如何在猫头鹰轮播中创建导航箭头

Question

我正在努力实现Owl Carousel的基本功能。在我的轮播中，用户只能通过选择并按住一个图像并拖动来浏览幻灯片。它没有给用户提示他们可以实际浏览和拖动更多图像。我想要的只是放一个上一个/下一个箭头，这样人们就可以点击箭头并在旋转木马中查看更多图像。但我正在努力做到这一点可能是因为旋转木马以复杂的方式实施。

我的网站是在Wordpress上，但Owl carousel插件尚未使用。它是手动实现的。轮播中的图像是从数据库中提取的。

这是旋转木马获取图像的方式。文件名shortcode.php

function carousel_register( $atts, $content = null ) {

extract(shortcode_atts(array(
  'group_id' => ''
), $atts));

if(isset($group_id)){
    $to_add = '?g='.$group_id[0];
}else{
    $to_add = '';
}



$output = '<section id="carousel" class=""><div class="container" align="center"><h2>Simply Choose Your Agent</h2><div id="agents-carousel" class="agents-carousel">';

foreach ($data_json['data'] as $k => $v) {

        if ($v['onlinestatus'] == 1) {
            $online = "Online";
        }
        if ($v['onlinestatus'] == 0) {
            $online = "Offline";
        }

        $name = preg_replace("/[^A-Za-z0-9]/", "", $v['display_name']);

        $output .= '<div class="item"><a href="'.get_site_url().'/'.strtolower($v['display_name']).'"><div class="image-carousel"><img src="'.get_site_url().'/profile-image/medium/'.$v['id_user'].'/'.$name.'.png"></div></a></div>';
}
$output .='</div><div class="cta"><a href="'.get_site_url().'/our-readers/">discover all readers</a></div></div></section>';
return $output;

   }


add_shortcode( 'carousel', 'carousel_register' );

有近25张图片，其中只有5张正在展示。他们可以通过抓住它们来拖延。我只想添加导航箭头和点。

.owl-carousel .owl-wrapper:after {
    content: ".";
    display: block;
    clear: both;
    visibility: hidden;
    line-height: 0;
    height: 0; }
 .owl-carousel{
    display: none;
    position: relative;
    width: 100%;
   -ms-touch-action: pan-y;}
.owl-carousel .owl-wrapper{
    display: none;
    position: relative;
   -webkit-transform: translate3d(0px, 0px, 0px);}
.owl-carousel .owl-wrapper-outer{
    overflow: hidden;
    position: relative;
    width: 100%;}
.owl-carousel .owl-wrapper-outer.autoHeight{
    -webkit-transition: height 500ms ease-in-out;
    -moz-transition: height 500ms ease-in-out;
    -ms-transition: height 500ms ease-in-out;
    -o-transition: height 500ms ease-in-out;
    transition: height 500ms ease-in-out;}
   .owl-carousel .owl-item{
    float: left;}
.owl-controls .owl-page, .owl-controls .owl-buttons div{
    cursor: pointer;}
.owl-controls {
   -webkit-user-select: none;
   -khtml-user-select: none;
   -moz-user-select: none;
   -ms-user-select: none;
   user-select: none;
   -webkit-tap-highlight-color: rgba(0, 0, 0, 0);}
.grabbing {
    cursor:url(grabbing.png) 8 8, move;}
.owl-carousel .owl-wrapper, .owl-carousel .owl-item{
    -webkit-backface-visibility: hidden;
    -moz-backface-visibility: hidden;
    -ms-backface-visibility: hidden;
    -webkit-transform: translate3d(0,0,0);
    -moz-transform: translate3d(0,0,0);
    -ms-transform: translate3d(0,0,0);}

标头中引用了css文件，并在页脚中引用了javascript文件。

编辑：我在javascript文件中为导航设置了值0。现在箭已经出现了。但它们出现在旋转木马的中心。如何将它们放在正确的位置，即旋转木马左侧的前一个箭头和旋转木马右侧的下一个箭头。

Answer 1

我给你举个例子，但我用的是owl carousal 2

这里

var heroSlider = $('#header-slider');
heroSlider.owlCarousel({    
    margin:0,
    autoplay:true,
    autoplayTimeout:4000,
    smartSpeed:2000,
    dots:true,
    loop:true,      
    responsiveClass:true,
    items:1,
    rtl: true,
    nav: true,
     navText : ["<i class='fa fa-chevron-left'></i>","<i class='fa fa-chevron-right'></i>"],

});

对于正确的位置，我们需要设置箭头的位置。通过样式设置它们。

这样的事情

.owl-prev {
    left: 0;
    position: absolute;
}

.owl-next {
    position: absolute;
    right: 0;
}
