How to remove slick slide on mobile?

问题

I'm using the awesome Slick slide on a project.

The problem is: I have a carousel with 5 divs inside. 4 images and a video.

On mobile (< 768px) I want the slider to show only the images, not the video. I tried to hide the video div by css but that's not working.

Any ideas on how to do this? Anyone had this need before?

回答1:

Look at the «Filtering» demo at the Slick's documentation. Let's use it to solve the issue.

Set breakpoints that you need, using the responsive option.
Catch the breakpoint event and read the activeBreakpoint property of the carousel. Notabene: when the screen width is greater than the last of the breakpoints, this property returns null.
Call slickFilter and slickUnfilter methods:

slickFilter
Argument filter: selector or function
Filters slides using jQuery .filter syntax

slickUnfilter
Removes applied filter
Beware of an infinite loop: these methods cause a re-initialization of the slider, during which the breakpoint event again occurs (unless the breakpoint is null).
Call these methods during initialization too. Don’t forget to define the init handler before the initialization.

Slides with the .hide-on-mobile class become hidden when the screen width is 700px or less.

var breakpointMobile = 700,
    isChanging = false,
    isFiltered = false;
$('#breakpointMobile').text( breakpointMobile );

$('#myCarousel').on('init breakpoint', function(event, slick){  /** 2. and 5. **/
  if ( ! isChanging ) {                                         /** 4. **/
    $('#breakpointValue').text( String(slick.activeBreakpoint) );
    isChanging = true;
    if ( slick.activeBreakpoint && slick.activeBreakpoint <= breakpointMobile) {
      if ( ! isFiltered ) {
        slick.slickFilter(':not(.hide-on-mobile)');             /** 3. **/
        isFiltered = true;
      }
    } else {
      if ( isFiltered ) {
        slick.slickUnfilter();
        isFiltered = false;
      }
    }
    isChanging = false;
  }
}).slick({
  autoplay: true,
  dots: true,
  responsive: [                                                 /** 1. **/
    { breakpoint: 500 },
    { breakpoint: 700 },
    { breakpoint: 900 }
  ]
});

body {                                                          /** Decorations **/
  font-family: 'Open Sans', sans-serif;
}
.my-carousel img {
  width: 100%;
}
.my-carousel .slick-next {
  right: 15px;
}
.my-carousel .slick-prev {
  left: 15px;
  z-index: 1;
}

回答2:

Slick has the method slickRemove (you have to scroll down a bit):

Remove slide by index. If removeBefore is set true, remove slide preceding index, or the first slide if no index is specified. If removeBefore is set to false, remove the slide following index, or the last slide if no index is set.

I would just call this method and remove the slide with the video if your current screen size is lower than 768px.
