javascript - jQuery:滑出并滑入下一个元素并循环？

Question

我正在尝试使用 jquery 滑出，然后滑入下一个元素并循环。

目前我可以将元素滑出，但下一个元素无法滑入。

这是一个工作FIDDLE

这是我的代码:

$( "#SLIDE" ).click(function() {
var widths = $('.some').width();


 $(".some")
    .first()
    .animate({ "margin-left": widths }, "slow" )
    .next()
    .animate({ "margin-left": 0 }, "slow" )
    .end();


}); 

有人可以就此提出建议吗？

提前致谢

希望这篇文章能帮到你。

$(function() {
  // count your slide elements
  var elementCount = $('.some').length;
  // width of the first element
  var width = $('.some').first().width();
  // full width of all elements
  var fullWidth = elementCount*width;
  // scroll left value
  var scrollLeft = width;

  // update values after resizing
  $(window).on('resize', function() {
    width = $('.some').first().width();
    scrollLeft = width;
    fullWidth = elementCount*width;
    $("#feedTxt").scrollLeft(0);
  });

  
  $("#SLIDE").click(function() {

    // if full width smaller or equal to your scroll left, than scroll to the beginning
    if((fullWidth) <= scrollLeft) {
      scrollLeft = 0;
    }

    // animate scroll left
    $("#feedTxt").animate({scrollLeft: scrollLeft}, 800);

    // if the full width not equal to scroll left, add width to scrollLeft
    if((fullWidth) !== scrollLeft) {
      scrollLeft += width;
    }
  });	
});

#feedTxt {
    display: flex;
    overflow-x: scroll;
    height:450px;
    width:100%;
}

.some {
    flex: 0 0 100%;
    height: 450px;
}
