carouFredSel slideTo / slideToPage事件 [英] carouFredSel slideTo/slideToPage events

问题描述

使用carouFredSel作为无限循环滑块时，我遇到了一些麻烦，控件可以转到特定的幻灯片。这是我的实现代码：

I'm having a bit of trouble with using carouFredSel as an infinite circular slider with controls to go to specific slides. Here is my implementation code:

$('.circular-gallery ul').carouFredSel({
    width: '100%',
    height:270,
    align:'center',
    items: {
        start: 10,
        width:340,
        visible: 10
    },
    prev: {
        button: $('.circular-gallery .prev')
    },
    next: {
        button: $('.circular-gallery .next')
    },
    scroll: {
        items: 1,
        easing: 'quadratic',
        onBefore: function(data){
            var $current = $(data.items.visible[4]);
            if(!data.scroll.duration){ // this happens on init, so just set active class
                $current.addClass('active');
            } else {
                var $active = $('.circular-gallery ul li.active');
                $active.find('.physician-name').fadeOut('normal', function(){
                    $(this).css('display','block').css('visibility','hidden');
                    $active.removeClass('active');
                });
                $current.find('.physician-name').css('visibility','visible').hide().fadeIn('normal', function(){
                    $current.addClass('active');
                });
            }
        }
    },
    auto: {
        play: false
    }
});

var $items = {};
$('.physician').hoverIntent(function(){
    slideToPhysician($(this).attr('rel'));
}, function(){ return false; });

function slideToPhysician(rel){
    var $items = $('.circular-gallery ul li').trigger('currentVisible');
    var index = $items.index($('li.'+rel));
    //console.log(index);
    //$('.circular-gallery ul').trigger('slideToPage', index);
    $('.circular-gallery ul').trigger('slideTo', index);
}

问题是每个元素的索引不是常量。每次滑块移动时它都会改变。所以我无法确定要滑到哪一个。我在我的滑块上有每个li的类，我在链接上使用rel属性将相应的类传递给hoverIntent事件。在调试过程中，如果我翻转相同的名字，我可能得到索引6，然后它滑到一些幻灯片，如果我再次翻转它，我得到10.我无法弄清楚模式或我是否正在做首先出现问题。

The problem is the index for each element is not constant. It changes each time the slider moves. So I'm having trouble determining which one to slide to. I have classes on each li in my slider and am using the "rel" attribute on my links to pass the corresponding class to the hoverIntent event. During debugging, if I rollover the same name, I might get the index of 6, then it slides to some slide, and if I rollover it again, i get 10. I can't figure out the pattern or if I'm doing something wrong in the first place.

也许我刚做错了什么，但目标是在页面中央有一个带突出显示项目的滑块然后，如果您将鼠标悬停在某个名称上几秒钟，滑块会移动到该特定照片。

Maybe I have just done something incorrectly, but the goal is to have a slider with the "highlighted" item in the center of the page, then if you hover over a name for a few seconds, the slider moves to that specific photo.

感谢您抽出宝贵时间提供帮助！

Thanks for taking your time to help!

推荐答案

我通过将数组作为参数传递给 slideTo 事件解决了几乎相同的问题。它包含点击的项目和carouFredSel项目索引：

I solved nearly the same problem with passing an array as parameter to slideTo Event. It contains the clicked item and the carouFredSel Item index:

$li.on('click', function() {
  var index = 0;
  $('#fred').trigger('slideTo', [$(this), index]);
});
