如何使图像充当按钮，并使其在单击时执行操作（启动关键帧事件，运行脚本）？

Question

我刚刚在学校开始编码，我们的老师太恐怖了。 我必须自学编码，因此，我来​​这里寻求帮助:)。 我已经使用一些简单的html和css创建了这个网站，现在我想要的是我在导航栏中用作按钮的图像，并在按下时执行一些很酷的操作，例如制作动画，或启动一个关键帧事件，在该事件中，我设置的一些关键帧将触发（例如闪烁的文本），甚至可能运行很酷的JavaScript。 这主要是为了表演，但与此同时，我在这里学习。 如果我的代码编写不正确，请随时对其进行纠正。 谢谢。

Answer 1

有几种方法可以这样做：

1. 像这样添加锚标签

   <a type="button" href="the url" id="myId">put the image element here</a>

2. 在JavaScript中为ID为的元素编写一个点击函数

   document.getElementById("myId").onclick=function() { /* some code here */ }

Answer 2

您可以在按钮内添加以下标签的图像按钮

<input type="image" src="http://somesite.com/somepath/someimage.png" />

要么

<button style="background: url(someimage.png)" ... />

Answer 3

如果您的图像尺寸合适，则可以将其设置为该特定“ a”标签的背景。

所以应该是这样的：

<li><a  class="funImage" href="" target="_blank"></a></li>

然后在CSS中，您可以执行以下操作：

.funImage{display: inline-block;
          background-image: url("bilde.png");
          height: /*Set height accordingly*/;
          width: /*Set width accordingly*/; 
         }

希望能奏效:)

Answer 4

您可以使用Jquery执行类似的操作。

<img src="yan.png" alt="image" id="image">

并在您的脚本中放置此代码

<script src="https://code.jquery.com/jquery-3.2.1.min.js"></script>
<script type="text/javascript>
    $(document).ready(function(){
        $('#image').click(function(){ 
        alert('image clicked');
      });
    });
</script>

坐在警报中，您可以做一些很酷的事情。
