I would write some code like this (not tested):
function dateChecker() {
this.firstValue = null;
this.secondValue = null;
this.ondata = null; // used to get notified if data has been received
}
Object.extend(dateChecker.prototype, {
callback: function(res) {
if(res != null && res.value != null) {
this.firstValue = res.Tables[0].Rows[0].one;
this.secondValue = res.Tables[0].Rows[0].second;
}
if(typeof this.ondata == "function") {
setTimeout(this.ondata.bind(this), 1);
}
},
requestDates: function(param1, param2) {
// use arguments only if needed
Namespace.Class.AjaxMethod(param1, param2, this.callback.bind(this));
}
});
So, what you can do now is to create a new instance of this simple class:
var x = new dateChecker();
Now, you have to write your code that should be invoked when the
result is there, always think on asyncronous calls!!
x.oninit = function() {
alert(this.firstValue);
}
To start the request you will write this line:
x.requestDates(param1, param2);
If you need the value later again you can use x.firstValue or x.secondValue.
