jQuery实现商品详情详细参数页面切换

利用index实现：

<!DOCTYPE html>

<html lang="en">

<head>

    <meta charset="UTF-8">

    <title>Title</title>

<style>

    .hide{display:none;}

    .item{

        height: 38px;

        width: 800px;

        border: 1px solid #dddddd;

        margin: 0 auto;

    }

    .item .item-content{

        float: left;

        line-height: 38px;

        padding: 0 15px;

        border-right: 1px solid #dddddd;

        cursor: pointer;

    }

    .item .active{

        background-color: #eeeeee;

        color: red;

        font-weight: bold;

    }

    .content{

        height: 500px;

        width: 800px;

        border: 1px solid #dddddd;

        margin: 0 auto;

    }

    .content .content-content{}

</style>

</head>

<body>

<div class="item">

    <div class="item-content active">商品介绍</div>

    <div class="item-content">详细参数</div>

    <div class="item-content">客户评价</div>

</div>

<div class="content">

    <div class="content-content">内容1</div>

    <div class="content-content hide">内容2</div>

    <div class="content-content hide">内容3</div>

</div>

<script src="jquery-3.3.1.js"></script>

<script>

    // 利用索引实现，代码简洁，但依赖全局唯一的样式item-content content-content，所以注意这二种新式只在这儿使用，且item-content和content-content的内容顺序要对应。

    $('.item-content').click(function () {

        $(this).addClass('active').siblings().removeClass('active');

        $('.content-content').eq($(this).index()).removeClass('hide').siblings().addClass('hide');

    });

</script>

</body>

</html>

利用自定义属性实现：

<!DOCTYPE html>

<html lang="en">

<head>

    <meta charset="UTF-8">

    <title>Title</title>

<style>

    .hide{display:none;}

    .item{

        height: 38px;

        width: 800px;

        border: 1px solid #dddddd;

        margin: 0 auto;

    }

    .item .item-content{

        float: left;

        line-height: 38px;

        padding: 0 15px;

        border-right: 1px solid #dddddd;

        cursor: pointer;

    }

    .item .active{

        background-color: #eeeeee;

        color: red;

        font-weight: bold;

    }

    .content{

        height: 500px;

        width: 800px;

        border: 1px solid #dddddd;

        margin: 0 auto;

    }

    .content .content-content{}

</style>

</head>

<body>

<div class="item">

    <div itemId="1" class="item-content active">商品介绍</div>

    <div itemId="2" class="item-content">详细参数</div>

    <div itemId="3" class="item-content">客户评价</div>

</div>

<div class="content">

    <div contentId="1" class="content-content">内容1</div>

    <div contentId="3" class="content-content hide">内容3</div>

    <div contentId="2" class="content-content hide">内容2</div>

</div>

<script src="jquery-3.3.1.js"></script>

<script>

    // 利用自定义属性itemId contentId相对应，这样不依赖于顺序，children会用到字符串拼接

    $('.item').children().click(function () {

        $(this).addClass('active').siblings().removeClass('active');

        var index = $(this).attr('itemId');

        $('.content').children("[contentId="+index+"]").removeClass('hide').siblings().addClass('hide');

    });

</script>

</body>

</html>
