添加不同的ID到2个不同的引导模式背景

Add different ID to 2 different Bootstrap modal-backdrop

我在一个页面上有2个模态，每个模态有不同的行为，如果页面大于指定的宽度，一个模态将转换为页面内容。为了实现这一点，我使用jQuery来隐藏其模态背景，但问题是，脚本也将隐藏具有正常行为的第二模态背景。如何为每个模态背景分配不同的ID ?

<button type="button" class="btn btn-primary btn-lg" data-toggle="modal" data-target="#myModal1">
  Launch modal with modal-backdrop id 1
</button>

<button type="button" class="btn btn-primary btn-lg" data-toggle="modal" data-target="#myModal2">
  Launch modal with modal-backdrop id 2
</button>


<!-- Modal1 modal-backdrop id 1-->
<div class="modal fade" id="myModal1" tabindex="-1" role="dialog" aria-labelledby="myModalLabel">
  <div class="modal-dialog" role="document">
    <div class="modal-content">
      <div class="modal-header">
        <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">&times;</span></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>
<!-- Modal2 modal-backdrop id 2-->
  <div class="modal fade" id="myModal2" tabindex="-1" role="dialog" aria-labelledby="myModalLabel">
    <div class="modal-dialog" role="document">
      <div class="modal-content">
        <div class="modal-header">
          <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">&times;</span></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>

您可以使用bootstrap modal的.on('show.bs.modal'事件来相应地更改您的背景，如下所示:

$("#myModal1,#myModal2").on('show.bs.modal', function (e) {
    var that=$(this);
    var id=that.attr('id'); //get the id of button which got clicked
    setTimeout(function(){
        $('.modal-backdrop').attr('data-id',id);
        //You can either assign it as data-* attribute or add it as class to backdrop like
        //$('.modal-backdrop').addClass(id);
    });
});

现在你可以使用这个来根据modal的行为进行修改。

这会解决你的问题。

<div class="modal fade" id="myModal2" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" data-keyboard="false" data-backdrop="static" >
