对bootstrap中confirm alert进行封装

<!-- system modal start -->

      <div class="modal-dialog modal-sm">
        <div class="modal-content">
          <div class="modal-header">
            <button type="button" class="close" data-dismiss="modal"><span aria-hidden="true">×</span><span class="sr-only">Close</span></button>
            <h5 class="modal-title"><i class="fa fa-exclamation-circle"></i> [Title]</h5>
          </div>
          <div class="modal-body small">
            <p>[Message]</p>
          </div>
          <div class="modal-footer" >
            <button type="button" class="btn btn-primary ok" data-dismiss="modal">[BtnOk]</button>
