如何在需要时跳过对 JSF 2 中某些字段的验证 [英] How to skip validation on certain fields in JSF 2 when required

问题描述

我有两个 p:dialog.每一个都包含一些标记为必需的输入字段.一次只显示一个对话框，但是当我提交任何对话框时，JSF 还会验证未显示的对话框的输入字段.对于未显示的对话框，跳过 JSF 2 中的验证的最佳方法是什么.一种方法可能是我设置了 required="condation".但不知道这种情况可能是什么，它是否会起作用.

I have two p:dialog. Each one contains some input fields which are marked as required. Only one dialog is shown at a time but when I submit on any of the dialog, JSF also validates the input fields of the dialog which is not shown. What is the best approach to skip the validations in JSF 2 for the dialog which is not shown. One approach could be that I set the required="condation". But dont know what that condition could be and is it goin to work.

每个对话框最初都是隐藏的.每个都有自己的按钮来显示.当一个处于活动状态并且我单击保存按钮时，即使必填字段具有值，也会出现验证错误.验证错误来自非活动对话框面板.也许它可以让我对我正在尝试做的事情有所了解.

Each dialog is initially hidden. Each one has its own button to show. When one is active and I click the save button there is a validation error even when the required field has values. The validation error comes from the inactive dialog panel. May be it give some idea what i am trying to do.

<p:dialog header="Edit Group" widgetVar="dialog_groupEdit" resizable="false"  
          width="300" showEffect="bounce" hideEffect="explode" modal="true" position="center">

推荐答案

一种方法可能是我设置 required="condation".

这将是笨拙的.只需将每个单独的表单放在自己单独的 组件中，或者使用 的 process 属性> 确定您要处理的区域.

This is going to be clumsy. Just put each individual form in its own separate <h:form> component, or use the process attribute of the <p:commandButton> to identify the region you'd like to process.

<p:commandButton process="panel_groupEdit" ... />

...

<p:commandButton process="panel_groupCreate" ... />

有一个上帝"形式在任何方面都是一种糟糕的做法.

Having a "God" form is in any way a poor practice.
