使用jquery或其他JavaScript在指定的时间间隔格变化图像

Question

我想开发一个图像栅格使用jQuery或任何其他JavaScript手段在指定的时间间隔改变随机一些图像。请注意，我不需要所有的图像在同一时间改变。的图像的一个基团可以在不同的时间间隔相比于其他变化。

这些图像被定位绝对父DIV，以便它人们可以淡入，而其他淡出，直到它到达最后阶段。

我完全被卡住，而不在如何实现这一目标的想法。谁能帮我这个？以下是我的代码

(function(){
 let first = $('.column1 img:gt(0)');
  first.hide();
  let images = $('.column1').find('img');
  
  setInterval(function(){
    let current = $('.column1 img:visible');
    let next = current.next().length ? current.next():$('.column1 img:eq(0)');
    current.fadeOut(300);
    next.fadeIn(300);
  }, 3000);
});

#main__slider{
  width:40rem;
  height:25rem;
  margin: 0 auto;
  display:grid;
  grid-template-columns: repeat(3, 1fr);
  grid-template-rows: repeat(3, 1fr)
}

.column1{
  border:1px solid;
  position:relative;
}

img{
  width:100%;
  height:100%;
  object-fit:cover;
  position:absolute;
}

Answer 1

您需要创建一种循环像下面并考虑random()拥有的淡入淡出功能不同的时间：

$('.column1 img:eq(0)').each(function() {
  $(this).hide();
});

setInterval(function() {
  $('.column1 img:visible').each(function() {
    let next = $(this).next().length ? $(this).next() : $(this).parent().find('img:eq(0)');
    var t = Math.random()*2000;
    $(this).delay(t).fadeOut(500);
    next.delay(t).fadeIn(500);
  });
}, 3000);

#main__slider {
  width: 40rem;
  height: 25rem;
  margin: 0 auto;
  display: grid;
  grid-template-columns: repeat(3, 1fr);
  grid-template-rows: repeat(3, 1fr)
}

.column1 {
  border: 1px solid;
  position: relative;
}

img {
  width: 100%;
  height: 100%;
  object-fit: cover;
  position: absolute;
}
