Share an example of JS native carousel image

My friends, I have a new project recently. So there has been no update! did you miss me! !

Today let’s talk about JS native carousel images!

Not much to say:

Let’s go directly to the code: the following is the CSS part:

*{
    padding: 0px;
    margin: 0px;
   }
   img{
    width: 500px;
    height: 300px;
   }
   li{
    float: left;
   }
   ul{
    width: 2000px;
    list-style: none;
    position: absolute;
   }
   p{
    width: 500px;
    height: 300px;
    /*溢出部分隐藏*/
    overflow: hidden;
    margin: 60px auto;
    position: relative;
   }

HTML part!

<p>
 <ul>
  <li><img src="img/1.jpg" /></li>
  <li><img src="img/2.jpg"/></li>
  <li><img src="img/3.jpg"/></li>
  <li><img src="img/1.jpg" /></li>
 </ul>
</p>

Next is the JS part:

//1、获取到ul
   var ul = document.getElementsByTagName("ul")[0];
   var x = 0;
   
   //id 用来关闭定时器的
   var id = setInterval(abc,10);
   
   function abc(){
    ul.style.left = x-- +"px";
    
    //如果到第三周图片了
    if(x == -1500){
     x = 0;//把ul修改成第一张图片
     ul.style.left = x+"px";
    }
    if(x % 500 == 0){ //第一张图片进来
     clearInterval(id); //关闭定时器
     //开启定时器 隔半秒钟开启定时器
     setTimeout(function(){
      //500毫秒之后开启定时器，继续执行
      id = setInterval(abc,10);
     },500);//setTimeout 延时执行
    }
   }

It’s that simple! Have you learned it? ?
