调整大小时滑块全宽

标签: javascript jquery html css

我正在研究这个滑块: http://codepen.io/anon/pen/viBHe

当您打开页面时,滑块获得100%的屏幕宽度,这是正常的,我想要实现但问题是当您调整大小并使屏幕更大,然后显示下一张幻灯片,如下所示:

有关如何保持100% width调整屏幕大小的任何想法?

另外,有人知道为什么从最后一张幻灯片开始吗?

这是我正在使用的脚本:

jQuery(document).ready(function ($) {

  $('#checkbox').change(function(){
    setInterval(function () {
        moveRight();
    }, 3000);
  });

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

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

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

  $('#slider ul li').css({ width: slideWidth });

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

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

    function moveRight() {
        $('#slider ul').animate({
            left: - slideWidth
        }, 400, function () {
            $('#slider ul li:first-child').appendTo('#slider ul');
            $('#slider ul').css('left', '');
        });
    };

    $('a.control_prev').click(function () {
        moveLeft();
    });

    $('a.control_next').click(function () {
        moveRight();
    });

});

尝试将px添加到@SauriolJf发布的答案

$(window).resize(function(){
    $('li').css({"width":$(window).width()+"px"});
});

对于滑块的宽度,您可以使用.resize()触发窗口的大小调整。每次调整窗口大小时,都会重新调整幻灯片的宽度。

$(window).resize(function(){
    $('div').css({"width":$(window).width()});
});

Here's a fiddle ,调整窗口大小以确定div始终为宽度的100%。
