无法使用unlider jQuery插件定位我的箭头

时间：2014-03-25 03:01:01

标签： javascript jquery slider slideshow jquery-ui-slider

我正在按照unslider的文档开发带有点和箭头的幻灯片。

我已经按照自己的意愿工作，但箭头上有一些问题。

我没有将左箭头对齐我的滑块左侧，右箭头对齐我的幻灯片右侧。我已经做了很多测试，但没有任何工作。

你知道我们如何用unlider插件做到这一点吗？

我的HTML 

<section id="banner-container">

    <div class="banner">

        <ul>
           <li style="background-color:red;  height:500px;">This is another slide.</li>
            <li style="background-color:green;  height:500px;">This is another slide.</li>
           <li style="background-color:blue;  height:500px;">This is another slide.</li>   
        </ul>
        <a href="#" class="unslider-arrow prev"></a>
        <a href="#" class="unslider-arrow next"></a>
    </div>

</section>

我的CSS： 

  #banner-container
    {
        width:100%;
        float:left;
    }


    .banner
    {   position: relative; 
        overflow: auto;
        width: 100%;
    }

    .banner li
    {
        list-style:none;
        background-repeat:no-repeat;
        background-size:cover;
    }

    .banner ul li
    { 
        float: left;
    }

    .banner ul li img
    {   width:100%;
        height:220px;
    }
    .banner .dots 
    {   margin-left:50%;
        bottom: 10px;
        left: 0;
        position: absolute;
        right: 0;
        display:none;
    }

    .banner:hover .dots 
    {
        display:block;
    }

    .banner .dots li
    { 
        border: 2px solid #fff;
        border-radius: 6px;
        cursor: pointer; 
        display: inline-block;
        height: 10px;
        margin: 0 4px;
        opacity: .4; 
        text-indent: -999em; 
        -webkit-transition: background .5s, opacity .5s;
        -moz-transition: background .5s, opacity .5s;
        transition: background .5s, opacity .5s; width: 10px;
    }

    .banner .dots li.active 
    { 
        background: #fff;
        opacity: 1;
    }

.arrows .prev {
    position: relative;
    top: -136px;
}
.arrows .next {
    position: absolute;
    right: 0;
    top: 109px;
}

我的jQuery： 

$(function() {
    $('.banner').unslider({

        speed: 2000,
        delay: 2000,
        fluid: true,
        dots: true,
        arrows: true,
        pause: true


    });
});

答案 0 :(得分：1)

您遇到的问题是您的CSS代码没有解决＆lt; a＆gt; s因为它们具有不同的className。两个选项：

＃1 - 切换CSS文件中的classNames：

.unslider-arrow.prev {...}
.unslider-arrow.next {...}

＃2 - 切换＆lt;中的类。 a＆gt; s到你在CSS文件中使用的那些：

<a href="#" class="arrow prev"></a>
<a href="#" class="arrow next"></a>

但是，使用第二个选项时，您必须将CSS中的关系更改为：

.arrow.prev {}
.arrow.next {}
