javascript - 图片未在弹出窗口中显示（CSS、HTML、Javascript）

问题描述

目前，我正在建立一个网站，但遇到了问题。我对 CSS、HTML、Javascript 的世界还很陌生，所以也许这对你们大多数人来说是没有道理的，但我面临以下问题。我想在弹出窗口中有一张图片，但是该图片没有显示（在片段中称为“ErrorImage”）。我检查了图像的文件路径是否正确，并且正确。请查看下面的片段。有什么帮助吗？

// When the user clicks on div, open the popup
function myFunction() {
  var popup = document.getElementById("myPopup");
  popup.classList.toggle("show");
}
/* Popup container - can be anything you want */
.popup {
  position: relative;
  display: inline-block;
  cursor: pointer;
  -webkit-user-select: none;
  -moz-user-select: none;
  -ms-user-select: none;
  user-select: none;
}

/* The actual popup */
.popup .popuptext {
  visibility: hidden;
  width: 500px;
  background-color: #555;
  color: #fff;
  text-align: center;
  border-radius: 6px;
  padding: 10px;
  position: absolute;
  z-index: 1;
  bottom: 60px;
  left: -50%;
  right: -50%;
  margin-left: -80px;
    opacity: 0.98;
    text-align: justify;
}

/* Toggle this class - hide and show the popup */
.popup .show {
  visibility: visible;
  -webkit-animation: fadeIn 1s;
  animation: fadeIn 1s;
}

/* Add animation (fade in the popup) */
@-webkit-keyframes fadeIn {
  from {opacity: 0;} 
  to {opacity: 1;}
}

@keyframes fadeIn {
  from {opacity: 0;}
  to {opacity:1 ;}
}   
<div class="popup" onclick="myFunction()">
    <a title="More about us">
        <img src="About.JPG" alt="About">
    </a>
    <span class="popuptext" id="myPopup"><img src="ErrorImage.JPG"<
        <p>Example text</p>
    </span>
</div>

解决方案

它正在显示，但你的左边是 -50%，这就是它离开屏幕的原因。我已经相应地对其进行了调整，以便它显示在屏幕上。希望这可以帮助。谢谢
