Example 4: The following example shows how to use setInterval() correctly from an
ActionScript 2.0 custom class. Note that similar to previous examples,
this is passed to the
setInterval() function to ensure that the called method is executed within the correct
scope.
class CustomClass {
private var intervalId:Number;
private var count:Number = 0;
private var maxCount:Number = 10;
private var duration:Number = 20;
public function CustomClass():Void {
beginInterval();
}
private function beginInterval():Void {
if(intervalId != null) {
trace("clearInterval");
clearInterval(intervalId);
}
intervalId = setInterval(this, "executeCallback", duration);
}
public function executeCallback():Void {
trace("executeCallback intervalId: " + intervalId + " count: " + count);
if(count >= maxCount) {
clearInterval(intervalId);
}
