#search{

input type="button" name="" id="bbtn" value="搜索" /

div id="div"

p馋，在英文里找不到一个十分适当的字。罗马暴君尼禄，以至于英国的亨利八世，在大宴群臣的时候，常见其撕下一根根又粗又壮的鸡腿，举起来大嚼，旁若无人，好一副饕餮相！但那不是馋。埃及废王法鲁克，据说每天早餐一口气吃二十个荷包蛋，也不是馋，只是放肆，只是没有吃相。对有某一种食物有所偏好，于是大量的吃，这是贪多无厌。馋，则着重在食物的质，最需要满足的是品味。上天生人，在他嘴里安放一条舌，舌上还有无数的味蕾，教人焉得不馋？馋，基于生理的要求；也可以发展成为近于艺术的趣味。 

也许我们中国人特别馋一些。馋字从食，有声。毚音谗，本义是狡兔，善于奔走，人为了口腹之欲，不惜多方奔走以膏馋吻，所谓“为了一张嘴，跑断两条腿”。/p

/div

script type="text/javascript"

var bbtn=document.getElementById('bbtn');

var search=document.getElementById('search');

var text=document.getElementsByTagName('p')[0];

var text1=text.innerHTML;

var arr=[];

var str=text1;

bbtn.onclick=function(){

str=text1

arr=search.value;

str=str.split(arr).join('span'+arr+'/span');

text.innerHTML=str;

}

/script

/body

/html

二：对li表单的搜索：

}

ul{

li{

}

/style

/head

body

div id="content"

ul

input type="" name="" id="" value="" placeholder="请输入城市的名称或拼音"/

li pname="北京" cname="bj"北京/li

li pname="南京" cname="nj"南京/li

/ul

/div

script type="text/javascript"

var li=document.getElementsByTagName('li');

var text=document.getElementsByTagName('input')[0];

function search(){

var arr=text.value;

for(var i=0;ili.length;i++)

{

li[i].style.display="none";

if(li[i].getAttribute('pname').indexOf(arr)!=-1||li[i].getAttribute('cname').indexOf(arr)!=-1)

{

li[i].style.display="block";

}

}

}

text.oninput=function(){

search();

}

/script

/body

/html

谁知道国家选省份的javascript脚本，给个例子地址也可以。谢谢大家了！

这个是我国的各省的城市选择网页,你可以按自己的要求进行一些改动.

如你要提取市的数据，你需要在接受请求页面写如下代码：

shi=trim(request.form("city"))

就可以得到市的值了。

还有这是用Form传递参数，而不是用QueryString传递。

jsp中利用javascript实现三级联动

js代码

//级联菜单

var province = ['江西省','江苏省','浙江省','甘肃省','江西省','江苏省','浙江省','甘肃省'];

var city = Array(

new Array ('南昌市','赣州市','抚州市','上饶市'),

new Array('杭州市','温州市','宁波市'),

new Array('南京市','苏州市','昆山市','太仓市'),

new Array('兰州市','敦煌市','兰楼市'),

new Array ('南昌市','赣州市','抚州市','上饶市'),

new Array('杭州市','温州市','宁波市'),

new Array('南京市','苏州市','昆山市','太仓市'),

new Array('兰州市','敦煌市','兰楼市')

)

//遍历省份

for(var i=0;iprovince.length;i++){

var opt = document.createElement('option'); //创建一个结点

opt.value = province[i]; //在value显示

opt.innerHTML = opt.value; //页面显示

document.getElementById('big').appendChild(opt);

}

//省份值改变的时候调用函数

function show_small(){

//alert( document.getElementById('big').selectedIndex);//拿到下标

document.getElementById('small').innerHTML="";//清空 appendChild会追加

var index = document.getElementById('big').selectedIndex;

for(var i=0;icity[index-1].length;i++){ //注意下标

var opt = document.createElement('option');

opt.value = city[index-1][i];

opt.innerHTML = opt.value;

document.getElementById('small').appendChild(opt);

}

}

html代码

!-- 级联菜单--

select id="big" onchange="show_small()"

option value=""--select--/option

/select

select id="small"

option value=""--select--/option

/select

手上刚好有个二级联动的，三级联动的你可以自己看着加进去，希望对你有帮助
