window.jQuery == "undefined") {
// rest of the jQuery code
}

I'm no fan of wrapping the code into one monster if. Is there some kind of return oder quit/exit inside a single javascript file?

Fixed in SVN, tested in FF 1.5.0.6, IE 5.5 SP2 and IE 6, Opera 9.01, Safari 1.3.x.
