"Using the ScrollTo function will smoothly move the view beyond the

Currently, my contact form is functioning well with jQuery verification instead of AJAX due to a lack of development time. However, I now want the page to scroll down automatically when there are errors in the form. To achieve this, I have included jquery.scrollTo.js in my header.php file and added the following script for scrolling:

if ($("#front_page_contactformulier span").hasClass("error")) {
    $('body').scrollTo('#fp_content_006',4000);
}

The strange thing is that when the

#front_page_contactformulier span
has the class error, it scrolls past the intended element (almost to the bottom of the page).

If I modify the script to target a different element like so:

if ($("#front_page_contactformulier span").hasClass("error")) {
    $('body').scrollTo('#fp_content_005',4000);
}

It works perfectly fine?

I'm struggling to figure out why this discrepancy exists. Below is the complete code:

HTML:

<section id="fp_content_006">
    <div class="container">
        <div class="col-xs-12 col-sm-12 col-md-12 col-lg-12">
            <article>
                <?php if( get_field('koptekst_6') ): ?>
                    <h2><?php the_field('koptekst_6'); ?></h2>
                    <div style="display:block;height:2px;width:30px;background:#f60;margin-left:auto;margin-right:auto;margin-bottom:15px;margin-top:15px;"></div>
                <?php endif; ?>
                <?php if( get_field('content_koptekst_6') ): ?>
                    <?php the_field('content_koptekst_6'); ?>
                <?php endif; ?>
            </article>
        </div>
        <div class="col-xs-12 col-sm-12 col-md-12 col-lg-12">
            <div class="row">
                <div id="front_page_contactformulier">
                    <span class="error">Error</span>
                </div>
            </div>
        </div>
    </div>
</section>

CSS:

#fp_content_006 {
    position:relative;
    margin-bottom:90px;
    text-align:center;
    margin-top:90px;
}

jQuery:

if ($("#front_page_contactformulier span").hasClass("error")) {
    $('body').scrollTo('#fp_content_006',4000);
}

Furthermore, the functionality can be viewed on this JSFiddle link. It's worth noting that it surprisingly works on this platform.

Answer №1

Make sure to properly include jquery.scrollTo.js in your header.php file and keep in mind the following advice from PHP documentation:

Always remember that header() should be called before any content is outputted, whether it's HTML tags, white spaces in a file, or PHP code. It's a common error to have include functions, require functions, or any other file access function with extra spaces or empty lines that are displayed before calling header(). This issue can also occur when using only one PHP/HTML file.

Answer №2

After reviewing the JS code you provided, let me explain it in simpler terms:

if ($("#front_page_contactformulier span").hasClass("error")) {
    $('body').scrollTo('#fp_content_006',4000);
}

To clarify, the first argument should be a jQuery object and you simply need to wrap your selector with a jQuery object like this:

    $('body').scrollTo($('#fp_content_006'),4000);

According to the documentation available here, there are several other methods for scrolling besides using a selector.

Additionally, I would like to point out that a duration of 4000 for the animation seems quite long. I would suggest adjusting it to a range between 300 to 800 for better user experience.
