Flash判断双击之记时法

下面是代码：

class devil.com.btn.original.DoubleClick {

private var _clickedObject:Object;

private var _ID:Number;

private var _delayTime:Number = 200;

private var _count:Number = 0;

public function set delayTime(delay:Number):Void {
_delayTime = delay;
}
public function get delayTime():Number {
return _delayTime;
}

public function DoubleClick(delayTime:Number) {
this._delayTime = delayTime;
}

public function click(obj:Object) {
if (this._clickedObject == undefined) {
_clickedObject = obj;
}
if (_count == 0) {
//first click
timerStart();
_count = 1;
} else {
this._clickedObject.onDoubleClick();
//双击
_count = 0;
}
}

private function timerStart():Void {
clearInterval(_ID);
_ID = setInterval(this, "timerStop", _delayTime);
}

private function timerStop():Void {
clearInterval(_ID);
if (_count == 1) {
_clickedObject.onClick();
//单击
_count = 0;
}
}
}

下面是用法：

import devil.com.btn.original.DoubleClick;
var b:DoubleClick = new DoubleClick(200);
b.onClick = function() {
//单击要执行的函数
trace("单击")
};
b.onDoubleClick = function() {
//单击要执行的函数
trace("单击")
};
b.onDoubleClick=function(){
//双击
trace("双击")
}
b.onRelease=function (){
_root.a.click(this)}
