Where is that Ajax.Request object created? In a function somewhere
that gets called over and over? If so, is there any particular reason
the success handler has to be an inline function? (I don't
immediately see it referencing anything outside of itself that it
would need to be a closure, for instance.) It shouldn't be a problem
provided nothing's holding on to the function or the Ajax.Request
after it completes, but that doesn't mean that the GC is going to be
perfect in every case and in fact Firefox 2 has several known leaks
around this stuff. I'd try this:
At global (page/script) scope:
function handleUpdateSuccess(transport){
var json = transport.responseText.evalJSON();
$('statusBanner').update();
$('Month1').update(responseJSON.Month1);
$('Month1V').update(json.Month1V);
$('Month2').update(json.Month2);
$('Month2V').update(json.Month2V);
$('Month3').update(json.Month3);
$('Month3V').update(json.Month3V);
$('L1V').update(json.L1V);
$('L2V').update(json.L2V);
$('L3V').update(json.L3V);
$('Spread1').update(json.Spread1);
$('Spread1V').update(json.Spread1V);
$('Spread2').update(json.Spread2);
$('Spread2V').update(json.Spread2V);
$('Spread3').update(json.Spread3);
$('Spread3V').update(json.Spread3V);
delete json;
}
function handleUpdateFailure()
{
$('statusBanner').update("<h1>Loading</h1>");
}
And then where your request is created:
new Ajax.Request('getData?time=' + dateTime,
{
method:'get',
onSuccess: handleUpdateSuccess,
onFailure: handleUpdateFailure
});
FWIW, might make no difference, might help.
