[英]Primefaces selectonemenu requiredmessage
I am creating a selectonemenu using Primefaces and JSF. 我正在使用Primefaces和JSF创建一个selectonemenu。 I want to appear a message saying "Choose one of the options".
我想出现一条消息,说“选择其中一个选项”。 How can I do that?
我怎样才能做到这一点?
This is the code: 这是代码:
<!--Gender-->
<p:selectOneMenu id="gender" value="#{users.gender}" required="true"
requiredMessage="Choose one of the options">
<f:selectItem itemLabel="Choose gender" itemValue="#{null}" />
<f:selectItem itemLabel="Male" itemValue="Male" />
<f:selectItem itemLabel="Female" itemValue="Female" />
</p:selectOneMenu>
Thanks 谢谢
adding below on the submit button will work fine as well. 在“提交”按钮上添加以下内容也可以正常工作。 ajax="false"
AJAX = “假”

As you requested, please find below block of codes that works fine for me ::
<h:form>
<p:panelGrid style="margin-top:5px;width:730px;">
<f:facet name="header">
<p:row >
<p:column colspan="20">Select Company</p:column>
</p:row>
</f:facet>
<p:row>
<p:column>
<p:selectOneMenu id="companyMenu" value="#{clientList.clientCode}"
style="width:550px;margin:5px;text-color:black" required="true"
requiredMessage="Please select a company !">
<f:selectItem itemLabel="Select a Company" noSelectionOption="true"
itemValue="#{null}" />
<f:selectItems value="#{clientList.clients.entrySet()}" var="entry"
itemValue="#{entry.key}" itemLabel="#{entry.value}" >
</f:selectItems>
</p:selectOneMenu>
</p:column>
<p:column>
<p:commandButton value="Submit" style="margin:5px;" action="#
{viewPayment.companyDetails(clientList.clientCode)}" ajax="false"/>
</p:column>
</p:row>
</p:panelGrid>
</h:form>
You can use : 您可以使用 :
if (users.getGender()==null) {
FacesContext.getCurrentInstance().addMessage(
null,
new FacesMessage(FacesMessage.SEVERITY_ERROR,
"Choose one of the options",
"Choose one of the options"));
}
SOLVED.I forgot to add the line <p:message for="gender" />
to the code. 已解决。我忘了在代码中添加
<p:message for="gender" />
行。 Thanks. 谢谢。
