Jquery-to-如何始终显示“下一步”和“上一步”按钮？

大家好，我正在使用Jquery，我希望在弹出幻灯片上始终显示“下一步”和“上一步”按钮，而不是让用户将鼠标悬停在上面。我认为应该通过更改css来完成，但我不知道要更改哪个部分来始终显示按钮

      <script type="text/javascript" charset="utf-8">
        $(document).ready(function(){
            $("area[rel^='prettyPhoto']").prettyPhoto();

            $(".gallery:first a[rel^='prettyPhoto']").prettyPhoto({animation_speed:'slow',theme:'light_squarex',slideshow:3000, autoplay_slideshow: false});
            $(".gallery:gt(0) a[rel^='prettyPhoto']").prettyPhoto({animation_speed:'slow',slideshow:10000, hideflash: true});



            $("#custom_content a[rel^='prettyPhoto']:first").prettyPhoto({
                custom_markup: '<div id="map_canvas" style="width:260px; height:265px"></div>',
                changepicturecallback: function(){ initialize(); }
            });

            $("#custom_content a[rel^='prettyPhoto']:last").prettyPhoto({

您必须更改这些CSS选择器：

div.light_squarex.pp_next:悬停{背景：url（../images/prettypto/light_square/btnNextplay.png）右下角不重复；光标：指针；}/*下一步按钮*/

div.light_squarex.pp_previous:悬停{背景：url（../images/prettypto/light_square/btnPrevious.png）左下角不重复；光标：指针；}/*previous按钮*/

只需删除：鼠标悬停，默认情况下，箭头将显示，而无需鼠标悬停。

尝试此操作，指向图像的普通图库链接将显示以下内容：

<a href="assets/img/portfolio/work8.jpg" rel="prettyPhoto">

将其更改为：

<a href="assets/img/portfolio/work8.jpg" rel="prettyPhoto[gallery]">

rel=“prettypto[gallery]”将确保所有具有该[]的图像都将分组，从而在默认情况下显示下一个图像和后一个图像

如果没有它，它只会显示带有一个图像的灯箱。

谢谢！从Prettypto更改为Prettypto[gallery]带来了导航功能
