递交表格时无邮寄要求

Question

下面是signup.html，当用户填充表单字段，然后按下按钮或按ENTER键，什么都不会发生，而Flask只显示在填充用户之前发出的获取页面的GET请求

没有发出POST请求，将action="{{url_for('UI.signup')}}"更改为action='/signup'不能解决问题。

我希望用这个html来表示签名页，但出于某种原因，它在填充数据后不会创建post请求。

type="button"创建一个不执行任何操作的按钮。它的存在完全是为了将JavaScript连接到。

去掉它(默认为type="submit")，单击该按钮时，该按钮将提交表单。
