脚本说明:
第一步：把如下代码加入<body>区域中
<script language="javascript">
<!-- hide script from old browsers
keyword = new object();
descrip = new object();
address = new object();

// keyword[0] = n (where n is the number of keywords which can be searched
keyword[0] = 5 //对应查询组的数量;

keyword[1] = "javascript"
descrip[1] = "最全的javascript资源站-javascript2000.com"
address[1] = "http://www.javascript2000.com"

keyword[2] = "javascript"
descrip[2] = "很好的javascript站点"
address[2] = "http://www.cnlot.com/"

keyword[3] = "javascript"
descrip[3] = "java神捕"
address[3] = "http://pcafei.3322.net/"

keyword[4] = "javascript"
descrip[4] = "精彩天地"
address[4] = "http://demoy.3322.net/"

keyword[5] = "javascript"
descrip[5] = "国外最大的javascript资源站"
address[5] = "http://www.javascript.com/"
function checkdatabase() {

var found = false
var item = document.forms[0].searchfor.value.tolowercase();

stats='toolbar=no,location=no,directories=no,status=no,menubar=no,'
stats += 'scrollbars=yes,resizable=yes'
msgbox = window.open ("","msgwindow",stats)
msgbox.document.write("<head><title>查询结果</title></head>");
msgbox.document.write ("<body bgcolor=#ffffff text=#000000 link=#000080 vlink=#800040
alink=#ff0000><center>查询结果</center>")
msgbox.document.write ("for the keyword: "+item+"<hr>");
for (var i=1; i <= keyword[0]; i++) {
if(item == keyword[i]) {
found = true;
msgbox.document.write (descrip[i]+"<br><a href="+address[i]+">click here to view</a><br>")

}
}
if(!found)
msgbox.document.write ("没有发现与该关键词有关的条目。")
msgbox.document.write ("<h6>enjoy it!<br><a href=http://java2000.126.com>http://java2000.126.com</a></h6>")
msgbox.document.write ("<form class='pt9'><center>")
msgbox.document.write ("<input type='button' value='关闭查询窗口' onclick = 'self.close()'>")
msgbox.document.write ("</center></form>") }
// -->
</script>

如下代码生成查询表单界面：

<form name="form1">
<u>请输入查询关键词:</u><br>
<input type="text" name="searchfor" value="" size=20>
<input type="button" value="查询" onclick="checkdatabase()" name="button">
<br>
<!-- end of file -->
<font color="#ff0000">输入小写字符</font>
<p>
</form>
