光滑的滑块-同步自动播放和主动导航 [英] slick slider - syncing autoplay and active navigation

问题描述

我正在尝试使用光滑的滑块创建一个滑块，该滑块允许用户选择该部分的标题并查看它的幻灯片，但还提供了使其自动播放的选项.

I am trying to use the slick Slider to create a slider that allows a user to select the title of the section and see the slide for it but also give the option for it to autoplay.

这些东西工作正常.但是我需要某种方式来制作它，以便当它自动播放时，它对应于活动的导航并更改其颜色.

The stuff works fine. But I need some way to correspond into make it so that when it autoplays, it corresponds to the active navigation and changes it color.

现在，如果用户单击它，则仅为活动的幻灯片标题显示新的颜色.我也想在自动播放中这样做

Right now it only show a new color for the active slide title if a user is clicking it. I want it to do so on autoplay also

我该怎么做?

这是我现在正在使用的代码

Here is the code I have working right now

Js Bin

我唯一更改的是光滑滑块的演示中不存在的自动播放选项

The only thing I changed is that autoplay option that does not exist on the demo of slick slider

 $('.slider-for').slick({
 slidesToShow: 1,
 slidesToScroll: 1,
 arrows: false,
 fade: true,
 asNavFor: '.slider-nav',
 autoplay:true

  });
$('.slider-nav').slick({
slidesToShow: 3,
slidesToScroll: 1,
asNavFor: '.slider-for',
dots: true,
centerMode: true,
focusOnSelect: true
});

$('.slider-for').slick({
    slidesToShow: 1,
    slidesToScroll: 1,
    arrows: false,
    fade: true,        
    autoplay:true,
    //trigger after the slide appears
    // i is current slide index
    onAfterChange:function(slickSlider,i){
         //remove all active class
         $('.slider-nav .slick-slide').removeClass('slick-active');
         //set active class for current slide
         $('.slider-nav .slick-slide').eq(i).addClass('slick-active');         
     }

});


//set active class to first slide
$('.slider-nav .slick-slide').eq(0).addClass('slick-active');
