最近，当按下“添加到购物车”按钮时，我被要求向WooCommerce产品页面添加一个模式。首先，我复制并修改了w3schools模式示例，并将其插入到子主题的单产品>添加到购物车> simple.php文件中。当我注释掉默认情况下隐藏模态的CSS行时，单击按钮会弹出模态，就像在示例中所做的那样。但是，当我离开该行时，当按下按钮时，模式将不会显示。我尝试使用不透明度代替显示属性，但没有取得有意义的不同结果。我对相当基本的HTML有一些经验，对PHP几乎没有经验，但我对正在发生的事情的最佳猜测是，这是某种形式的执行顺序问题。

以下是来自modal的演示代码

<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width, initial-scale=1">

</head>
<body>

<h2>Modal Example</h2>

<!-- Trigger/Open The Modal -->
<button id="myBtn">Open Modal</button>

<!-- The Modal -->
<div id="myModal" class="modal">

  <!-- Modal content -->
  <div class="modal-content">
    <span class="close">&times;</span>
    <p>Some text in the Modal..</p>
  </div>

</div>

<style>
body {font-family: Arial, Helvetica, sans-serif;}

/* 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;
}
</style>

<script>
// 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 
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>

</body>
</html>

下面是我的simple.php文件的相关部分：

defined( 'ABSPATH' ) || exit;

global $product;

if ( ! $product->is_purchasable() ) {
    return;
}

echo wc_get_stock_html( $product ); // WPCS: XSS ok.

if ( $product->is_in_stock() ) : ?>

    <?php do_action( 'woocommerce_before_add_to_cart_form' ); ?>



                                                    <!-- Add code for modal here -->
                        <!-- Some style stuff -->

<!-- The Modal -->
<div id="myModal" class="modal">

  <!-- Modal content -->
  <div class="modal-content">
    <span class="close">&times;</span>
    <p>SAMPLE TEXT HERE</p>
  </div>

</div>

<style>
body {font-family: Arial, Helvetica, sans-serif;}

/* The Modal (background) */
.modal {
    /*display: none; /* Hidden by default */
    position: fixed; /* Stay in place */
    z-index: 1; /* Sit on top */
    padding-top: 500px; /* 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: #ff0080;
    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;
}
</style>


    <form class="cart" action="<?php echo esc_url( apply_filters( 'woocommerce_add_to_cart_form_action', $product->get_permalink() ) ); ?>" method="post" enctype='multipart/form-data'>
        <?php do_action( 'woocommerce_before_add_to_cart_button' ); ?>

        <?php
         do_action( 'woocommerce_before_add_to_cart_quantity' );

         /*woocommerce_quantity_input( array(
            'min_value'   => apply_filters( 'woocommerce_quantity_input_min', $product->get_min_purchase_quantity(), $product ),
            'max_value'   => apply_filters( 'woocommerce_quantity_input_max', $product->get_max_purchase_quantity(), $product ),
            'input_value' => isset( $_POST['quantity'] ) ? wc_stock_amount( wp_unslash( $_POST['quantity'] ) ) : $product->get_min_purchase_quantity(), // WPCS: CSRF ok, input var ok.
        ) ); */

        do_action( 'woocommerce_after_add_to_cart_quantity' ); 
        ?>      

        <button type="submit" name="add-to-cart" value="<?php echo esc_attr( $product->get_id() ); ?>" class="single_add_to_cart_button button alt"><?php echo esc_html( $product->single_add_to_cart_text() ); ?></button>




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

// Get the button that opens the modal
var btn = document.getElementsByClassName("single_add_to_cart_button button alt");

// Get the <span> element that closes the modal
var span = document.getElementsByClassName("close")[0];
modal.style.display = "none";
// When the user clicks 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>



        <?php do_action( 'woocommerce_after_add_to_cart_button' ); ?>
    </form>

    <?php do_action( 'woocommerce_after_add_to_cart_form' ); ?>

<?php endif; ?>

我尝试过将HTML和CSS部分移到其他文件中，但这并没有解决问题。我通过互联网研究发现的大部分信息都表明，我默认设置了.modal {display: none;}，这就是这个例子已经在做的。知道为什么这不管用吗？

按钮被抓住了，模式正在准备做它的事情。然而，然后提交表单，浏览器就会完成它的工作--从页面导航。我修改了您的代码，所以现在它捕获--然后阻止--表单被提交。

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

// Get the form
var form = document.getElementById('myForm');

// Get the <span> element that closes the modal
var span = document.getElementById('myModalClose');


// When the user clicks the button, open the modal 
form.onsubmit = function() {
    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";
    }
}

body {font-family: Arial, Helvetica, sans-serif;}

/* The Modal (background) */
.modal {
    display: none; /* Hidden by default */
    position: fixed; /* Stay in place */
    z-index: 1; /* Sit on top */
    padding-top: 500px; /* 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: #ff0080;
    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;
}

<div id="myModal" class="modal">
	<div class="modal-content">
		<span id="myModalClose" class="close">&times;</span>
		<p>SAMPLE TEXT HERE</p>
	</div>
</div>

<form id="myForm" class="cart" action="#" method="post" enctype='multipart/form-data'>
