懸浮窗，點選收縮/張開
效果圖
說明：點選”+“按鈕，懸浮窗收縮/展開
思路
1、在html中定義一個div塊，定一個id；一個按鈕，點選時用。
2、寫一個js,包含收縮以及展開的函式；為按鈕新增點選事件。
3、想要讓懸浮窗好看點，可設定對應的引數。
步驟
html
<div id="area">
<div id="small_menu">
<ul>
<li><a href="#">item one</a js
var menubox = document.getElementById("area"); //area為選單欄的id
var cli_on = document.getElementById("on" 完整程式碼
含css,可直接用
