当鼠标点击增加时将层显示出来，再点击不显示层。下面的不知那里错了

<script language="javascript">
function check()
{
if(djadd.style.display=="none")
{
djadd.style.display="show";
}
if(djadd.style.display=="show")
{
djadd.style.display="none";
}
}
</script>
<p align="center"><onclick=check()>增加</p>

<div id="djadd" style="display:none;position:absolute; left:200px; top:450px; width:60px; height:40px; z-index:8;">
<table width="60" height="40" >
<tr><td >新增加1
</td></tr>
<tr><td >新增加2</td></tr>
</table>
</div>

这么写就对了。
<script language="javascript">
function check()
{
if(djadd.style.display=="none")
{
djadd.style.display="";
return false;
}
if(djadd.style.display=="")
{
djadd.style.display="none";
return false;
}
}
</script>

第一步:把如下代码加入<head>区域中
<script language="JavaScript1.2">
scores = new Array(20);var numTotal=0;NS4 = (document.layers) ? 1 : 0;IE4 = (document.all) ? 1 : 0;ver4 = (NS4 || IE4) ? 1 : 0;if (ver4) { with (document) { write("<STYLE TYPE='text/css'>"); if (NS4) { write(".parent {position:absolute; visibility:visible}"); write(".child {position:absolute; visibility:visible}"); write(".regular {position:absolute; visibility:visible}") } else { write(".child {display:none}") } write("</STYLE>"); }}function getIndex(el) { ind = null; for (i=0; i<document.layers.length; i++) { whichEl = document.layers[i]; if (whichEl.id == el) { ind = i; break; } } return ind;}function arrange() { nextY = document.layers[firstInd].pageY +document.layers[firstInd].document.height; for (i=firstInd+1; i<document.layers.length; i++) { whichEl = document.layers[i]; if (whichEl.visibility != "hide") { whichEl.pageY = nextY; nextY += whichEl.document.height; } }}function initIt(){ if (!ver4) return; if (NS4) { for (i=0; i<document.layers.length; i++) { whichEl = document.layers[i]; if (whichEl.id.indexOf("Child") != -1) whichEl.visibility = "hide"; } arrange(); } else { divColl = document.all.tags("DIV"); for (i=0; i<divColl.length; i++) { whichEl = divColl(i); if (whichEl.className == "child") whichEl.style.display = "none"; } }}function expandIt(el) { if (!ver4) return; if (IE4) { whichEl1 = eval(el + "Child"); for(i=1;i<=numTotal;i++){ whichEl = eval(scores[i] + "Child"); if(whichEl!=whichEl1) { whichEl.style.display = "none"; } } whichEl1 = eval(el + "Child"); if (whichEl1.style.display == "none") { whichEl1.style.display = "block"; } else { whichEl1.style.display = "none"; } } else { whichEl = eval("document." + el + "Child"); for(i=1;i<=numTotal;i++){ whichEl = eval("document." + scores[i] + "Child"); if(whichEl!=whichEl1) { whichEl.visibility = "hide"; } } if (whichEl.visibility == "hide") { whichEl.visibility = "show"; } else { whichEl.visibility = "hide"; } arrange(); }}onload = initIt;
</script>
