<button class="btn btn-primary btn-lg" data-backdrop="static" data-keyboard="false" data-target="#myModal" data-toggle="modal">

也工作，data- background ="static"点击出来和data-keyboard="false"到Esc在你的div模式:

<div id="idModal" class="modal hide" data-backdrop="static" data-keyboard="false">

我使用这些属性，它可以工作，data-keyboard="false" data- background ="static"

只需在该模式中添加data- background ="static"和data-keyboard="false"属性即可。

Eg.

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

<div class="modal show">
  <div class="modal-dialog">
    <div class="modal-content">
      <div class="modal-header">     

    <h4 class="modal-title">Modal title</h4>
     </div>
     <div class="modal-body">
      <p>One fine body&hellip;</p>
  </div>

  </div><!-- /.modal-content -->
</div><!-- /.modal-dialog -->

我觉得这个密码本可以帮到你 防止模态关闭CSS和引导

<button class="btn btn-primary btn-lg" data-backdrop="static" data-keyboard="false" data-target="#myModal" data-toggle="modal">
