我正在尝试从第一个给定的输入动态更新第二个表单字段.我正在使用flatUI和bootstrap css文件。但是我无法像引导或平面UI那样更改生成的文本字段类型，它显示了一个基本的文本字段！好心有人帮我解决这个问题。谢谢 

    <!-- jQuery (necessary for Flat UI's JavaScript plugins) -->
    <script src="../dist/js/vendor/jquery.min.js"></script>
    <script src="../dist/js/vendor/video.js"></script>
    <!-- Include all compiled plugins (below), or include individual files as needed -->
    <script src="../dist/js/flat-ui-pro.js">
    <script>
    $(".contentContainer").css("min-height", $(window).height());
    </script>
  </body>
</html>

由于您已经在代码中包含 jQuery，因此您可以使用预定义的 CSS 类附加新字段，如下所示：

$('.container').append('<input class="form-control" type="text" placeholder="something"/>');

jQuery很容易调试，然后是vanilla javascript。

希望这可能会有所帮助！
