<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>

把这两项加起来

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

现在看起来是这样的

<div class="modal fade bs-example-modal-sm" id="myModal" data-backdrop="static" data-keyboard="false" tabindex="-1" role="dialog" aria-labelledby="mySmallModalLabel" aria-hidden="true">

它将禁用逃避按钮，也点击任何地方和隐藏。

覆盖Dialog的Bootstrap ' hide '事件并停止其默认行为(以释放对话框)。

请参阅下面的代码片段:

   $('#yourDialogID').on('hide.bs.modal', function(e) {

       e.preventDefault();
   });

它在我们的例子中工作得很好。

如果你想有条件地禁用背景单击关闭功能。您可以使用下面的行在运行时将背景选项设置为静态。

引导v3.xx

jQuery('#MyModal').data('bs.modal').options.backdrop = 'static';

引导v2.xx

jQuery('#MyModal').data('modal').options.backdrop = 'static';

这将防止已经实例化的模型将背景选项设置为false(默认行为)关闭。

$(document).ready(function(e){

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

});

" background:'static'"将阻止关闭模式时，点击它之外; "keyboard: false"指定模式可以由escape键关闭(Esc) "show: false"将在页面加载完成时隐藏模式
