<form Name="InputForm">
<div align="center"><center><p><script language="JavaScript">

function StartSearch()
{
document.forms[FirstForm+document.InputForm.SearchSelect.
selectedIndex].elements[0].value=document.InputForm.SearchWords.value;
document.forms[FirstForm+document.InputForm.SearchSelect.
selectedIndex].submit();
}
</script><span style="font-size: 9pt">查找内容:</span><input name="SearchWords" type="text" size="21"
