Flexslider更改代码

Question

我使用WordPress。主题名称Wp-tuts。我的网站：http://www.memuralimi.com。

我使用滑块; Flexslider。当我用鼠标点击时，图像正在改变。

我希望当鼠标滑过缩略图时，图像会发生变化。

flexslider-home.js

jQuery(function($){
    $(window).load(function() {
        $('.featured-slider-preloader').hide();
        $('#featured-slider').flexslider({
            slideshow : true,
            controlsContainer: "#featured-slider-wrap",
            animation : 'fade',
            pauseOnHover: true,
            animationSpeed : 400,
            smoothHeight : true,
            directionNav: false,
            prevText : '<span class="fa fa-angle-left"></span>',
            nextText : '<span class="fa fa-angle-right"></span>',
            controlNav : "thumbnails"
        });
    });
});

内容功能-slider.php

<?php
$wpex_featured_cat = get_theme_mod( 'wpex_homepage_slider_cat' );
// Show homepage featured slider if theme panel category isn't blank
if( $wpex_featured_cat !== '' && $wpex_featured_cat !== '-1' ) {

    // Get posts based on featured category
    $wpex_query = new WP_Query( array(
        'post_type'         =>'post',
        'posts_per_page'    => get_theme_mod( 'wpex_homepage_slider_count', '6' ),
        'no_found_rows'     => true,
        'tax_query'         => array(
            'relation'      => 'AND',
            array(
                'taxonomy'  => 'category',
                'field'     => 'ID',
                'terms'     => $wpex_featured_cat
                )
            ),
        'meta_query'    => array(
            array(
                'key'   => '_thumbnail_id',
            )
        )
    ) );

    if( $wpex_query->have_posts() ) {

        // Get Scripts
        wp_enqueue_script( 'flexslider', WPEX_JS_DIR_URI .'/flexslider.js', array( 'jquery' ), '', true );
        wp_enqueue_script( 'wpex-flexslider-home', WPEX_JS_DIR_URI .'/flexslider-home.js', array( 'flexslider' ), '', true); ?>
