我有以下代码,我的问题是如何添加,以便当用户单击链接时,滚动将被添加到类.instructors部分
<?php if($hasSections): ?>
                    <div class="instructors-links">
                        <?php foreach ($sections as $section): ?>
                            <a href="#section<?php echo $section['id']; ?>">
                                <div class="instructors-img">
                                    <img src="<?php echo $section['image']['url']; ?>" />
                                    <h2><?php echo $section['title']; ?></h2>
                                </div>
                            </a>
                        <?php endforeach; ?>
                    </div>
                    <div class="instructors">
                        <?php foreach ($sections as $section): ?>
                            <section id="section<?php echo $section['id']; ?>">
                                <h1 class="section-title"><?php echo $section['title']; ?></h1>
                                <div class="section-content">
                                    <?php echo $section['content']; ?>
                                </div>
                            </section>
                        <?php endforeach; ?>
                    </div>
                    <script type="text/javascript">
                        var $sections = jQuery('.instructors section'), //Each section of content
                            $sectionLinks = jQuery('.instructors-links a'); //Each section link
                        //When a section link <a> tag is clicked
                        $sectionLinks.click(function(e) {
                            e.preventDefault(); //prevent the default actions from happening like following the link and scrolling down to the content
                            changeSection(
                                jQuery(this).attr('href').replace('#', '') //Gets the href value of the clicked <a> tag and removes the "#" character
                            ); //Passes the section link to the "changeSection" function
                        });
                        changeSection('section1'); //When the page loads, display the "section1" section
                        function changeSection(sectionID) {
                            $sections.stop(true).hide(); //Stop animating and hide all sections
                            $sections.filter('#' + sectionID).stop(true).fadeIn(); //Display the section with the same ID as the section link that was clicked
                            $sectionLinks.removeClass('selected'); //Remove the selected class from all section link <a> tags
                            $sectionLinks.filter('[href="#' + sectionID + '"]').addClass('selected'); //Add the "selected" class to the section link that was clicked
                        }
                    </script>
                <?php endif; ?>其思想是,当用户单击链接时,文本会发生变化,页面会向下滚动到该文本。

这将动画滚动到“.instructors”部分。
 function changeSection(sectionID) {
        $sections.stop(true).hide(); //Stop animating and hide all sections
        $sections.filter('#' + sectionID).stop(true).fadeIn(); //Display the section with the same ID as the section link that was clicked
        $sectionLinks.removeClass('selected'); //Remove the selected class from all section link <a> tags
        $sectionLinks.filter('[href="#' + sectionID + '"]').addClass('selected'); //Add the "selected" class to the section link that was clicked
        $('html, body').animate({
            scrollTop: $sections.offset().top
        }, 2000);
