I completely stuck with slider with url links inside the Array. How to make this code run appropriate? This is it: https://codepen.io/konradszymanski/pen/VwvLgYG?editors=0110

或者这里是html:

<script src='https://kit.fontawesome.com/a076d05399.js'></script>
  <div class="container">
    <button class="left" onclick="" ><i class='fas fa-angle-left'></i></button>
    <button class="right" onclick="next()"><i class='fas fa-angle-right'></i></button>
  </div>

和js:

 var images  = [{img: "https://upload.wikimedia.org/wikipedia/commons/5/50/Bodiam-castle-10My8-1197.jpg",},{img: "https:upload.wikimedia.org/wikipedia/commons/4/4d/Balmoral_Castle.jpg",}];
var x = images;
var element = document.getElementById("container");
element.innerHtml = x;
next();
function next(){
element.innerHTML = x;
};

推荐答案

 var images  = [{img: "https://upload.wikimedia.org/wikipedia/commons/5/50/Bodiam-castle-10My8-1197.jpg"},{img: "https://upload.wikimedia.org/wikipedia/commons/4/4d/Balmoral_Castle.jpg"}];
var element = document.getElementById("container");
function next(direction){
  var index= element.dataset.index;
  if(direction=="right"){index++;}else{index--}
  if(index>images.length-1){index=0;}
  if(index<0){index=images.length-1;}
  element.dataset.index=index;
  element.style.backgroundImage  ="url('"+ images[index].img +"')";
};
