javascript - 如何使用 jquery .load 打开模态框

Question

嗨，我编写了一段代码，以便在单击图像后我可以打开模式。例如，如果我单击 pi 书封面的生命，它将打开一个显示有关它的信息的模式。但由于某种原因它不起作用，我不确定为什么。另请注意，pi 的生命周期只有一个唯一的 id，因为我首先只在一张图像上测试它。代码如下

$(document).ready(function() {
  var $modal = $("#myModal");
  $("#lifeofpi").click(function() {
    $modal.show();
  });
  $modal.find('.close').click(function() {
    $modal.hide();
  });
});

/* The Modal (background) */

.modal {
  display: none;
  /* Hidden by default */
  position: fixed;
  /* Stay in place */
  z-index: 1;
  /* Sit on top */
  padding-top: 100px;
  /* Location of the box */
  left: 0;
  top: 0;
  width: 100%;
  /* Full width */
  height: 100%;
  /* Full height */
  overflow: auto;
  /* Enable scroll if needed */
  background-color: rgb(0, 0, 0);
  /* Fallback color */
  background-color: rgba(0, 0, 0, 0.4);
  /* Black w/ opacity */
}


/* Modal Content */

.modal-content {
  background-color: #fefefe;
  margin: auto;
  padding: 20px;
  border: 1px solid #888;
  width: 80%;
}


/* The Close Button */

.close {
  color: #aaaaaa;
  float: right;
  font-size: 28px;
  font-weight: bold;
}

.close:hover,
.close:focus {
  color: #000;
  text-decoration: none;
  cursor: pointer;
}

.review-img {
  cursor: pointer;
}

您需要通过使用 show() 更改 css 属性 display: none 来使模式可见。

$(function(){
  var $modal = $("#myModal");
  $(".review-img").each(function() {
    var $image= $(this);
    $image.on("click", function() {
      var url = '/bookDetails/' + $image.data("bookid") + '.html';
      // Test:
      url = 'https://httpbin.org/html';
      $modal.find('.modal-content p').html('Loading...').load(url);
      $modal.show();
    });

  });
  $modal.find('.close').click(function() {
    $modal.hide();
  });
});

/* The Modal (background) */

.modal {
  display: none;
  /* Hidden by default */
  position: fixed;
  /* Stay in place */
  z-index: 1;
  /* Sit on top */
  padding-top: 100px;
  /* Location of the box */
  left: 0;
  top: 0;
  width: 100%;
  /* Full width */
  height: 100%;
  /* Full height */
  overflow: auto;
  /* Enable scroll if needed */
  background-color: rgb(0, 0, 0);
  /* Fallback color */
  background-color: rgba(0, 0, 0, 0.4);
  /* Black w/ opacity */
}


/* Modal Content */

.modal-content {
  background-color: #fefefe;
  margin: auto;
  padding: 20px;
  border: 1px solid #888;
  width: 80%;
}


/* The Close Button */

.close {
  color: #aaaaaa;
  float: right;
  font-size: 28px;
  font-weight: bold;
}

.close:hover,
.close:focus {
  color: #000;
  text-decoration: none;
  cursor: pointer;
}

.review-img {
  cursor: pointer;
  height: 100px;
}
