javascript - PHP中的模态与php include

我正在尝试在PHP中使用包含功能的模式，但我猜header.php文件有错误。

这是模态的代码：

<!DOCTYPE html>
<html>
<head>
    <title></title>
    <?php include 'header.php'; ?>
</head>
<body>
<button id="myBtn">Open Modal</button>
<div id="myModal" class="modal">
  <div class="modal-content">
    <span class="close">x</span>
    <p>Some text in the Modal..</p>
  </div>

</div>
</body>
</html>

这是header.php文件中的内容：

<!-- Latest compiled and minified CSS -->
<link rel="stylesheet" href="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css">

<!-- jQuery library -->
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.2/jquery.min.js"></script>

<!-- Latest compiled JavaScript -->
<script src="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/js/bootstrap.min.js"></script>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
<link rel="stylesheet" type="text/css" href="/css/style.css" media="screen" />
<script type="text/javascript" src="file.js"></script>

编辑：

错误是css文件和js文件无法处理。
但是当我这样做时，它正在工作：

<!DOCTYPE html>
<html>
<head>
    <title></title>
<style type="text/css">
    /* The Modal (background) */
.modal {
    display: none; /* Hidden by default */
    position: fixed; /* Stay in place */
    z-index: 1; /* Sit on top */
    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/Box */
.modal-content {
    background-color: #fefefe;
    margin: 15% auto; /* 15% from the top and centered */
    padding: 20px;
    border: 1px solid #888;
    width: 80%; /* Could be more or less, depending on screen size */
}

/* The Close Button */
.close {
    color: #aaa;
    float: right;
    font-size: 28px;
    font-weight: bold;
}

.close:hover,
.close:focus {
    color: black;
    text-decoration: none;
    cursor: pointer;
}
</style>
</head>
<body>
<button id="myBtn">Open Modal</button>
<div id="myModal" class="modal">
  <div class="modal-content">
    <span class="close">x</span>
    <p>Some text in the Modal..</p>
  </div>

</div>
</body>
</html>
<script type="text/javascript">
// 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 on the button, open the modal
btn.onclick = function() {
    modal.style.display = "block";
}

// 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";
    }
}

</script>

最佳答案

您根本没有提供太多代码……但是，一针见血，您的模态将不会打开，因为您尚未在<button>上指定任何触发器。更改为：

<button id="myBtn" data-toggle="modal" data-target="#myModal">Open Modal</button>

最好阅读Bootstrap Modals来了解如何触发它们。
