要完成此效果需要两个步骤 第一步：把如下代码加入到<head>区域中 <script> var dragswitch=0 var nsx var nsy var nstemp function drag_dropns(name){ temp=eval(name) temp.captureEvents(Event.MOUSEDOWN | Event.MOUSEUP) temp.onmousedown=gons temp.onmousemove=dragns temp.onmouseup=stopns } function gons(e){ temp.captureEvents(Event.MOUSEMOVE) nsx=e.x nsy=e.y } function dragns(e){ if (dragswitch==1){ temp.moveBy(e.x-nsx,e.y-nsy) return false } } function stopns(){ temp.releaseEvents(Event.MOUSEMOVE) } var dragapproved=false function drag_dropie(){ if (dragapproved==true){ document.all.showimage.style.pixelLeft=tempx+event.clientX-iex document.all.showimage.style.pixelTop=tempy+event.clientY-iey return false } } function initializedragie(){ iex=event.clientX iey=event.clientY tempx=showimage.style.pixelLeft tempy=showimage.style.pixelTop dragapproved=true document.onmousemove=drag_dropie } if (document.all){ document.onmouseup=new Function("dragapproved=false") } function hidebox(){ if (document.all) showimage.style.visibility="hidden" else if (document.layers) document.showimage.visibility="hide" } </script> 第二步：把如下代码加入到<body>区域中 <div id="showimage" style="position:absolute;width:250px;left:250;top:250"> <table border="0" width="250" bgcolor="#33ff33 cellspacing="0" cellpadding="2"> <tr> <td width="100%"><table border="0" width="100%" cellspacing="0" cellpadding="0" height="36"> <tr> <td onMousedown="initializedragie()" style="cursor:hand" width="100%"><ilayer width="100%" onSelectStart="return false"><layer width="100%" onMouseover="dragswitch=1;drag_dropns(showimage)" onMouseout="dragswitch=0"><center><font face="Verdana" color="#FFFFFF"><strong><small>Typhoon Start</small></strong></font></center></layer></ilayer></td> <td style="cursor:hand"><a href="#" onClick="hidebox();return false"><img src="dot.gif" width="16" height="14" border=0></a></td> </tr> <tr> <td width="100%" bgcolor="#FFFFFF" style="padding:4px" colspan="2"> <small><strong><center><font face="Verdana">点“X”关闭小窗口</font></center></strong></small><small><font face="Verdana"></font></small> </td> </tr> </table> </td> </tr> </table> </div>
