跳过验证阶段

Question

我有一个表格，我正在输入一些细节，所有的细节都是重要和必要的。我使用required=true来确保它不会遗漏重要信息，但是当我点击提交按钮时，它会跳过验证阶段。

我该怎么办?

Answer 1

问题是您使用了immediate="true"属性。

Answer 2

"immediate "指定侦听器在此之前触发执行验证或从文档中填充bean，但我在这里没有看到任何动作侦听器!当你使用required，这是正确的，你的代码完全工作时，我把它放在一个但没有requiredMessage显示，我也没有看到任何影响到ajax语句，我删除了它，没有任何改变，你可以把requiredMessage在一个bean字符串为其他输出文本和清除它编程使用ajax动作，所以试着把每个在一个表单，:

 <h:form>
    <p:inputText
   value="#{Offline_Payment.bankcode}" required="true"
                    requiredMessage="Please Enter The Required Details">
                    <p:ajax process="@this" immediate="true"></p:ajax>
                </p:inputText>
</h:form>

好运。
