获取图库下一个元素的href链接

Question

我需要获取newt / before元素的href来执行此操作：

  

＆lt; -a href =“$ url-of-next-or-before-element”   title =“$ title-of-next-or-before-element”＆gt;＆lt; -button title =“％title％”   type =“button”class =“mfp-arrow mfp-arrow-％dir％”＆gt; ＆LT; - /按钮＆GT;＆LT; - / A＆GT;

原始代码是：

$.magnificPopup.registerModule('gallery', {

    options: {
        enabled: false,
        arrowMarkup: '<-button title="%title%" type="button" class="mfp-arrow mfp-arrow-%dir%"></-button>',
        preload: [0,2],
        navigateByImgClick: true,
        arrows: true,

        tPrev: 'Previous (Left arrow key)',
        tNext: 'Next (Right arrow key)',
        tCounter: '%curr% of %total%' },

我该怎么做？
