我使用flexslider作为我的Wordpress主题，但无论我做什么，滑块都不会出现在我的网站上。
这是使用flexslider http://www.woothemes.com/flexslider/
的使用说明我在js文件夹中添加了jquery.flexslider.js文件，在css文件夹中添加了flexslider.css。
我刚刚按照说明操作，但我没有得到幻灯片。我得到的只是一个小的拉伸空矩形。
头部内部：header.php
<script type="text/javascript" charset="utf-8">
$(window).load(function() {
$('.flexslider').flexslider();
});
</script>
带有flexslider类和无序列表的div：
<div id="featured" class="clearfix flexslider">
<ul class="slides">
<?php
$args = array(
'post_type' => 'work'
);
$the_query = new WP_Query($args);
?>
<?php if (have_posts()) : while ( $the_query->have_posts() ) : $the_query->the_post(); ?>
<li style="background-color: <?php the_field('background_color'); ?>">
<div class="container">
<div class="grid_8">
<img src="<?php the_field( 'homepage_slider_image'); ?>" alt = "<?php the_title();?> Project Screenshot">
</div>
<div id="featured-info" class="grid_4 omega">
<h5>Featured Project</h5>
<h3 style="color: <?php the_field('button_color'); ?>">
<?php the_title(); ?>
</h3>
<p><?php the_field('description'); ?></p>
<a class="btn" style="background-color: <?php the_field('button_color'); ?>" href="#">View Project →</a>
</div>
</div>
</li>
<?php endwhile; endif; ?>
</ul>
</div>
