JavaScript实例 站内搜索例子 （一）
时间：2007-02-17 来源：PHP爱好者
脚本说明:
第一步：把如下代码加入<body>区域中
<script language="JavaScript">
<!--
// 下面是负责搜索的页面的全路径或相对路径
var search_htm_url = "searchsource.htm";
function searchPage() {
if ((document.searchpage.keyword.value.length == 0)
|| (document.searchpage.keyword.value == " ")) {
alert("请填入关键字!");
} else {
sel = document.searchpage.and_or.selectedIndex;
location.href = search_htm_url + "?"
+ escape(document.searchpage.keyword.value)
+ (sel==0?"&and":(sel==2?"&exact":"&or"));
}
return false;
}
document.write('<form name="searchpage" onSubmit="return searchPage()">'
+'请填入关键字: <input type="text" size=22 name="keyword"> '
+'<input type="button" value="Search" onClick="searchPage()"><br>'
+'<select name="and_or" size=1><option>关键字与搜索<option>关键字或搜索 '
+'<option>关键字异或搜索</select></form>');
// -->
</script>
第二步：新建searchsource.htm 其内容为
<!-- 代码开始-->
<form NAME="database">
<input type="hidden" name="list"
