複製代碼 代碼如下:
<style type="text/css">
body {
font-size:12px;text-align:center;
}
#tbStu {
width:260px;border:1px solid #666;background-color:#eee;
}
#tbStu tr {
line-height:23px;
}
#tbStu tr th {
background-color:#ccc;color:#fff;
}
#tbStu .trOdd {
background-color:#fff;
}
</style>
<script src="jQuery/jquery-1.9.1.js"></script>
<script type="text/javascript">
//普通JS寫法
//window.onload = function () {
// var oTb = document.getElementById('tbStu');
// for (var i = 0; i < oTb.rows.length-1; i++) {
// if (i % 2)
// {
// oTb.rows[i].className = "trOdd";
// }
// }
//}
//jQuery選取器寫法（選擇table的行，隔一行，選擇一行）
$(function () {
$('#tbStu tr:nth-child(even)').addClass("trOdd");
//jQuery給一個DIV複製內容時，不需要檢測該DIV是否存在
// $('#divMain').html('這是一個檢測頁面');
})
</script>
</head>
