tab菜单的实现

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
    <style>
        .hide{
            display: none;
        }
        .active{
            background-color: brown;
        }
        .menu{
            height: 38px;
            background-color: #eeeeee;
            line-height: 38px;

        }
        .menu .menu-item{
            float: left;
            border-right: 1px solid red;
            padding: 0 5px;
            cursor: pointer;
        }
        .content{
            min-height: 100px;
            border: 1px solid #eeeeee;
        }
    </style>
</head>
<body>
    <div style=" 700px;margin: 0 auto">
        <div class="menu">
            <div class="menu-item active" a="1">菜单一</div>
            <div class="menu-item" a="2">菜单二</div>
            <div class="menu-item" a="3">菜单三</div>
        </div>
        <div class="content">
            <div b="1">内容一</div>
            <div class="hide" b="2">内容二</div>
            <div class="hide" b="3">内容三</div>

        </div>

    </div>
    <script src="jquery.js"></script>
    <script>
        $('.menu-item').click(function () {

           $(this).addClass('active').siblings().removeClass('active')
            var targt = $(this).attr('a')
            $('.content').children("[b='"+ targt+"']").removeClass('hide').siblings().addClass('hide')
        });

    </script>
</body>
</html>

第二种方式（通过索引实现）：

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
    <style>
        .hide{
            display: none;
        }
        .active{
            background-color: brown;
        }
        .menu{
            height: 38px;
            background-color: #eeeeee;
            line-height: 38px;

        }
        .menu .menu-item{
            float: left;
            border-right: 1px solid red;
            padding: 0 5px;
            cursor: pointer;
        }
        .content{
            min-height: 100px;
            border: 1px solid #eeeeee;
        }
    </style>
</head>
<body>
    <div style=" 700px;margin: 0 auto">
        <div class="menu">
            <div class="menu-item active" a="1">菜单一</div>
            <div class="menu-item" a="2">菜单二</div>
            <div class="menu-item" a="3">菜单三</div>
        </div>
        <div class="content">
            <div b="1">内容一</div>
            <div class="hide" b="2">内容二</div>
            <div class="hide" b="3">内容三</div>

        </div>

    </div>
    <script src="jquery.js"></script>
    <script>
        $('.menu-item').click(function () {

           $(this).addClass('active').siblings().removeClass('active')
            $('.content').children().eq($(this).index()).removeClass('hide').siblings().addClass('hide')
        });

    </script>
</body>
</html>
