一个树状展开的javascript代码的问题

如 http://h.tangshan.cc/l_mail.asp 这里的网页，现在打网页是关闭的，能不能改成一打开，网页就是打开的？本人太菜，不会修改。请高手帮忙

部分代码如下：
<TABLE cellSpacing=0 cellPadding=0 width=210 border=0>
<TBODY>
<TR>
<TD height=21 style="font-size: 9pt">
<SCRIPT language=javascript>
function opencat(cat,img){
if(cat.style.display=="none"){
cat.style.display="";
img.src="img/class2.gif";
} else {
cat.style.display="none";
img.src="img/class1.gif";
}
}
</Script>
<TABLE cellSpacing=0 cellPadding=0 width="99%" border=0>

<TR>
<TD language=javascript onmouseup="opencat(cat101000, img101000);" id=item$pval[catID]) style="CURSOR: hand; font-size:12px" width=90 height=20 align=center>
<IMG id=img101000 src="henry/class1.gif" width=20 height=20></TD>
<TD language=javascript onmouseup="opencat(cat101000, img101000);" id=item$pval[catID]) style="CURSOR: hand; font-size:12px" width="662" style="font-size: 12px"><b>

</TR>
<TR>
<TD id=cat101000 style='DISPLAY: none; font-size:12px' colspan="2">
