用onClick随机图像

时间：2017-07-12 02:43:12

标签： javascript jquery html css

点击我网站上的“门”时，我希望在门框内显示6张随机图像中的一张。我已经将一个随机函数放在一个数组中，但是在将这些图像装入门框时遇到了麻烦。我在CSS中创建了适合图像的类，但在阅读了其他一些文章后，听起来我不能在javascript数组中调用css类？

非常感谢任何帮助!!

这是我的代码：https://codepen.io/tacodestroyer/pen/yXGMBv

这是我的代码：

HTML：

<script src="https://s.codepen.io/assets/libs/prefixfree.min.js"></script>
<script src="https://code.jquery.com/jquery-latest.js"></script>
<p class="alert">click on the door and try to click on more than one door</p>
<div class="perspective" onclick="openDoor(this); randomImg1()">
  <div id = "image" class="image"></div>
  <div class="thumb">
  </div>
</div>

<div class="perspective" onclick="openDoor(this)">
  <div class="image"></div>
  <div class="thumb">
  </div>
</div>
<div class="perspective" onclick="openDoor(this)">
  <div class="image"></div>
  <div class="thumb">
  </div>
</div>
<div class="perspective" onclick="openDoor(this)">
  <div class="image"></div>
  <div class="thumb">
  </div>
</div>

JS：

function openDoor(field) {
  var y = $(field).find(".thumb");
  var x = y.attr("class");
  if (y.hasClass("thumbOpened")) {
    y.removeClass("thumbOpened");
  } else {
    $(".thumb").removeClass("thumbOpened");
    y.addClass("thumbOpened");
  }
}

function randomImg1() {
  var myImage1 = new Array();
  myImage1[0] = ".image1";
  myImage1[1] = ".image2";
  myImage1[2] = ".image3";
  var random = Math.floor(Math.random() * myImage1.length);
  document.getElementById(".image").innerHTML =
    "<img src='" + myImage1[random] + "' alt='image'></img>";
}

你可以这样做。这取决于您在codepen中的内容。

function randomImg1() {
  var myImage1 = new Array();
  myImage1[0] = "https://68.media.tumblr.com/9768ea8b71fd67b7a90e7384c7756910/tumblr_inline_n1rtjwlsZb1so4q1u.jpg";
  myImage1[1] = "https://www.doyouyoga.com/wp-content/uploads/2017/01/dog-meme-10.jpg";
  myImage1[2] = "http://imworld.aufeminin.com/story/20140423/cat-meme-218141_w650.jpg";

  var classes = ['class1', 'class2', 'class3'];

  var random = Math.floor(Math.random() * myImage1.length);
  document.getElementById("image").attributes;
  document.getElementById("image").innerHTML =
    "<img src='" + myImage1[random] + "' class='" + classes[random] + "' alt='image'></img>" ;
}

class1将匹配您的第一张图片，class2您的第二张图片，依此类推。使用classes[random]将确保它们匹配，无论随机数是什么。
