Question

我正在尝试重新加载滑块，以便拥有完全响应的布局。要做到这一点，我需要重新加载滑块！主要问题是滑块更改因为重新加载。因此，每次调整大小时，它都会从第一张幻灯片开始。

任何人都可以表明我的解决方案是在重新加载/调整大小时没有幻灯片的跳转吗？

var settings = function () {
    var settings1 = {
        pager: 'false',
        minSlides: 1,
        maxSlides: 1,
        startSlide: 1,
        moveSlides: 1,

        onSlideBefore:

        function (currentSlideNumber, totalSlideQty, currentSlideHtmlObject) {
            $('#carousel > li.active').removeClass('active');
            $('#carousel > li').eq(currentSlideHtmlObject - 1).addClass('active');
        },

        onSlideAfter: function (currentSlideNumber, totalSlideQty, currentSlideHtmlObject) {
            $('#carousel > li.active').removeClass('active');
            $('#carousel > li').eq(currentSlideHtmlObject + 1).addClass('active');
        },

        onSliderLoad: function (currentSlideHtmlObject) {
            $('#carousel').removeClass('settings2');
            $('#carousel').css('display', 'block').addClass('settings1');
            $('#carousel').fadeIn('slow');
            $('#carousel > li.active').removeClass('active');
            $('#carousel > li').eq(currentSlideHtmlObject + 1).addClass('active');

            $('.bx-controls').hover(

            function () {
                $('#carousel li a figure').addClass("hover").end();
            },

            function () {
                $('#carousel li a figure').removeClass("hover").end();
            });

        }

    };
    var settings2 = {

            },

            function () {
                $('#carousel li a figure').removeClass("hover").end();
            });

        }
    };
    return ($(window).width() < 1600) ? settings1 : settings2;
}

var mySlider;

function tourLandingScript() {
    mySlider.reloadSlider(settings());
}

mySlider = $('#carousel').bxSlider(settings());
$(window).resize(tourLandingScript);

您可以使用getCurrentSlide()存储当前幻灯片编号，并将其用作startSlide的开头。

现在只能在bxSlider对象上调用方法getCurrentSlide()。因此，必须在初始化bxSlider之后调用它，否则它将给出undefined值。这是之前发生的事情。所以我继续修改了一些代码来创建这个工作示例。

<html>
<head>
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script>
<script src="jquery.bxslider.min.js"></script>
<!-- bxSlider CSS file -->
<link href="jquery.bxslider.css" rel="stylesheet" />
<script>
$(document).ready(function(){
    var startnum=0,mySlider, settings1 = {
        pager:true,
        startSlide: 0,
        auto:false,
        useCSS:false,
        onSlideBefore:function (currentSlideNumber, totalSlideQty, currentSlideHtmlObject) {},
        onSlideAfter: function (currentSlideNumber, totalSlideQty, currentSlideHtmlObject) {},
        onSliderLoad: function (currentSlideHtmlObject) {}
    }, settings2 = {
        pager: false,
        startSlide: 0,
        auto:false,
        useCSS:false,
        onSlideBefore:function (currentSlideNumber, totalSlideQty, currentSlideHtmlObject) {},
        onSlideAfter: function (currentSlideNumber, totalSlideQty, currentSlideHtmlObject) {},
        onSliderLoad: function (currentSlideHtmlObject) {}
    };
    function settings() {return ($(window).width() < 1200) ? settings1:settings2;}
    mySlider=$('.bxslider').bxSlider(settings());
    function tourLandingScript() { 
        //alert(settings() +"   "+ mySlider.getCurrentSlide());
        mySlider.reloadSlider($.extend(settings(),{startSlide:mySlider.getCurrentSlide()}));
    }
    $(window).resize(tourLandingScript);
});
</script>
</head>

PS：

jsfiddle不会使用您在小提琴中添加的CDN链接加载bxslider。
当您使用自己的类时，请始终将useCSS:false传递给bxSlider对象，否则您可能会看到一些随机行为。
您可以取消注释tourLandingScript()中的注释行以验证值。另请注意，寻呼机在一个设置中启用，在另一个设置中关闭。
