Perhaps turn that logic around: Rather than giving the value back to
the PE and letting it decide whether to stop, you could pass the PE to
the request function and have the request decide whether to stop the
PE:
em = function(url, pe)
{
var percent;
new Ajax.Request(url,
{
method: 'get',
onSuccess: function(transport)
{
var Bar = $('emBar');
percent = transport.responseText;
Bar.setStyle({ width: percent + '%' });
if (parseInt(percent) > LIMIT)
{
pe.stop();
}
}
});
}
Alternately, wrap all of this in an object where both the request and
the PE are members, and the object has a method used by the success
callback to decide whether to stop.
Or, of course, use a global. But that would be wrong. :-)
FWIW.
