第一步，实现百度输入法的页面布局
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<title>百度输入法</title>
<style>
body,ul,li,button{margin:0;padding:0;}
body{font:12px/1.5 Tahoma;}
ul{list-style-type:none;}
button{cursor:pointer;}
#outer{width:70px;margin:10px auto;}
#ime{margin-top:5px;background:#fff;border:1px solid #9a99ff;display:none;}
#ime li{width:100%;line-height:24px;display:inline-block;vertical-align:top;}
#close{border-top:1px solid #9a99ff;}
#ime li a{color:#00c;padding:0 5px;display:block;text-decoration:none;}
#ime li a:hover{background:#d9e1f6;}
</style>
</head>
<body>
<div id="outer">
<button>输入法</button>
<ul id="ime">
<li><a href="javascript:;">手写</a></li>
<li><a href="javascript:;">拼音</a></li>
<li id="class"><a href="javascript:;">关闭</a></li>
</ul>
</div>
</body>
</html>
第二步，用js实现功能
<script>
window.onload = function ()
{
var oBtn = document.getElementsByTagName("button")[0];
var oIme = document.getElementById("ime");
var oClose = document.getElementById("close");
var style = oIme.style;
oBtn.onclick = function()
{
style.display = style.display == "block" ? "none" : "block"
};
oClose.onclick = function()
{
style.display = "none"
}
}
</script>
