搜索按钮(客户端表单)

这个比较长，只要将下列代码加入<body></body>之间就行：
<form Name="InputForm">
<div align="center"><center><p><script language="JavaScript">
var FirstForm;
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"
style=" margin-left: 1px"><br>
<span style="font-size: 9pt">搜索引擎:</span><select Name="SearchSelect" size="1" style="background-color:
