PrimeFaces在“取消"按钮上禁用验证 [英] PrimeFaces disable validation on cancel button

问题描述

在一种形式中，我有一些带有两个commandButton的inputText，一个用于接受，一个用于取消.如何仅对取消按钮禁用验证?

In a form I have some inputText with two commandButton, one for accept and one for cancel. How can disable validation only for cancel button?

<h:form id="detailsForm">
  <p:inputText id="editUsername" value="#{userController.editUser.usrUsername}" />
  <p:inputText id="editFirstName" value="#{userController.editUser.usrFirstName}" />
  <p:inputText id="editLastName" value="#{userController.editUser.usrLastName}" />
  <p:commandButton value="Accept" update=":detailsForm" actionListener="#{userController.onDetailsEditAccept}" />
  <p:commandButton value="Cancel" update=":detailsForm" actionListener="#{userController.onDetailsEditCancel}" />
</h:form>

我已经尝试在字段上插入required="false"，但没有成功. 我也尝试在字段上插入<f:validateBean disabled="true" />，但没有成功.

I already tried to insert required="false" on fields but it didn't worked. I tried also to insert <f:validateBean disabled="true" /> on fields and it didn't worked.

推荐答案

在取消commandButton中使用属性immediate="true".通过跳过应用请求值，过程验证和更新模型值阶段，这将跳过表单的整个处理过程.

Use the attribute immediate="true" in your cancel commandButton. This will skip the entire processing of the form, tough, by skipping the Apply Request Values, Process Validations and Update Model Values phases.

<p:commandButton value="Cancel" update=":detailsForm" actionListener="#{userController.onDetailsEditCancel}" immediate="true"/>
