Ajax requests are by definition asynchronous. You must use alert your
value from *inside* your callback, like so:
function JSON_REQUEST()
{
new Ajax.Request('process.php?mode=json', { method:'get', onSuccess:
function(transport){
alert(transport.headerJSON)}
});
}
Also I suggest you drop using the second argument to your callback,
and use the new headerJSON property instead, as the former has been
deprecated.
