Question

我不是javascript，但我真的想在我的索引页面上随机化图片，所以想知道我能用我当前的javascript添加图片链接到每张图片吗？

< img id = "reklame" / >
  < script >
  function getRandomImage() {
    var images = ['bilder/reklame.jpg', 'bilder/reklame1.jpg', 'bilder/reklame2.jpg', 'bilder/reklame3.jpg'];
    var image = images[Math.floor(Math.random() * images.length)];

    return image;
  }

function displayRandomImage() {
  var htmlImage = document.getElementById("reklame");
  htmlImage.src = getRandomImage();
}
displayRandomImage(); < /script>

Answer 1

您可以使用setInterval功能

执行此操作

//First call
displayRandomImage();
var loop = setInterval(function() {
    //Call each 5 seconds
    displayRandomImage()
}, 5000);

希望这会奏效：

<html>
<head></head>
<body>
<div id = "reklame">
<img  / >
</div>
  <script type="text/javascript">
  function getRandomImage() {
    var images = ['bilder/reklame.jpg', 'bilder/reklame1.jpg', 'bilder/reklame2.jpg', 'bilder/reklame3.jpg'];
    var image = images[Math.floor(Math.random() * images.length)];

    return image;
  }

function displayRandomImage() {
  var imgDiv = document.getElementById("reklame");
  var image = imgDiv.getElementsByTagName('img')[0];
    image.src = getRandomImage();
  var a=document.createElement('a');
     a.href=getRandomImage();
     a.appendChild(image);
    imgDiv.appendChild(a);
} 

window.setInterval(function(){
      displayRandomImage();
}, 5000);
</script>
</body>
</html>

Answer 3

也许是这样的？

<a id="reklame-link" href="#";>
<img id = "reklame" />

function displayRandomImage() {
var htmlImage = document.getElementById("reklame");
var htmlLink = document.getElementById("reklame-link");
var randomImage = getRandomImage();
htmlImage.src = randomImage;
htmlLink.href = randomImage; 
console.log(getRandomImage()); 
}

在setInterval()

中调用displayRandomImage（）

window.setInterval(function(){
      displayRandomImage();
}, 5000);

  return image;
}

function displayRandomImage() {
  var htmlImage = document.getElementById("reklame");
  var link = document.getElementById("myuA");
  var imageObj = getRandomImage();
  htmlImage.src = imageObj.image;
  link.href  = imageObj.url;
}
displayRandomImage();
window.setInterval(function() {
  displayRandomImage();
}, 5000);
