confirm redirects but alert doesnt

[vineet]

hi all

i am calling one function after another.

The below code shows a confirmation box and redirects to yahoo.com

<script type="text/javascript">
function todo(){
window.location="http://www.yahoo.com";
}
function conf(){
if(confirm("do you want to exit"))
{
todo();
}
}
</script>

Now instead of confirmation box if i show an alert box then the redirect doesnt works. why.

<script type="text/javascript">
function todo(){
window.location="http://www.yahoo.com";
}
function conf(){
if(alert("you are now going to exit"))
{
todo();
}
}

alert returns undefined (i.e. nothing) and undefined == false.
