Question

我有以下代码，我的问题是我将如何添加到此以便当用户点击链接时添加滚动以便将它们带到类.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; ?>

这个想法是，当用户点击链接时，文本会发生变化，页面会向下滚动到文本。

Answer 1

这应该会动画滚动到＆＃39; .instructors部分＆＃39;

 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);

  }

Answer 2

我创建了一个＆＃34;帮助＆＃34; JS中关于滚动的函数

function goToByScroll (id) {
    // Reove "link" from the ID
    id = id.replace("link", "");
    // Scroll
    $('html,body').animate({
        scrollTop: $("#" + id).offset().top
    },
        'slow');
}

你应该传递id并且会工作。

goToByScroll('section1');

应该在此ID中找到窗口

滚动到部分
