可以拖动和隐藏的层，替代弹出窗口

本脚本创建了一个图层，可以通过连接控制其显示和隐藏，并可以通过标题栏拖动，用于替代弹出窗口再好不过了！

在网页<head>区添加以下代码


<script language="JavaScript1.2">

isIE=document.all;
isNN=!document.all&&document.getElementById;
isN4=document.layers;
isHot=false;

function ddInit(e){
  topDog=isIE ? "BODY" : "HTML";
  whichDog=isIE ? document.all.theLayer : document.getElementById("theLayer");  
  hotDog=isIE ? event.srcElement : e.target;  
  while (hotDog.id!="titleBar"&&hotDog.tagName!=topDog){
    hotDog=isIE ? hotDog.parentElement : hotDog.parentNode;
  }  
  if (hotDog.id=="titleBar"){
    offsetx=isIE ? event.clientX : e.clientX;
    offsety=isIE ? event.clientY : e.clientY;
    nowX=parseInt(whichDog.style.left);
    nowY=parseInt(whichDog.style.top);
    ddEnabled=true;
    document.onmousemove=dd;
  }
}

function dd(e){
  if (!ddEnabled) return;
  whichDog.style.left=isIE ? nowX+event.clientX-offsetx : nowX+e.clientX-offsetx; 
  whichDog.style.top=isIE ? nowY+event.clientY-offsety : nowY+e.clientY-offsety;
  return false;  
}

function ddN4(whatDog){
  if (!isN4) return;
  N4=eval(whatDog);
  N4.captureEvents(Event.MOUSEDOWN|Event.MOUSEUP);
  N4.onmousedown=function(e){
    N4.captureEvents(Event.MOUSEMOVE);
    N4x=e.x;
    N4y=e.y;
  }
  N4.onmousemove=function(e){
    if (isHot){
      N4.moveBy(e.x-N4x,e.y-N4y);
      return false;
    }
  }
  N4.onmouseup=function(){
    N4.releaseEvents(Event.MOUSEMOVE);
  }
}

function hideMe(){
  if (isIE||isNN) whichDog.style.visibility="hidden";
  else if (isN4) document.theLayer.visibility="hide";
}

function showMe(){
  if (isIE||isNN) whichDog.style.visibility="visible";
  else if (isN4) document.theLayer.visibility="show";
}

document.onmousedown=ddInit;
document.onmouseup=Function("ddEnabled=false");

</script>

在网页<body>区添加以下代码


<div id="theLayer" style="position:absolute;width:250px;left:100;top:100;visibility:visible">
<table border="0" width="250" bgcolor="#424242" cellspacing="0" cellpadding="5">
<tr>
<td width="100%">
  <table border="0" width="100%" cellspacing="0" cellpadding="0" height="36">
  <tr>
  <td id="titleBar" style="cursor:move" width="100%">
  <ilayer width="100%" onSelectStart="return false">
  <layer width="100%" onMouseover="isHot=true;if (isN4) ddN4(theLayer)" onMouseout="isHot=false">
  <font face="Arial" color="#FFFFFF">Layer Title</font>
  </layer>
  </ilayer>
  </td>
  <td style="cursor:hand" valign="top">
  <a href="#" onClick="hideMe();return false"><font color=#ffffff size=2 face=arial  style="text-decoration:none">X</font></a>
  </td>
  </tr>
  <tr>
  <td width="100%" bgcolor="#FFFFFF" style="padding:4px" colspan="2">
This is where your content goes.<br>
It can be any html code or text.<br>
Remember to feed the reindeer.<br>
Avoid chewable giblet curtains.
<!-- END OF CONTENT AREA //-->
  </td>
  </tr>
  </table> 
</td>
</tr>
</table>
</div>




Using Show And Hide Controls

The layer can be shown or hidden via simple function calls.

To show the layer:

<a href="javascript:showMe();">show</a>

To hide the layer:

<a href="javascript:hideMe();">hide</a>

显示和隐藏层
<a href="javascript:showMe();">show</a> 显示层
<a href="javascript:hideMe();">hide</a> 隐藏层
