PHP Slide Show Bug

  • # February 8, 2013 at 2:33 pm

    Greetings

    I have a slide show on our website that was built by a friend who hit a stumbling block on this bug. I was hoping someone may recognize the issue.

    The website is http://www.KarenImages.com. Each page has a slide show. When a page is open and running in a browser and you open a new tab and browse that tab & then come back a minute or so later the slide show quickly does a catch up pattern rapidly playing all the images missed while on the other tab in order to catch up to where it is supposed to be. Codepen did not have a php option so I did not create one for this (newbie). The code for the home page slide show is pasted her – each page has a unique image directory and php file that is behaving the same way. this php code is from the file “home-fading.php”

    Second issue is the slide show is warping the images slightly in the horizontal dimension…I am thinking this is an image size issue???

    Any ideas greatly appreciated!

    First issue is a JavaScript issue. I think the `setInterval()` function calls build up when tabbed. You can try changing:

    $(function() {
    setInterval( “slideSwitch()”, 5000 );
    });

    into

    $(function() {
    var id = setInterval(slideSwitch, 5000);
    $(window).blur(function(){
    clearInterval(id);
    });
    $(window).focus(function(){
    id = setInterval(slideSwitch, 5000);
    });
    });

    to cancel the interval when the window loses focus and resume when it gains focus. (I haven’t tested this but it could work)
