Materialize 从触发器获取数据信息

Question

有没有办法从触发按钮传输到模态 div 一些数据？

这是我的代码。

<button data-id="123" class="modal-trigger" href="#info-modal">OPEN 123</button>
<button data-id="456" class="modal-trigger" href="#info-modal">OPEN 456</button>
<div class="modal">
    <div class="modal-content">
        <h4>My Modal</h4>
        <p>this info arrives from the data-id attribute on the trigger.</p>
    </div>
    <div class="modal-footer">
        <a href="#!" class="modal-close waves-effect waves-red btn-flat">CLOSE</a>
    </div>
</div>
<script>
    jQuery( document ).ready(function($) {
        $(".modal").modal({
            onOpenStart: function(){
                // changes the p content inside .modal-content from the data-id triggered button.
            }
        });
    });
</script>

您可以将点击监听器添加到您的按钮，然后当按钮被点击时，您可以使用 this 引用从被点击的按钮中获取 data-id 属性的值，然后将该值放入模态使用 .html() 方法。

这是有效的 example 和您修改后的代码：

<button data-id="123" class="modal-trigger" href="#info-modal">OPEN 123</button>
<button data-id="456" class="modal-trigger" href="#info-modal">OPEN 456</button>
<link rel="stylesheet" href="https://netdna.bootstrapcdn.com/bootstrap/3.1.1/css/bootstrap.min.css">
<div class="modal" id="modal">
    <div class="modal-content">
        <h4>My Modal</h4>
        <p>this info arrives from the data-id attribute on the trigger.</p>
    </div>
    <div class="modal-footer">
        <a href="#!" class="modal-close waves-effect waves-red btn-flat">CLOSE</a>
    </div>
</div>

<script type="text/javascript">
    $( document ).ready(function($) {
    $(".modal-trigger").click(function(){
          var data_id = $(this).attr('data-id');
          $("#modal .modal-content p").html(data_id);
          $('#modal').modal('show');
    });
        
    });
</script>
