flask - WTForm Submit 上的引导模式关闭 - 不显示错误

问题描述

在为我的烧瓶项目构建 HTML 代码时，即使提交时出现错误，我的模式也会在提交时关闭。如果有错误，我找不到保持模式显示的方法。

我尝试添加一些 JavaScript，但我不断收到错误，然后提交按钮根本不起作用。另外由于某种原因 $.path jQuery 命令不起作用（我认为这可能是因为我在本地服务器上？）

任何帮助深表感谢。

          </form>
        </div>
      </div>
    </div>
  </div>

我尝试使用但由于错误（Uncaught TypeError: $.post is not a function - 尽管我有 jQuery）而无法工作的 JavaScript 是：

$('#submit').click(function(event) {
  event.preventDefault();
  var url = "{{ url_for('training.completed_training') }}";
  $.post(url, data=$('#modForm').serialize(), function(data) {
    if (data.status == 'ok') {
      $('#myModal').modal('hide');
      location.reload();
    }
    else {
      $('#myModal .modal-content').html(data);
    }
})
});
