Tutorial : Buat Jquery Features Image Slideshow

Tutorial : Buat Jquery Features Image Slideshow:

Contoh slideshow

Sebelum ini saya ada berkongsi tutorial berkaitan macammana nak edit HTML iaitu lebih kepada untuk edit slideshow yang dah sedia ada di dalam template yang disediakan seperti slideshow saya sebelum ini.

Tutorial kali ini pula bagi korang yang pilih template yang tidak datang sekali dengan template slideshow. Korang boleh juga buat slideshow korang sendiri. Slideshow ni menggunakan JQuery. Caranya mudah sahaja. Jom kita tengok cara-cara untuk buat slideshow ni.

1. Pergi ke Dashboard > Design > Page Elements > Add a Gadget

2 Salin code di bawah dan letakkannya di HTML/Javascript

<script src='http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js' type='text/javascript'>script>

<script type='text/javascript'>

$(document).ready(function() {

//Execute the slideShow, set 6 seconds for each images

slideShow(3000);

});

function slideShow(speed) {

//append a LI item to the UL list for displaying caption

$('ul.slideshow').append('<li id="slideshow-caption" class="caption"><div class="slideshow-caption-container"><h3>h3><p>p>div>li>');

//Set the opacity of all images to 0

$('ul.slideshow li').css({opacity: 0.0});

//Get the first image and display it (set it to full opacity)

$('ul.slideshow li:first').css({opacity: 1.0});

//Get the caption of the first image from REL attribute and display it

$('#slideshow-caption h3').html($('ul.slideshow a:first').find('img').attr('title'));

$('#slideshow-caption p').html($('ul.slideshow a:first').find('img').attr('alt'));

//Display the caption

$('#slideshow-caption').css({opacity: 0.7, bottom:0});

//Call the gallery function to run the slideshow

var timer = setInterval('gallery()',speed);

//pause the slideshow on mouse over

$('ul.slideshow').hover(

function () {

clearInterval(timer);

},

function () {

timer = setInterval('gallery()',speed);

}

);

}

function gallery() {

//if no IMGs have the show class, grab the first image

var current = ($('ul.slideshow li.show')? $('ul.slideshow li.show') : $('#ul.slideshow li:first'));

//Get next image, if it reached the end of the slideshow, rotate it back to the first image

var  next = ((current.next().length) ? ((current.next().attr('id') ==  'slideshow-caption')? $('ul.slideshow li:first') :current.next()) :  $('ul.slideshow li:first'));

//Get next image caption

var title = next.find('img').attr('title');

var desc = next.find('img').attr('alt');

//Set the fade in effect for the next image, show class has higher z-index

next.css({opacity: 0.0}).addClass('show').animate({opacity: 1.0}, 1000);

//Hide the caption first, and then set and display the caption

$('#slideshow-caption').animate({bottom:-70}, 300, function () {

//Display the content

$('#slideshow-caption h3').html(title);

$('#slideshow-caption p').html(desc);

$('#slideshow-caption').animate({bottom:0}, 500);

});

//Hide the current image

current.animate({opacity: 0.0}, 1000).removeClass('show');

}
