Hi,
you can do something like a periodical updater:
<div id="myid"></div>
<script type="text/javascript">
var periodicalUpdater = Class.create();
Object.extend(periodicalUpdater.prototype, {
callback: function(res) {
if(res.value != null) {
this.ele.innerHTML = res.value;
}
setTimeout(this.update.bind(this), this.interval);
},
update: function() {
MyNamespace.MyClass.MyMethod(this.callback.bind(this));
},
initialize: function(id, interval) {
this.ele = $(id);
this.interval = (interval != null ? interval : 1000);
setTimeout(this.update.bind(this), this.interval);
}
}, false);
var x = new periodicalUpdater("myid", 2000);
</script>
The example above will update the myid DIV every 2000 msec. The next
step would be to change the class to add an argument for the
constructor that will hold the AjaxMethod name, then you can use this
for any method. Or add a new property that will stop the automatic
refresh, then you can call "x.update()" manual.
I hope this example will help you...!
Regards,
Michael
