嗨我需要爲我的幻燈片放映創建if語句,如果只有一個圖像我不希望幻燈片顯示爲活動狀態;Jquery褪色幻燈片如果語句
的Javascript:
<script type="text/javascript">
function slideSwitch() {
var $active = $('#slideshow IMG.active');
if ($active.length == 0) $active = $('#slideshow IMG:last');
// use this to pull the images in the order they appear in the markup
var $next = $active.next().length ? $active.next()
: $('#slideshow IMG:first');
// uncomment the 3 lines below to pull the images in random order
// var $sibs = $active.siblings();
// var rndNum = Math.floor(Math.random() * $sibs.length);
// var $next = $($sibs[ rndNum ]);
$active.addClass('last-active');
$next.css({opacity: 0.0})
.addClass('active')
.animate({opacity: 1.0}, 1000, function() {
$active.removeClass('active last-active');
});
}
$(function() {
setInterval("slideSwitch()", 5000);
});
</script>
HTML:
<div id="slideshow">
<img src="image1.jpg" class="active" />
JS是不是真的是我的強項,任何幫助將是巨大的!
正常使用!!!! – MrThomas
