Thanks Fred.
I've followed the second option and it worked. Below is my code, in
case someone will find it helpful:
var updateCounter = 0;
function createUpdater(freq)
{
updater = new Ajax.PeriodicalUpdater("ajaxDIV", "Tickets.jsp", {
frequency: freq,
evalScripts: true,
onCreate: function()
{
// change update frequency when data size changes, and
after the initial load
if (updateCounter != 0 && dataSize != this.frequency / 5)
{
alert("data size changed. frequency new: " + dataSize
* 5 + " old: " + this.frequency)
updateCounter = 0;
updater = createUpdater(dataSize * 5);
this.updater.stop();
}
},
onSuccess: function()
{
updateCounter ++;
},
parameters: Form.serialize($("form"))
}
)
;
return updater;
}
