javascript - jQuery 图像 slider 不适用于 jQuery 循环 (ASP.NET)

Question

我正致力于在我的 ASP.NET 网络应用程序上使用 jQuery 实现强制性图像 slider 。我可以看到第一张图片，但是当我按下一张或一张按钮时，它不起作用。

我也安装了 jQuery.cycle 插件，但不知道哪里出了问题。我需要另一个插件和 jQuery 循环吗？

HTML

<div id="slider-nav">

        <div id="next">&rang;</div>
        <div id="prev">&lang;</div>

        <div id="slider">
            <img src="~/img/img1.jpg" alt="image">
            <img src="~/img/img2.jpg" alt="image">
            <img src="~/img/img3.jpg" alt="image">
        </div>
    </div>

CSS

<style type="text/css">

    #slider-nav{
        width: 700px;
        height: 280px;
        position: relative;
        margin: 50px auto;
    }

    #slider{
        width: 700px;
        height: 280px;
        position: absolute;
        overflow: hidden;
    }

    #next {
        text-align: center;
        line-height: 50px;
        color: white;
        width: 50px;
        height: 50px;
        background-color: black;
        position: absolute;
        top: 120px;
        right: 0;
        z-index: 99;
        cursor: pointer;
        opacity: 0;
    }

    #prev {
        text-align: center;
        line-height: 50px;
        color: white;
        width: 50px;
        height: 50px;
        background-color: black;
        position: absolute;
        top: 120px;
        left: 0;
        z-index: 99;
        cursor: pointer;
        opacity: 0;
    }

    #slider-nav:hover #next {
        opacity: 1;
        transition: all .5s ease-out;
        -webkit-transition: all .5s ease-out;
    }

    #slider-nav:hover #prev {
        opacity: 1;
        transition: all .5s ease-out;
        -webkit-transition: all .5s ease-out;
    }
  </style>

Javascript

<script type="text/javascript" src="~/Scripts/jquery-3.1.1.js"></script>
<script type="text/javascript" src="~/Scripts/jquery.cycle.all.js"></script>
<script type="text/javascript" src="~/Scripts/jquery.cycle.all.min.js"></script>

<script type="text/javascript">

    $('#slider').cycle({
        fx: 'scrollHorz',
        next: '#next',
        prev: '#prev',
        timeout: 3000,
        pause: 1
    });
</script>

删除重复项 <script type="text/javascript" src="~/Scripts/jquery.cycle.all.min.js"></script>

您已经调用了它(.min 表示脚本的缩小版本。)

并将你的调用包装在一个就绪 block 中

<script type="text/javascript">
$( document ).ready(function() {
    $('#slider').cycle({
        fx: 'scrollHorz',
        next: '#next',
        prev: '#prev',
        timeout: 3000,
        pause: 1
    });
});
</script>

更新: 我使用您的确切代码创建了一个片段。它工作得很好。 这表明您的其他脚本正在干扰。

    $('#slider').cycle({
        fx: 'scrollHorz',
        next: '#next',
        prev: '#prev',
        timeout: 3000,
        pause: 1
    });

    #slider-nav{
        width: 700px;
        height: 280px;
        position: relative;
        margin: 50px auto;
    }

    #slider{
        width: 700px;
        height: 280px;
        position: absolute;
        overflow: hidden;
    }

    #next {
        text-align: center;
        line-height: 50px;
        color: white;
        width: 50px;
        height: 50px;
        background-color: black;
        position: absolute;
        top: 120px;
        right: 0;
        z-index: 99;
        cursor: pointer;
        opacity: 0;
    }

    #prev {
        text-align: center;
        line-height: 50px;
        color: white;
        width: 50px;
        height: 50px;
        background-color: black;
        position: absolute;
        top: 120px;
        left: 0;
        z-index: 99;
        cursor: pointer;
        opacity: 0;
    }

    #slider-nav:hover #next {
        opacity: 1;
        transition: all .5s ease-out;
        -webkit-transition: all .5s ease-out;
    }

    #slider-nav:hover #prev {
        opacity: 1;
        transition: all .5s ease-out;
        -webkit-transition: all .5s ease-out;
    }
