我在互联网上发现了这个简单的幻灯片,但问题在于它并没有重演。

我的意思是,它是从1到2,但是没有回到1.我需要在jQuery中修改什么?谢谢,这是我的第一篇文章。

JavaScript代码:

function slideSwitch() {
var mylenght = 5;
var $active = $('#slideshow IMG.active');

if ( $active.length == 0 ) $active = $('#slideshow IMG:last');
if ($active.length == mylenght) $active = $("#slideshow IMG:first")
// 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 );
});

答案 0 :(得分:0)

试试这个,

function slideSwitch() {
    var mylenght = 4;
    var $active = $('#slideshow IMG.active');

    if ($('#slideshow IMG').index($active) == mylenght - 1) 
        $next = $("#slideshow IMG:first")
    else
        $next = $active.next();


    $next.addClass('active').css({opacity: 0.0}).animate({opacity: 1.0}, 1000); 
    $active.removeClass('active').css({opacity: 1.0}).animate({opacity: 0}, 1000);
}
