我也遇到过类似的情况，经过一番研究，我找到了一个解决方案。虽然我不擅长JS，但我还是设法写下了一个小查询。

<div class="ingredient-item" data-toggle="modal" data-target="#myModal">test1 <p>trerefefef</p></div>
<div class="ingredient-item" data-toggle="modal" data-target="#myModal">tst2 <p>Lorem IpsumLorem IpsumLorem IpsumLorem IpsumLorem IpsumLorem IpsumLorem IpsumLorem IpsumLorem IpsumLorem IpsumLorem IpsumLorem IpsumLorem IpsumLorem IpsumLorem IpsumLorem IpsumLorem IpsumLorem IpsumLorem IpsumLorem IpsumLorem IpsumLorem IpsumLorem IpsumLorem IpsumLorem IpsumLorem IpsumLorem IpsumLorem IpsumLorem IpsumLorem IpsumLorem IpsumLorem IpsumLorem IpsumLorem IpsumLorem IpsumLorem IpsumLorem IpsumLorem IpsumLorem IpsumLorem IpsumLorem IpsumLorem IpsumLorem IpsumLorem Ipsum</p></div>
<div class="ingredient-item" data-toggle="modal" data-target="#myModal">test3 <p>afsasfafafsa</p></div>

<!-- Modal -->
<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
  <div class="modal-dialog">
    <div class="modal-content">
      <div class="modal-header">
        <button type="button" class="close" data-dismiss="modal" aria-hidden="true">&times;</button>
        <h4 class="modal-title" id="myModalLabel">Modal title</h4>
      </div>
      <div class="modal-body">
        ...
      </div>
      <div class="modal-footer">
        <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
        <button type="button" class="btn btn-primary">Save changes</button>
      </div>
    </div>
  </div>
</div>





$('.ingredient-item').on('click', function(e){

   e.preventDefault();

    var content = $(this).find('p').text();

    $('.modal-body').html(content);

});

这段代码非常适合用于引导4。其他代码中的问题是如何选择模态背景。这将是更好的，如果你使用jQuery的下一个选择在实际的模态已经显示。

(文档)。(“show.bs美元。模态”、“。Modal '， function () { var zIndex = 1040 + (10 * $('.modal').length); Var模型= $(this); model.css (z - index, zIndex); 模型。attr (data-z-index, zIndex); })； (文档)。(“shown.bs美元。模态”、“。Modal '， function () { Var模型= $(this); var zIndex = model.attr('data-z-index'); model.next('.modal- background .show').css('z-index'， zIndex - 1); })；

使用CSS进行Z-index和模态背景校正

.modal.fade {
  z-index: 10000000 !important;
  background: rgba(0, 0, 0, 0.5);
}
.modal-backdrop.fade {
  opacity: 0;
}

当解决堆叠模态滚动主页时，当一个关闭时，我发现Bootstrap的新版本(至少自3.0.3版本以来)不需要任何额外的代码来堆叠模态。

您可以向页面添加多个模态(当然有不同的ID)。当打开多个模态时发现的唯一问题是关闭一个模态时删除了体选择器的模态打开类。

你可以使用下面的Javascript代码来重新添加modal-open:

$('.modal').on('hidden.bs.modal', function (e) {
    if($('.modal').hasClass('in')) {
    $('body').addClass('modal-open');
    }    
});

在不需要背景效果的情况下，你可以设置data- background ="false"。

3.1.1版本。固定固定模式背景覆盖模式的滚动条，但上述解决方案似乎也适用于早期版本。

更新日期:2019年1月22日，13.41 我通过jhay优化了解决方案，它还支持关闭和打开相同或不同的对话框，例如，从一个细节数据向前或向后跨步到另一个细节数据。

(function ($, window) {

var MultiModal = function (element) {

    // show function to complete, after which the modal backdrop will have been created

    // we only want one backdrop; hide any extras
    setTimeout(function () {

        that.modalIndex++;

        if (that.modalIndex >= MultiModal.MAX_INDEX) {

我创建了一个Bootstrap插件，它包含了这里发布的很多想法。

它还解决了连续情态动词导致背景变得越来越暗的问题。这确保在任何给定的时间只有一个背景可见:

if(modalIndex > 0)
    $('.modal-backdrop').not(':first').addClass('hidden');

可见背景的z指数在show.bs.modal和hidden.bs.modal事件中都被更新:

$('.modal-backdrop:first').css('z-index', MultiModal.BASE_ZINDEX + (modalIndex * 20));
