I understand what you have written below is same as getting value using
$("counter").innerHTML
var myajax = new
Ajax.PeriodicalUpdater("counter","http://[...]&rndtext=0";, [...]
But, my question is how to increment it. I want to increment the value
in "counter" element by 1 every time this updater runs....
OK, I guess you mean "how to change rndtext's value after each update?"
Use "onSuccess" option to bind a function that will do that.
Here is an example:
function PeriodicUpdater() {
var cnt = $('counter');
cnt._updater = new Ajax.PeriodicalUpdater(
cnt,
'http://testserver/phanites.nsf/AJAXAgent',
{
frequency: 4,
decay: 2,
parameters: {
OpenAgent: '',
rndtext: parseInt(cnt.innerHTML) || 0
},
onFailure: function(xhr) { alert("Error"); },
onSuccess: function () {
this._updater.options.parameters.rndtext++;
}.bind(cnt)
}
);
}
cheers
