Update a DIV prior to long running section

[Richard A. DeVenezia]

I have a function that will update a divs innerHTML with the result of a
long running loop. I would like to update the div prior to running the loop
so the person knows it is doing something.
i.e.
function doit () {
mydiv.innerHTML = 'working...';
.... long running loop generates html in variable s
mydiv.innerHTML = s
}

Doing things this way I don't see working..., just the results of the loop
after several seconds.
How might I update mydiv prior to running the loop ?

Thanks.

Unless you have mydiv defined elsewhere as a reference to an element,
then the above code is IE only.

.... long running loop generates html in variable s
mydiv.innerHTML = s
}

function doit(){
document.getElementById('mydiv').innerHTML = 'working......';
myTimer = window.setTimeout('realFunction()',1000);
}

function realFunction(){
//long running loop that generates s
document.getElementById('mydiv').innerHTML = s;
}
