What is this bar called?

Solved Customisation
  • @DownPW hmm. Odd. I’ll have to take a look at that. Not seeing that here and I think that’s the same for @cagatay

  • @DownPW Can you try with this code?

    // Scroll to top function
    $(window).on('action:ajaxify.end', function(data) {
        var matched = false;
        $(document).ready(function() {
            var pageUp = $('#pageUp');
            var bar = $('.reading-meter');
            var perWidth = $('.reading-meter').width();
            
            // Main progressbar function
            function pageScroller() {
                var winScroll = document.body.scrollTop || document.documentElement.scrollTop;
                var height = document.documentElement.scrollHeight - document.documentElement.clientHeight;
                var scrolled = (winScroll / height) * 100;
    
                document.getElementById("progress-bar").style.width = parseFloat(scrolled).toFixed(0) + "%";
                $('#percentage').val(parseFloat(scrolled).toFixed(0) + "%");
    
                // Prevent the mouse scroll wheel from scrolling down after the pageUp button is clicked
                if ($('#pageUp').is(':focus')) {
                    event.preventDefault();
                }
            }
    
            // Bind the pageScroller function to the window's scroll event
            $(window).scroll(function() {
                pageScroller();
            });
    
            // Check the URL and composer visibility separately from the scroll event
            function checkURL() {
                var thisURL = window.location.href;
                var checkArray = ["topic", "notifications", "user"];
                var isFound = false;
                
                for (var i = 0, len = checkArray.length; i < len; i++) {
                    if (thisURL.indexOf(checkArray[i]) > -1) {
                        isFound = true;
                        break;
                    }
                }
                
                return isFound;
            }
    
            // Function to update visibility based on URL and composer
            function updateVisibility() {
                if (checkURL()) {
                    bar.removeClass('show');
                    pageUp.removeClass('show');
                } else {
                    // Exception here is that we don't want the scroll bar to show when the composer is active
                    if ($(window).scrollTop() > 0 && (!$('[component="composer"]').is(":visible"))) {
                        bar.addClass('show');
                        pageUp.addClass('show');
                    } else {
                        bar.removeClass('show');
                        pageUp.removeClass('show');
                    }
                }
            }
    
            // Call updateVisibility initially
            updateVisibility();
    
            // Bind updateVisibility function to the window's scroll event
            $(window).scroll(function() {
                updateVisibility();
            });
        });
    });
    
    
  • seems to be good my friend 🙂

  • @DownPW not sure if you’ve noticed, but (at least for me) the scroll to top function no longer works?

    EDIT - there is a bug in the above code. Please use this updated version

    // Scroll to top function
    $(window).on('action:ajaxify.end', function(data) {
        var matched = false;
        $(document).ready(function() {
            var pageUp = $('#pageUp');
            var bar = $('.reading-meter');
            var perWidth = $('.reading-meter').width();
            
            // Main progressbar function
            function pageScroller() {
                var winScroll = document.body.scrollTop || document.documentElement.scrollTop;
                var height = document.documentElement.scrollHeight - document.documentElement.clientHeight;
                var scrolled = (winScroll / height) * 100;
    
                document.getElementById("progress-bar").style.width = parseFloat(scrolled).toFixed(0) + "%";
                $('#percentage').val(parseFloat(scrolled).toFixed(0) + "%");
    
                // Prevent the mouse scroll wheel from scrolling down after the pageUp button is clicked
                if ($('#pageUp').is(':focus')) {
                    event.preventDefault();
                }
            }
    
            // Bind the pageScroller function to the window's scroll event
            $(window).scroll(function() {
                pageScroller();
            });
    
            // Check the URL and composer visibility separately from the scroll event
            function checkURL() {

                        break;
                    }
                }
                
                return isFound;
            }

  • It’s funny I just realized it and I was going to share it here and I see your message!!
    Thanks you Mark @phenomlab 😉

    On the other hand, I have never been careful but I have the impression that the page is reloaded when you click on the button.
    I don’t know if it’s me but before, (on v2 perhaps?) we saw the page scroll from bottom to top after pressing the button

    I find this strange. I’ve never seen this on other sites using the same type of scroll to top

  • @DownPW you are right - it used to scroll to the top but I changed it because “scroll top” actually only applied to what was in the DOM at the time meaning that as data was being added, the “top” position was no longer a true representation and so the button had to be clicked multiple times to reach the “real” top.

  • Ok, thanks to confirm 🙂
    so I have no possibility of modifying it to display the same effect as on v2?

  • @DownPW it can easily be reverted, but I don’t want to maintain two sets of code. I’ll defer to others here for that final decision as I know it did cause some confusion.

  • no problem dude @phenomlab 🙂
    I put a modification here that seems to work as a reminder if you don’t mind.

    –> If yes, you can delete it.

    use $('html, body').animate({ scrollTop: 0 }, '300'); to smoothly scroll the page to the top when the #pageUp button is clicked. This code will provide a smooth scrolling effect from the bottom to the top of the page without reloading it.

    What do you think of this?

    // Scroll to top function
    $(window).on('action:ajaxify.end', function(data) {
        var matched = false;
        $(document).ready(function() {
            var pageUp = $('#pageUp');
            var bar = $('.reading-meter');
            var perWidth = $('.reading-meter').width();
            
            // Main progressbar function
            function pageScroller() {
                var winScroll = document.body.scrollTop || document.documentElement.scrollTop;
                var height = document.documentElement.scrollHeight - document.documentElement.clientHeight;
                var scrolled = (winScroll / height) * 100;
    
                document.getElementById("progress-bar").style.width = parseFloat(scrolled).toFixed(0) + "%";
                $('#percentage').val(parseFloat(scrolled).toFixed(0) + "%");
    
                // Prevent the mouse scroll wheel from scrolling down after the pageUp button is clicked
                if ($('#pageUp').is(':focus')) {
                    event.preventDefault();
                }
            }
    
            // Bind the pageScroller function to the window's scroll event
            $(window).scroll(function() {
                pageScroller();
            });

                        break;
                    }
                }
                
                return isFound;
            }
    
            // Function to update visibility based on URL and composer
            function updateVisibility() {
                if (checkURL()) {
                    bar.removeClass('show');
                    pageUp.removeClass('show');

                        pageUp.addClass('show');
                    } else {
                        bar.removeClass('show');
                        pageUp.removeClass('show');
                    }
                }
            }
    
            // Call updateVisibility initially
            updateVisibility();
    
            // Bind updateVisibility function to the window's scroll event
            $(window).scroll(function() {
                updateVisibility();
            });
    
            // Scroll to top when #pageUp is clicked
            $(document).on("click", "#pageUp", function(e) {
                $('html, body').animate({ scrollTop: 0 }, '300'); // Animate scrolling to top
                $('#progress-bar').width(0);
                pageUp.removeClass('show');
            });
        });
    });
    
  • @DownPW looks good to me.

  • @DownPW Just to circle back to this, the decision to reload the page instead of multiple scrolling / clicking was based on this discussion, which I’m including here for brevity

  • @phenomlab said in What is this bar called?:

    @DownPW you are right - it used to scroll to the top but I changed it because “scroll top” actually only applied to what was in the DOM at the time meaning that as data was being added, the “top” position was no longer a true representation and so the button had to be clicked multiple times to reach the “real” top.

    you are right @phenomlab the code I gave yesterday works but does the same thing as you described.

    here a mix of the 2 (scroll to top & scroll to top with refresh)

    // Scroll to top function (classic scroll to top)
    $(window).on('action:ajaxify.end', function(data) {
        var matched = false;
        $(document).ready(function() {
            var pageUp = $('#pageUp');
            var bar = $('.reading-meter');
            var perWidth = $('.reading-meter').width();
            
            // Main progressbar function
            function pageScroller() {
                var winScroll = document.body.scrollTop || document.documentElement.scrollTop;
                var height = document.documentElement.scrollHeight - document.documentElement.clientHeight;
                var scrolled = (winScroll / height) * 100;
    
                document.getElementById("progress-bar").style.width = parseFloat(scrolled).toFixed(0) + "%";
                $('#percentage').val(parseFloat(scrolled).toFixed(0) + "%");
    
                // Prevent the mouse scroll wheel from scrolling down after the pageUp button is clicked
                if ($('#pageUp').is(':focus')) {
                    event.preventDefault();

                // No need to check composer visibility for these routes
                if ($(window).scrollTop() > 0) {
                    bar.addClass('show');
                    pageUp.addClass('show');
                } else {
                    bar.removeClass('show');
                    pageUp.removeClass('show');
                }
            }
    
            // Call updateVisibility initially
            updateVisibility();
    
            // Bind updateVisibility function to the window's scroll event
            $(window).scroll(function() {
                updateVisibility();
            });
    
            // Scroll to refresh when #pageUp is clicked
            $(document).on("click", "#pageUp", function(e) {
                ajaxify.refresh();
                $('#progress-bar').width(0);
                pageUp.removeClass('show');
            });
        }
    });
    

    I found it interesting to keep the scroll effect on the home page

    The scroll to top with refresh is applied on the routes indicated in the script (/recent, /unread, etc.). The classic scroll to top applies to other pages and the scroll to top is disabled in chat, etc…

    For the previous script, I used the code from your v2 and doing myself but I’m not being a good JS developer, so this time I asked to ChatGPT to help me, sorry !

    I tested the code and it seems to work correctly without any bugs but could you check @phenomlab if this seems correct to you even if the code works?

    A machine will not replace humans in this regard. At least for now 🙂

  • @DownPW 🙂 Love it - let me try this out!

    EDIT - Tried it, and there’s a couple of bugs. For example, if you use a custom page, scroll to the bottom, then use the back to top button, you have to scroll the mouse wheel down 16 times (if you do it quickly - depending on intervals it can be much less) before it’ll work properly. This is animation jitter as far as I can see where the animation does not complete on time and is therefore stuck in a loop.

    Have a look yourself here and see if you get the same experience

  • Seems you can fix this by using e.preventDefault() see below

        // Scroll to top when #pageUp is clicked
        $(document).on("click", "#pageUp", function(e) {
            e.preventDefault(); // Prevent default behavior
            $('html, body').animate({ scrollTop: 0 }, '300'); // Animate scrolling to top
            $('#progress-bar').width(0);
            pageUp.removeClass('show');
        });
    
  • Not test on custom page. Test ASAP

  • @DownPW said in What is this bar called?:

    Not test on custom page. Test ASAP

    The above code change I provided seems to resolve the issue.

  • This is good 👍

    @crazycells it is, yes - I think I’ll leave it as there is no specific PWA CSS classes I know of. Well, you could use something like the below, but this means multiple CSS files for different operating systems.

    /** * Determine the mobile operating system. * This function returns one of 'iOS', 'Android', 'Windows Phone', or 'unknown'. * * @returns {String} */ function getMobileOperatingSystem() { var userAgent = navigator.userAgent || navigator.vendor || window.opera; // Windows Phone must come first because its UA also contains "Android" if (/windows phone/i.test(userAgent)) { return "Windows Phone"; } if (/android/i.test(userAgent)) { return "Android"; } if (/iPad|iPhone|iPod/.test(userAgent) && !window.MSStream) { return "iOS"; } return "unknown"; // return “Android” - one should either handle the unknown or fallback to a specific platform, let’s say Android }

    Once you’re in that rabbit hole, it’s impossible to get out of it.

    @riekmedia I’ve applied some new CSS to your site. Can you reload the page and try again ?

    For the record, this is what I added

    #footer { background: #2d343e; border-top: 4px solid #2d343e; font-size: 0.9em; margin-top: 70px; padding: 80px 0 0; position: relative; clear: both; bottom: 0; left: 0; right: 0; z-index: 1000; margin-left: -15px; margin-right: -338px; }

    The /categories page seems a bit messed up, so looking at that currently

    EDIT - issued some override CSS in the CATEGORIES widget

    <!--- CSS fix for overspill on /categories page - DO NOT DELETE --> <style> #footer { margin-right: -45px; } </style>

    That should resolve the /categories issue.
