AS3 setTimeOut，setInterval，Timer 的区别和用法

AS3 setTimeOut，setInterval，Timer都是起定时作用，但用法有所不同。
1、setTimeOut：设置超时时间，只会执行一次！
参数说明：
setTimeOut(函数名,延迟时间,参数);
用法：
package {
import flash.display.Sprite;
import flash.utils.*;

public class SetTimeoutExample extends Sprite {
private var delay:Number = 1000; // delay before calling myDelayedFunction
public function SetTimeoutExample() {
var intervalId:uint = setTimeout(myDelayedFunction, delay, "Hello", "World");
}
public function myDelayedFunction():void {
trace(arguments[0] + " " + arguments[1]);
}
public function clearTimeout():void {
if(intervalId>0) {
clearTimeout(intervalId);
}
}
}
}

2、setInterval：设置一个间隔时间，间隔多久会触发一次！除非 remove，否则会永久执行下去！
参数说明：
setInterval(函数名,延迟时间,参数);
用法：
package {
import flash.display.Sprite; import flash.utils.*;
public class SetIntervalExample extends Sprite {
private var intervalDuration:Number = 1000; // duration between intervals, in milliseconds
private var intervalId:uint;
private var counter:uint = 0;
private var stopCount:uint = 3;
public function SetIntervalExample() {
intervalId = setInterval(myRepeatingFunction, intervalDuration, "Hello", "World");
}
public function myRepeatingFunction():void {
trace(arguments[0] + " " + arguments[1]);
counter++;
if(counter == stopCount) {
trace("Clearing Interval");
clearInterval(intervalId);
}
}
}
}

3、Timer：设置一个间隔时间，有次数限制，只执行制定次数！
参数说明：
Timer(延迟时间，执行次数);
用法：
package {
import flash.utils.Timer;
import flash.events.TimerEvent;
import flash.display.Sprite;
public class TimerExample extends Sprite {
public function TimerExample() {
var myTimer:Timer= new Timer(1000, 2);
myTimer.addEventListener("Timer", timerHandler);
myTimer.start();
}
public function timerHandler(event:TimerEvent):void {
trace("timerHandler: " + event);
}
}
}

setTimeOut：设置超时时间，只会执行一次！
setInterval：设置一个间隔时间，间隔多久会触发一次！除非 remove，否则会永久执行下去！
Timer：设置一个间隔时间，有次数限制，只执行制定次数！
参数说明：
setTimeOut(函数名,延迟时间,参数);
setInterval(函数名,延迟时间,参数);
Timer(延迟时间，执行次数);
举例：
1.setTimeOut
package {
import flash.display.Sprite;
import flash.utils.*;
public class SetTimeoutExample extends Sprite {
private var delay:Number = 1000; // delay before calling myDelayedFunction
public function SetTimeoutExample() {
var intervalId:uint = setTimeout(myDelayedFunction, delay, "Hello", "World");
}
public function myDelayedFunction():void {
trace(arguments[0] + " " + arguments[1]);
}
public function clearTimeout():void {
if(intervalId>0) {
clearTimeout(intervalId);
}
}
}
}

2.setInterval
package {
import flash.display.Sprite; import flash.utils.*;
public class SetIntervalExample extends Sprite {
private var intervalDuration:Number = 1000; // duration between intervals, in milliseconds
private var intervalId:uint;
private var counter:uint = 0;
private var stopCount:uint = 3;
public function SetIntervalExample() {
intervalId = setInterval(myRepeatingFunction, intervalDuration, "Hello", "World");
}
public function myRepeatingFunction():void {
trace(arguments[0] + " " + arguments[1]);
counter++;
if(counter == stopCount) {
trace("Clearing Interval");
clearInterval(intervalId);
}
}
}
}

3.Timer
package {
import flash.utils.Timer;
import flash.events.TimerEvent;
import flash.display.Sprite;
public class TimerExample extends Sprite {
public function TimerExample() {
var myTimer:Timer= new Timer(1000, 2);
myTimer.addEventListener("Timer", timerHandler);
myTimer.start();
}
public function timerHandler(event:TimerEvent):void {
trace("timerHandler: " + event);
}
}
}

Timer：设置一个间隔时间，有次数限制，只执行制定次数！
参数说明：
setTimeOut(函数名,延迟时间,参数);

}
}
}

clearInterval(intervalId);
}
}
}

希望对你有帮助！有帮助望采纳！

是flash as3.0吗？这个就是定时器吧，隔多少秒刷新
