bootstrap如何增加多个模态框以及解决各个模态框互不影响的问题

关键所在

第一个模态框的点击按钮的 data-target="#myModal"对应第一个模态框的id=“myModal”;所以一个页面上不同模态框的启动就在于此 ，只需要把第二个模态框的按钮的data-target改为data-target="#myModal_1";第二个模态框的id改为id=“myModal_1”;就可以分别打开两个不同的模态框。增加多个模态框道理也是如此。

第一个模态框

按钮
<button type="button" class="btn btn-primary btn-lg" data-toggle="modal" data-target="#myModal">
  Launch demo modal
</button>

模态框主体
<div class="modal fade" id="myModal" 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>
      </div>
      <div class="modal-body">
    模态框一号
      </div>
      <div class="modal-footer">
        <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
      </div>
    </div>
  </div>
</div>

第二个模态框
按钮
<button type="button" class="btn btn-primary btn-lg" data-toggle="modal" data-target="#myModal_1">
  Launch demo modal
</button>


模态框主体
<div class="modal fade" id="myModal_1" 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>
      </div>
      <div class="modal-body">
        模态框二号
      </div>
      <div class="modal-footer">
        <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
      </div>
    </div>
  </div>
</div>
