jquery实现简单的自动播放幻灯片效果

<div id="slideshow">
  <div>
   <img src="/UploadFiles/2021-04-02/5658667829_2bb7d42a9c_m.jpg">

/* Slides need to be absolutely positioned within the wrapper.
This has a tiny bit of extra pizazz: */
#slideshow {
  margin: 50px auto;
  position: relative;
  width: 240px;
  height: 240px;
  padding: 10px;
  box-shadow: 0 0 20px rgba(0,0,0,0.4);
}
#slideshow > div {
  position: absolute;
  top: 10px;
  left: 10px;
  right: 10px;
  bottom: 10px;
}


jQuery部分：


//Run after DOM is ready.
$("#slideshow > div:gt(0)").hide();
setInterval(function() {
 $('#slideshow > div:first')
  .fadeOut(1000)
  .next()
  .fadeIn(1000)
  .end()
  .appendTo('#slideshow');
}, 3000);
