javascript实现的一个图片转移效果_图象特效

应网友要求修改一个图片转移效果 一个比较漂亮的效果，只是在增加图片效果时有些麻烦。今天应网友的要求，对 JS 进行了更改。使大家在对图片添加删除更加容易。在这里主要对以下几点详细说明一下。
var firstnum = 1;
var secnum = 2; 
var tounum=1; 
这三个变量分别作用是传入图片 ID 变量。以及保存当前图片 ID 便于操作！ 相信大家都会很容易的修改成自己想要的效果 ! 
代码如下:

<style type="text/css"> #mainid{position:absolute;right:5px;top:10px;height:435px;width:650px;overflow:hidden;background:#fff;left: 400px;border: 3px solid #666666;} .imgbox{position:absolute; left:35px; margin-top:20px; top:105px; z-index:90; width:100px;height:100px;background:#ffffff} .moveimgbox{position:absolute; left:700px; margin-top:20px; top:105px; z-index:90; width:100px;height:100px;background:#ffffff} </style> <script> var ticked=0; var okayToGo = true; var currentCreature = 1; var forwardBackward = 1; var firstnum = 1; var secnum = 2; var tounum=1; function moveItem(firstnum,secnum){ if(okayToGo&& firstnum != secnum){ tounum=firstnum; document.getElementById("y"+firstnum).style.zIndex = 50+10*forwardBackward; document.getElementById("y"+secnum).style.zIndex = 50+20*forwardBackward; startTheMove =window.setInterval(function(){rightOrLeft(firstnum,secnum)},20); } } function rightOrLeft(firstnum,secnum) { if (ticked == 1020) { window.clearInterval(startTheMove); ticked = 0; forwardBackward = 1; okayToGo = true; } else { okayToGo = false; thisAngle = (Math.PI/2)*(ticked/1000); document.getElementById("y"+firstnum).style.left = " "+(735-Math.sin(thisAngle)*700)+"px"; document.getElementById("y"+firstnum).style.top = " "+(105-(forwardBackward*Math.cos(thisAngle)*55))+"px"; document.getElementById("y"+secnum).style.left = " "+(735-Math.sin(thisAngle+Math.PI/2)*700)+"px"; document.getElementById("y"+secnum).style.top = " "+(105-(forwardBackward*Math.cos(thisAngle+Math.PI/2)*55))+"px"; ticked += 20; } } </script> <a href="javascript:moveItem(1,tounum);"><img src="http://www.szrgb.net/text/moveimg/images/1.GIF" style="max-width:90%" style="max-width:90%" alt="javascript实现的一个图片转移效果_图象特效" ></a> <a href="javascript:moveItem(2,tounum);"><img src="http://www.szrgb.net/text/moveimg/images/2.JPG" style="max-width:90%" style="max-width:90%" alt="javascript实现的一个图片转移效果_图象特效" ></a> <a href="javascript:moveItem(3,tounum);"><img src="http://www.szrgb.net/text/moveimg/images/3.JPG" style="max-width:90%" style="max-width:90%" alt="javascript实现的一个图片转移效果_图象特效" ></a> <a href="javascript:moveItem(4,tounum);"><img src="http://www.szrgb.net/text/moveimg/images/4.jpg" style="max-width:90%" style="max-width:90%" alt="javascript实现的一个图片转移效果_图象特效" ></a> <div align="right" id="mainid"> <div id="y1" class="imgbox"><img src="http://www.szrgb.net/text/moveimg/images/1.GIF" alt="javascript实现的一个图片转移效果_图象特效" ></div> <div id="y2" class="moveimgbox"><img src="http://www.szrgb.net/text/moveimg/images/2.JPG" style="max-width:90%" style="max-width:90%" alt="javascript实现的一个图片转移效果_图象特效" ></div> <div id="y3" class="moveimgbox"><img src="http://www.szrgb.net/text/moveimg/images/3.JPG" style="max-width:90%" style="max-width:90%" alt="javascript实现的一个图片转移效果_图象特效" ></div> <div id="y4" class="moveimgbox"><img src="http://www.szrgb.net/text/moveimg/images/4.jpg" style="max-width:90%" style="max-width:90%" alt="javascript实现的一个图片转移效果_图象特效" ></div> </div>
