<script src="jquery-1.6.2.min.js" type="text/javascript"></script>
<script type="text/javascript">
var oldColor;
$(function () {
//注册ID为btnTest的按钮的click事件
$("#btnTest").click(function () {
var $divs = $("div");
$divs.html("我是修改后的Div文本");
});
//注册ID为btnTest的按钮的mouseover事件,鼠标经过时添加背景色
$("#btnTest").mouseover(function () {
oldColor = $("#btnTest").css("background-color");
$("#btnTest").css("background-color", "green");
});
//注册ID为btnTest的按钮的mouseout事件,鼠标离开时还原背景色
$("#btnTest").mouseout(function () {
$("#btnTest").css("background-color", oldColor);
});
});
</script>

<body>
<div id="main">
<div id="div1" class="myDiv">我是div1
<div id="divSun">我是孙子div
<div id="divSunSun">我是孙子的孙子div</div>
</div>
<div id="divSun1">我是孙子div</div>
</div>
<div id="div2" class="myDiv">我是div2</div>
</div>
<div id="main1"></div>
<div id="main2"></div>
<input id="btnTest" type="button" value="测试按钮" />
