Whats wrong with this code?

This issue is driving me nuts and not able to figure out whats wrong.
I've this code in my firefox extension. Firefox always hangs and
reports the script is busy.

if I introduce a break statement in the for(; loop below, then
no issue.

Any help would be appreciated!

function getStuff()
{
try
{
httpReq = new XMLHttpRequest();


httpReq.onreadystatechange = function(evt)
{
if (httpReq.readyState == 4)
{
if (httpReq.status == 200)
{
getList(httpReq.responseText);
}
}
}


httpReq.open("GET", "http://www.mysite.com", true);
httpReq.send(null);
}catch(ex)
{
Components.utils.reportError(ex);
}
}


function getList(htmlText)
{
for(;
{
}
}

loop.

What is your question?
I am afraid I cannot follow your line of thought at all. :-/

Since httpReq is global, every time you getStuff() you'll destroy any
other AJAX call that may be executing. Is that the desired effect?

function getList(htmlText)
{
for(;
{
}
}

Well, this is pretty obvious xD

snap

function getList(htmlText)
{
for(;
{
}

}
The above is never ending loop, this is an equivalent of telling your

CPU to do nothing (NOP) but be BUSY all the time...

Please do (post the correct code), because the posted code does
EXACTLY what you can expect it to do - hangs you machine...
