第一步:把如下代码加入%26lt;body%26gt;区域中
%26lt;script language=%26quot;JavaScript%26quot;%26gt;
%26lt;!--
// 下面是负责搜索的页面的全路径或相对路径
var search_htm_url = %26quot;searchsource.htm%26quot;;
function searchPage() {
if ((document.searchpage.keyword.value.length == 0)
|| (document.searchpage.keyword.value == %26quot; %26quot;)) {
alert(%26quot;请填入关键字!%26quot;);
} else {
sel = document.searchpage.and_or.selectedIndex;
location.href = search_htm_url + %26quot;?%26quot;
+ escape(document.searchpage.keyword.value)
+ (sel==0?%26quot;%26amp;and%26quot;:(sel==2?%26quot;%26amp;exact%26quot;:%26quot;%26amp;or%26quot;));
}
return false;
}
document.write('%26lt;form name=%26quot;searchpage%26quot; onSubmit=%26quot;return searchPage()%26quot;%26gt;'
+'请填入关键字: %26lt;input type=%26quot;text%26quot; size=22 name=%26quot;keyword%26quot;%26gt; '
+'%26lt;input type=%26quot;button%26quot; value=%26quot;Search%26quot; onClick=%26quot;searchPage()%26quot;%26gt;%26lt;br%26gt;'
+'%26lt;select name=%26quot;and_or%26quot; size=1%26gt;%26lt;option%26gt;关键字与搜索%26lt;option%26gt;关键字或搜索 '
+'%26lt;option%26gt;关键字异或搜索%26lt;/select%26gt;%26lt;/form%26gt;');
// --%26gt;
%26lt;/script%26gt;
第二步:新建searchsource.htm 其内容为
%26lt;!-- 代码开始--%26gt;
%26lt;form NAME=%26quot;database%26quot;%26gt;
%26lt;input type=%26quot;hidden%26quot; name=%26quot;list%26quot;
