不错的页面搜索脚本
要完成此效果需要两个步骤
第一步：把如下代码加入到<body>区域中
<div align="center">
<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 = "test.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(试试填入java): <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>
</div>
第二步：同一目录新建“test.htm”内容如下
<form NAME="database">
<input type="hidden" name="list"
value="http://typhoon.500.to~Typhoon Start|javascript乐园 ^JavaScript Fairyland
">
</form>
<!--以上可以自行调整-->
<script language="JavaScript">
<!--
function Page(url,title,keywords,description) {
while ((url.length > 0) && (url.charAt(0) == " ")) {
url = url.substring(1,url.length);
}
this.url = url;
while ((title.length > 0) && (title.charAt(0) == " ")) {
title = title.substring(1,title.length);
}
this.title = title;
this.keywords = keywords;
this.description = description;
return this;
}
function Database() {
var pos = 0;
while ((pos1 = amorphous.indexOf("~",pos)) != -1) {
pos2 = amorphous.indexOf("|",pos1+1);
pos3 = amorphous.indexOf("^",pos2+1);
pos4 = amorphous.indexOf("*",pos3+1);
if ((pos2 != -1)
&& (pos2 < pos3) && (pos3 < pos4)
&& (pos4 <= amorphous.indexOf("*",pos))) {
this[database_length++] = new Page(amorphous.substring(pos,pos1),
amorphous.substring(pos1+1,pos2),
amorphous.substring(pos2+1,pos3),
amorphous.substring(pos3+1,pos4));
pos = pos4+1;
} else { // error reading amorphous database
if (pos+30 <= amorphous.length)
alert('Error reading in amorphous database around "'
+ amorphous.substring(pos,pos+30) + '"');
pos = amorphous.indexOf("*",pos) + 1;
}
}
return this;
}
function search(str) {
menu_length = 0;
temp = new Object();
temp_length = 0;
words_length = 0;
words = new Object();
pos = 0;
while ((pos = str.indexOf(" ")) != -1
&& and_search != "exact") {
words[words_length] = str.substring(0,pos);
if (words[words_length].length > 0)
words_length++;
if (str.length == 1)
str="";
else
str = str.substring(pos+1,str.length);
}
if (str.length > 0)
words[words_length++] = str;
for (q=0;q<words_length;q++) {
temp_length = 0;
str = words[q].toLowerCase();
len = (and_search=="and"&&q>0?menu_length:database_length);
for (n=0; n<len; n++) {
if (and_search=="and"&&q>0) {
