<button type="button" class="btn btn-info btn-md" id="myBtn3">Static 
Modal</button>

<!-- Modal -->
<div class="modal fade" id="myModal3" role="dialog">
<div class="modal-dialog">
  <!-- Modal content-->
  <div class="modal-content">
    <div class="modal-header">
      <button type="button" class="close" data-dismiss="modal">×</button>
      <h4 class="modal-title">Static Backdrop</h4>
    </div>
    <div class="modal-body">
      <p>You cannot click outside of this modal to close it.</p>
    </div>
    <div class="modal-footer">
      <button type="button" class="btn btn-default" data-
      dismiss="modal">Close</button>
    </div>
   </div>
  </div>
</div>
   <script>
    $("#myBtn3").click(function(){
     $("#myModal3").modal({backdrop: "static"});
    });
   });
  </script>

我发现最好的是把这个代码添加到链接中

<!-- Link -->
<a href="#mdl" role="button"  data-backdrop="static" data-keyboard="false" data-toggle="modal" id_team="" ></a>
<-- Div -->
<div id="mdl" class="modal hide fade" tabindex="-1" role="dialog" data-keyboard="false" data-backdrop="static"></div>

根据bootstrap 5更新的语法如下。 参考链接

<div class="modal fade" data-bs-backdrop="static" data-bs-keyboard="false" >

在引导5中属性名已经改变。你可以使用以下方法:

data-bs-backdrop="static" data-bs-keyboard="false"

我相信您想要将背景值设置为静态。如果您想避免在使用Esc键时关闭窗口，则必须设置另一个值。

例子:

<a data-controls-modal="your_div_id"
   data-backdrop="static"
   data-keyboard="false"
   href="#">

如果你使用JavaScript:

$('#myModal').modal({
  backdrop: 'static',
  keyboard: false
});

是的，你可以这样做:

<div id="myModal"  tabindex="-1" role="dialog"
     aria-labelledby="myModalLabel"
     aria-hidden="true"
     data-backdrop="static"  data-keyboard="false">
