光标放上去小图变大的图片横向轮转

那弹性的还真难做,试了一个下午没做出来.............你看看这样行不:

//图片总数:
total = 7;
//间距:
d = 25;
//图片宽:
w = 100;
//总长:
W = total*(w+d);
//图片变大变小的速度:
dScale = 10;
//在场景中加入图片:
for (i=1; i<=total; i++) {
 this.attachMovie("pic", "pic"+i, i, {_x:i*(w+d)-W/2});
 pic = this["pic"+i];
 pic.gotoAndStop(i);
 //鼠标放在图片上:
 pic.onRollOver = function() {
  this.onEnterFrame = function() {
   //变大:
   this._xscale = this._yscale += dScale;
   //以该图片为基准调整距离:
   pic0 = this;
   distance(pic0);
   //如果大到一定程度就停止变大:
   if (this._xscale>200) {
    this._xscale = this._yscale=200;
    delete this.onEnterFrame;
    pic0 = head;
   }
  };
 };
 //鼠标离开图片:
 pic.onRollOut = function() {
  this.onEnterFrame = function() {
   //变小:
   this._xscale = this._yscale -= dScale;
   //以该图片为基准调整距离:
   pic0 = this;
   distance(pic0);
   //如果小到一定程度就停止变小:
   if (this._xscale<100) {
    this._xscale = this._yscale=100;
    delete this.onEnterFrame;
    pic0 = head;
   }
  };
 };
 //用来建个类似双向链表的东东:
 pic.prevPic = prevPic;
 prevPic.nextPic = pic;
 prevPic = pic;
}
//形成环链:
this.pic1.prevPic = this["pic"+total];
this["pic"+total].nextPic = this.pic1;
//
head = this.pic1;
tail = this["pic"+total];
//以链头为基准(用来调整距离):
pic0 = head;
//
function onEnterFrame() {
 if (head._x<-W/2) {
  head._x = tail._x+(tail._width+head._width)/2+d;
  tail = head;
  head = head.nextPic;
  pic0 = head;
 } else if (tail._x>W/2) {
  tail._x = head._x-(tail._width+head._width)/2-d;
  head = tail;
  tail = tail.prevPic;
  pic0 = head;
 }
 head._x += -_xmouse/20;
 distance(pic0);
}
//--------------------------------------------------------------------------------------------
//以pic0为基准调整各幅画间距离的函数:
function distance(pic0) {
 var pic = pic0;
 while (pic != head) {
  pic.prevPic._x = pic._x-(pic._width+pic.prevPic._width)/2-d;
  pic = pic.prevPic;
 }
 pic = pic0;
 while (pic != tail) {
  pic.nextPic._x = pic._x+(pic._width+pic.nextPic._width)/2+d;
  pic = pic.nextPic;
 }
}
