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="../wydh/images/close.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>
