我想创建一个按钮来选择所有复选框,但我找不到一个适合我的例子。我使用的是素数面。
<p:selectManyCheckbox widgetVar="sex" id="sexta" value="#{solicitacaoAcompanhamentoMB.selectedHorariosSexta}" layout="pageDirection">
<f:selectItem itemLabel="12:00" itemValue="Sexta-12:00" />
<f:selectItem itemLabel="12:30" itemValue="Sexta-12:30" />
<f:selectItem itemLabel="13:00" itemValue="Sexta-13:00" />
<f:selectItem itemLabel="13:30" itemValue="Sexta-13:30" />
<f:selectItem itemLabel="14:00" itemValue="Sexta-14:00" />
<f:selectItem itemLabel="14:30" itemValue="Sexta-14:30" />
<f:selectItem itemLabel="15:00" itemValue="Sexta-15:00" />
<f:selectItem itemLabel="16:00" itemValue="Sexta-16:00" />
<f:selectItem itemLabel="16:30" itemValue="Sexta-16:30" />
<f:selectItem itemLabel="17:00" itemValue="Sexta-17:00" />
<f:selectItem itemLabel="17:30" itemValue="Sexta-17:30" />
<f:selectItem itemLabel="18:00" itemValue="Sexta-18:00" />
<f:selectItem itemLabel="18:30" itemValue="Sexta-18:30" />
<f:selectItem itemLabel="19:00" itemValue="Sexta-19:00" />
<f:selectItem itemLabel="19:30" itemValue="Sexta-19:30" />
<f:selectItem itemLabel="20:00" itemValue="Sexta-20:00" />
<f:selectItem itemLabel="20:30" itemValue="Sexta-20:30" />
<f:selectItem itemLabel="21:00" itemValue="Sexta-21:00" />
<f:selectItem itemLabel="21:30" itemValue="Sexta-21:30" />
<f:selectItem itemLabel="22:00" itemValue="Sexta-22:00" />
<f:selectItem itemLabel="22:30" itemValue="Sexta-22:30" />
</p:selectManyCheckbox>
您可以添加commandLink
<p:commandLink id="selectAll" update="sexta" actionListener="#{yourBean.selectAll}" process="@this,locations">
<h:outputText value="Select all" />
</p:commandLink>
Java中的方法(在您的Bean类中):
public void selectAll(ActionEvent actionEvent) {
selectedHorariosSexta.clear();
int startHour = 12;
for (int i = 0; i < 22; i++) {
if (i % 2 == 0) {
selectedHorariosSexta.add("Sexta-" + startHour + ":00");
}else {
selectedHorariosSexta.add("Sexta-" + startHour + ":30");
startHour++;
}
}
}
