    var sliderUlWidth = slideCount * slideWidth;

    $('#slider').css({ width: slideWidth, height: slideHeight });

    $('#slider ul').css({ width: sliderUlWidth, marginLeft: - slideWidth });

    $('#slider ul li:last-child').prependTo('#slider ul');

    function moveLeft() {
        $('#slider ul').animate({
            left: + slideWidth
        }, 200, function () {
            $('#slider ul li:last-child').prependTo('#slider ul');
            $('#slider ul').css('left', '');
        });
    };

    function moveRight() {

您可以使用文档的宽度计算li的宽度,并且将处理ul的宽度。

<强> JS

    //get width of document here and set to li
    $('#slider ul li').css({"width":($(document).width()-200)});

    var slideCount = $('#slider ul li').length;
    var slideWidth = $('#slider ul li').width();
    var slideHeight = $('#slider ul li').height();
    var sliderUlWidth = slideCount * slideWidth;

    $('#slider').css({ width: slideWidth, height: slideHeight });


    $('#slider ul').css({ width: sliderUlWidth, marginLeft: - slideWidth });

<强> CSS

#slider ul li { 

    /* other CSS */

    height: 100%;

  }

并且图像对父母的反应

#slider ul li img { 
 max-width: 100%;
 max-height: 100%;
}
