xsl中的div显示问题

[phygold]

<div id="prt" style="display:block">
<p align="center">
<input type="submit" value="隐藏" onClick="pt();" width="50"/>
<input type="hidden" width="10"/>
<input type="submit" value="关闭" onClick="window.close();" width="50"/>
</p>
</div>

<script language="javascript">

function pt()
{
prt.style.display="none";
prt.style.display="block";

}

</script>

div在xsl下无法隐藏，该如何解决？

<script language="javascript">

function pt()
{
prt.style.display="none";
//prt.style.display="block";//这块不应该加了吧？？？

}

</script>

<font id="font_div_1" onmouseover="this.style.color='red';this.style.cursor='hand';" onmouseout="this.style.color='black';" onclick="font_click(this);">1重要提示</p></font>
<div id="div_1" style="visibility:'visible';">asdfasdfasdfasdf</div>
<script language="javascript">
function font_click(obj){
var divobj=eval(obj.id.replace("font_",""));
divobj.style.display=="none"?divobj.style.display="block":divobj.style.display="none";
}
</script>
