Creating a Slideshow (^) ❘ 455


);


if (resetCounter)
{
counter = 1;
}

The value of the counter variable is moved to the counter property so that the slideshow can con-


tinue to function properly when it resumes automatically.


slideshows[slideCollection].counter = counter;

Then the slide the user clicked is faded in with an animation. The slide is referenced by its collection


number and its slide number.


$('#slide-' + slideCollection + '-' + slideInCollection)
.fadeIn(
'slow',
function()
{

The slideshowControlActive class name is added to the li variable holding a reference to the current


  • element’s jQuery object.
    li.addClass('slideshowControlActive');

    Now that the animation has completed, the transitioning property is set to false to indicate that


    there is no animation taking place right now.


    slideshows[slideCollection].transitioning = false;

    Because the animation has completed, the next step is to resume the timer. A call to setTimeout()


    triggers a slideshow transition to occur automatically after 5 seconds, as though the slideshow had


    never been interrupted. The next slide transition occurs after an additional 5 seconds.


    slideshows[slideCollection].resumeTimer = setTimeout(
    'slideshows[' + slideCollection + '].resume();',
    5000
    );
    }
    );
    }
    }
    );

    The next block of code is an API method. It resumes the slideshow if the slideshow has been


    interrupted.


    this.resume = function()
    {
    this.isInterrupted = false;
    this.transition();
    };
