加载克隆的模态（引导程序）

Question

是否可以使用引导程序加载新克隆的模态？

我需要加载许多不同的模态，但下面是一个尝试仅加载一个新模态的示例。

我看到有关在模态中加载克隆元素的问题，但不是完全克隆的模态。

这是一个问题：http://jsfiddle.net/hde13s2t/6/

步骤：

1. 用户点击“克隆”来克隆模态

2. Javascript 克隆模态并将适当的标签重命名为“克隆”（按钮和模态标签）

3. 用户点击克隆的模态-->“Launch demo modal 2”

html 都正确加载，但新模式没有触发。

HTML：

<!-- Button trigger modal -->
<div id="launchmodal1">

  <button type="button" class="btn btn-primary" data-toggle="modal" id="examplemodalbutton1" data-target="#exampleModal1">
    Launch demo modal 1
  </button>

  <!-- Modal -->
  <div class="modal fade" id="exampleModal1" tabindex="-1" role="dialog" aria-labelledby="exampleModalLabel" aria-hidden="true">
    <div class="modal-dialog" role="document">
      <div class="modal-content">
        <div class="modal-header">
          <h5 class="modal-title" id="exampleModalLabel">Modal title</h5>
          <button type="button" class="close" data-dismiss="modal" aria-label="Close">
            <span aria-hidden="true">&times;</span>
          </button>
        </div>
        <div class="modal-body">
          ...
        </div>
        <div class="modal-footer">
          <button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button>
          <button type="button" class="btn btn-primary">Save changes</button>
        </div>
      </div>
    </div>
  </div>
 </div>
</div>
<button type="button" class="btn btn-secondary" id="clicktoclone">Clone</button>

Javascript：

$(document).on("click", "#clicktoclone", function() {
    var secondmodal = $("#launchmodal1").clone();

  // updating button id and data-target for modal 2
  secondmodal.find("#examplemodalbutton1").attr("id", "examplemodalbutton2").attr("data-target", "exampleModal2").html("Launch demo modal 2");

  // updating modal id for modal 2
  secondmodal.find("#exampleModal1").attr("id", "examplemodal2");

  secondmodal.appendTo('#launchmodal2');
});

jQuery.clone 不会为新的 DOM 元素克隆引导事件。因此，您必须在新模态附加到 DOM 树后设置模态调用：

$(document).on("click", "#clicktoclone", function() {
    var secondmodal = $("#launchmodal1").clone();

  // updating button id and data-target for modal 2
  secondmodal.find("#examplemodalbutton1").attr("id", "examplemodalbutton2").attr("data-target", "exampleModal2").html("Launch demo modal 2");

  // updating modal id for modal 2
  secondmodal.find("#exampleModal1").attr("id", "examplemodal2");

  secondmodal.appendTo('#launchmodal2');

  // set new click event to show the cloned modal
  $('#examplemodalbutton2').on('click', function() {
    $('#examplemodal2').modal();
  })
});

如果您有多个模态的克隆，您可以将全局单击事件侦听器绑定到所有模态按钮：

  $(document).on('click', '.btn', function() {
    var targetSelector = $(this).data('target');
    $(targetSelector).modal();
  })
