本文目录:
一、提问：怎样实现点击一个按钮弹出下拉列表
用css把按钮弄成下列表的样式，用一个事件，按下时，调用一个显示div的样式，div里面，是一个真正的下拉框。。。div弹出时设置位置时，盖住按钮即可。
二、html 链接点击一下显示下拉内容（再点击一下自动收回），上一次点击内容自动收回，代码怎么写？谢谢！
在isHidden函数中添加如下代码即可：
function isHidden(oDiv){
var vDiv = document.getElementById(oDiv);
vDiv.style.display = (vDiv.style.display == 'none')?'block':'none';
// add code
var allDiv = document.getElementsByTagName('div');
for (var i=0; i<allDiv.length; i++) {
if (vDiv != allDiv[i]) {
allDiv[i].style.display = 'none';
}
}
}
三、网站搜索框下拉菜单代码
我不知道具体的代码。但我觉得那个不是程序里的代码做的。应该是绑定数据库的时候通过Sql语句的模糊查询做到的。。。。
例如:
"select * from table where name like ' % " + textbox1.Text + " % ' "
上面这段语句的用处就是在数据库里查找name字段中含有textbox1.Text内容的数据。
经测试（可以查到中文，英文，数字）不论是首字符或在字符串中间结尾都可以查到。
但做不到像BAIDU那样输入pinyin字母就搜到对应的中文查询结果。
四、网页设计关于下拉列表的代码
看看这个不错：
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312" />
<title>Untitled Document</title>
<script language="JavaScript" type="text/javascript">
