Question

我尝试THIS模态，当我试图展示它时，它只是闪烁，因为它令人耳目一新.. 我正在用它来运行它：

<a href='index.php?id=".$id."' onclick='showDiag();'>

我根据表格中项目的选择更改 $ id

我编辑了一点JS：

// Get the modal
var modal = document.getElementById('myModal');

// Get the <span> element that closes the modal
var span = document.getElementsByClassName("close")[0];

// When the user clicks the button, open the modal
function showDiag() {
modal.style.display = "block";
}

// When the user clicks on <span> (x), close the modal
span.onload = function() {
modal.style.display = "none";
}

// When the user clicks anywhere outside of the modal, close it
window.onclick = function(event) {
if (event.target == modal) {
    modal.style.display = "none";
}
}

后来我通过

获取模态内容的值

<h2><?php echo "#".$_GET['id']; ?></h2>
etc...

我的问题是：我如何更改“？id = xx”以便javascript工作，只需点击一下即可动态更改内容？

非常感谢您的回答！

Answer 1

嗯，你有两个选择让模态工作。

将您的$command = '"/usr/local/bin/ffmpeg" -i值替换为href。
保持href="#openmodal"值不变，并在href方法中添加此行showDiag()同时将return false;值更改为＆＃34; {{1} }＆＃34;

对于选项一，它很简单，只需替换onclick值即可。对于选项二，下面是工作示例。

＆＃13;

return showDiag();

＆＃13;

href

＆＃13;

// Get the modal
var modal = document.getElementById('myModal');

// Get the button that opens the modal
var btn = document.getElementById("myBtn");

// Get the <span> element that closes the modal
var span = document.getElementsByClassName("close")[0];

// When the user clicks the button, open the modal
function showDiag() {
  modal.style.display = "block";
  return false;
}

// When the user clicks on <span> (x), close the modal
span.onclick = function() {
  modal.style.display = "none";
}

// When the user clicks anywhere outside of the modal, close it
window.onclick = function(event) {
  if (event.target == modal) {
    modal.style.display = "none";
  }
}

＆＃13;

如果您想获取某些其他用途的href值，可以将标记更改为：

/* 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 {
  position: relative;
  background-color: #fefefe;
  margin: auto;
  padding: 0;
  border: 1px solid #888;
  width: 80%;
  box-shadow: 0 4px 8px 0 rgba(0, 0, 0, 0.2), 0 6px 20px 0 rgba(0, 0, 0, 0.19);
  -webkit-animation-name: animatetop;
  -webkit-animation-duration: 0.4s;
  animation-name: animatetop;
  animation-duration: 0.4s
}
/* Add Animation */

@-webkit-keyframes animatetop {
  from {
    top: -300px;
    opacity: 0
  }
  to {
    top: 0;
    opacity: 1
  }
}
@keyframes animatetop {
  from {
    top: -300px;
    opacity: 0
  }
  to {
    top: 0;
    opacity: 1
  }
}
/* The Close Button */

.close {
  color: white;
  float: right;
  font-size: 28px;
  font-weight: bold;
}
.close:hover,
.close:focus {
  color: #000;
  text-decoration: none;
  cursor: pointer;
}
.modal-header {
  padding: 2px 16px;
  background-color: #5cb85c;
  color: white;
}
.modal-body {
  padding: 2px 16px;
}
.modal-footer {
  padding: 2px 16px;
  background-color: #5cb85c;
  color: white;
}

然后，在showDiag函数中，您可以获取href值并根据需要使用它。

<a href='index.php?id=something' onclick='return showDiag();'>Click here</a>
<!-- The Modal -->
<div id="myModal" class="modal">

  <!-- Modal content -->
  <div class="modal-content">
    <div class="modal-header">
      <span class="close">×</span>
      <h2>Modal Header</h2>
    </div>
    <div class="modal-body">
      <p>Some text in the Modal Body</p>
      <p>Some other text...</p>
    </div>
    <div class="modal-footer">
      <h3>Modal Footer</h3>
    </div>
  </div>

</div>

当我更改href时，Javascript将无法工作
