要完成此效果把如下代码加入到区域中 <script language="JavaScript1.2"> var stringcolor="white" var ballsrc="http://www.jojoo.net/logo.gif" if (document.all&&window.print){ document.write('') ddx=0;ddy=0;PX=0;PY=0;xm=0;ym=0 OmW=Om.width/2;OmH=Om.height/2 } function Ouille(){ x=Math.round(PX+=(ddx+=((xm-PX-ddx)*3)/100)) y=Math.round(PY+=(ddy+=((ym-PY-ddy)*3-300)/100)) Om.style.left=x-OmW Om.style.top=y-OmH elastoc.to=x+","+y elastoc.strokecolor=stringcolor setTimeout("Ouille()",1) } function momouse(){ xm=window.event.x+5 ym=window.event.y+document.body.scrollTop+15 elastoc.from=xm+","+ym } if(document.all&&window.print){ code=""} else { code=""} if(document.all&&window.print){ document.body.insertAdjacentHTML("afterBegin",code) document.onmousemove=momouse Ouille() } </script>
