Java script people, can you help me decode this bit of code?

document.write("<div id=_p_></div>");window.onload=function(){try{var u=document.body.getAttribute("unload");if(u)eval(u);}catch(e){}};

It looks like every time I go on the net with firefox at work it will first go to 1.2.3.0

So I was wondering what that was and typed that into the address bar. That's when I see the code above. It looks to me its gathering my info and writing it to a file. Can somebody tell me exactly what info its gathering?

Thanks
 
Two functions here:

document.write("<div id=_p_></div>") does nothing. Writes an empty <div> tag.

window.onload=function(){try{var u=document.body.getAttribute("unload");if(u)eval(u);}catch(e){}};

Retrieves the contents of the unload attribute from the <body> tag in your HTML. If there is an unload function defined, that function is then executed. The code is executed when the window is loaded.

Thanks for your help. But I still don't understand what exactly does it do? What is the unload attribute?

Yes they/we did!

And IMO idle topics hang out on page one way too long for a board with as many techie members as this one.

If assigned a value, it names a function/procedure to call when the page body is unloaded from the browser window. What actually happens depends on what the function was written to do.
