我使用WooCommerce的Flexslider来浏览给定类别的许多帖子。此处可见：http://csl.nsta.org/development/
隐藏在图像后面的是滑块的“flex control导航”。。。设置样式后，这将显示为滑块底部的点；没有样式，它们只是一个编号列表，显示幻灯片的编号（1、2、3、4等），不要被帖子的ID混淆。
我正在尝试更改控件导航的内容，以显示帖子的标题，甚至可能是类别。
我认为这可以通过使用滑块中帖子的数据属性来完成，然后通过jquery获取这些属性。我的问题是，我不知道如何循环并获取这些帖子的每个属性。我想我需要做一些“foreach”的陈述？
从flexslider的jquery中，以下是控制导航的代码：
setupPaging: function() {
var type = (slider.vars.controlNav === "thumbnails") ? \'control-thumbs\' : \'control-paging\',
j = 1,
item,
slide;
slider.controlNavScaffold = $(\'<ol class="\'+ namespace + \'control-nav \' + namespace + type + \'"></ol>\');
if (slider.pagingCount > 1) {
for (var i = 0; i < slider.pagingCount; i++) {
slide = slider.slides.eq(i);
if ( undefined === slide.attr( \'data-thumb-alt\' ) ) { slide.attr( \'data-thumb-alt\', \'\' ); }
var altText = ( \'\' !== slide.attr( \'data-thumb-alt\' ) ) ? altText = \' alt="\' + slide.attr( \'data-thumb-alt\' ) + \'"\' : \'\';
item = (slider.vars.controlNav === "thumbnails") ? \'<img src="\' + slide.attr( \'data-thumb\' ) + \'"\' + altText + \'/>\' : \'<a href="#">\' + j + \'</a>\';
if ( \'thumbnails\' === slider.vars.controlNav && true === slider.vars.thumbCaptions ) {
var captn = slide.attr( \'data-thumbcaption\' );
if ( \'\' !== captn && undefined !== captn ) { item += \'<span class="\' + namespace + \'caption">\' + captn + \'</span>\'; }
}
slider.controlNavScaffold.append(\'<li>\' + item + \'</li>\');
j++;
}
}
在为滑块设置的循环中，标题是如何设置的，希望能够提取其数据属性：
<h2 data-title="<?php the_title(); ?>" title="<?php the_title(); ?>" class="slider-post-title"><a href="<?php the_permalink() ?>" rel="bookmark"><?php the_title(); ?></a></h2>
我想如果我能代替
j 使用某种类型的foreach变量
data-title 从标题中。
我不知道如何做到这一点。有什么建议吗？谢谢
edit: 滑块循环使用以下设置：
