表格 隔行换色

1.原生JS实现

<script type="text/javascript">
        var oTable = document.getElementById("table");
        var oTr = oTable.getElementsByTagName("tr");
        for (var i=0; i<oTr.length;i++)
        {
            if (i%2)
                oTr[i].style.background = "yellow";
        }
</script>

2.Jquery实现

<script type="text/javascript">
    $('#table tr:even').css("background", "yellow");
</script>

 

<script type="text/javascript">
        $('#table tr').filter(":even").css("background", "#abcdef").end().filter(":odd").css("background", "yellow");
</script>
