暂时禁用JSF验证 [英] Temporarily disable JSF validations

问题描述

A具有许多必需的输入和验证.几个命令按钮控制不同的输入.

A has many required inputs and validations. A couple of command buttons control different inputs.

我可以用<f:param>的值更改所需的着装.例如，当单击一个按钮时，它会设置一个值.无论是否需要输入，此值都会更改.像这样:

I can change required attibrute with the value of <f:param>. For instance when a button is clicked,it sets a value.This value changes if an input is required or not. Like this:

<p:commandButton>
        <f:param name="button1" value="1"></f:param>
        </p:commandButton>

        <h:inputText required="#{param['button1'] == 1}"></h:inputText>

这实际上有效.但是我还想添加一些限制，例如最大长度.我也想暂时更改此验证.

This actually works.However i also want to add some valitations like max length.I want to temporarily change this validation too.

我试图禁用valitadion，但是我没有用:

I tried to disable valitadion,but i did not work:

<f:validateLength  disabled="true" maximum="10"></f:validateLength>

推荐答案

您似乎已经在使用JSF2.x.因此，只需使用<f:ajax execute>或<p:commandButton process>来指定按下按钮时将要执行/处理的组件的客户端ID.所有未包含在其中的组件都将被忽略并且不进行转换/验证.

You seem to be using JSF 2.x already. So just use <f:ajax execute> or <p:commandButton process> to specify client IDs of components which are to be executed/processed when the button is pressed. All components which are not included in this will just be ignored and not converted/validated.

例如

<h:inputText id="input1" ... required="true" />
<h:inputText id="input2" ... required="true" />
<h:inputText id="input3" ... required="true" />
<h:inputText id="input4" ... required="true" />

<p:commandButton value="Submit inputs 1 and 2" process="input1 input2" ... />
<p:commandButton value="Submit inputs 3 and 4" process="input3 input4" ... />

如果使用<p:commandButton>，则默认为@form(即整个当前表格).

In case of <p:commandButton> it defaults to @form (i.e. the entire current form).
