模态对话框 – Bootstrap Modal Focus无法正常工作

前端之家收集整理的这篇文章主要介绍了模态对话框 – Bootstrap Modal Focus无法正常工作前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。
@H_502_1@在制作网络时,我没有把注意力集中在Bootstrap Modal的“输入”中,我尝试了一切并且没有工作,模态出现但是输入没有得到焦点.我用一个简单的模态做了一个“test.PHP”,也没用.这是“test.PHP

        <h4 class="modal-title">Modal title</h4>
      </div>
      <div class="modal-body">
        <input name="referencia" id="referencia" type="text" class="form-control text-uppercase" placeholder="Descripci&oacute;n">
      </div>
      <div class="modal-footer">
        <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
        <button type="button" class="btn btn-primary">Save changes</button>
      </div>
    </div><!-- /.modal-content -->
  </div><!-- /.modal-dialog -->
</div><!-- /.modal -->
</body>

如果我在我的服务器上尝试此代码它不起作用,在unelink.es服务器也不工作,但如果我把相同的代码放在“小提琴”,工作正常.

什么是错的?如果我需要别的东西……或者在服务器上安装一些东西.

P.D.对不起我的英语不好.

解决方法

试试这个(自动对焦添加到您的链接):
<input name="referencia" id="referencia" type="text" class="form-control text-uppercase" placeholder="Descripci&oacute;n" autofocus>

或试试这个:

$('#myModal').on('shown.bs.modal',function () {
    $('#myInput').focus();
})

或这个:

// Every time a modal is shown,if it has an autofocus element,focus on it.
$('.modal').on('shown.bs.modal',function() {
  $(this).find('[autofocus]').focus();
});
