Question

触发代码

<a href="/admin/user/edit/modal.html" class="btn btn-info" data-toggle="modal" data-target="#modal-login">编辑</a>
    <!-- Modal -->
    <div class="modal" id="modal-login" tabindex="-1" >
      <div class="modal-dialog" style="width:1100px">
        <div class="modal-content">
        </div>
      </div>
    </div>

modal.html页

        <div class="modal-header">
          <button type="button" class="close" data-dismiss="modal">×</button>
          <h4 class="modal-title" id="myModalLabel">编辑</h4>
        </div>
        <div class="modal-body">
        </div>
        <div class="modal-footer">
          <button type="button" class="btn btn-default" data-dismiss="modal">关闭</button>
          <button type="button" class="btn btn-primary">提交</button>
        </div>
