选择所有p：selectManyCheckbox

Question

我想创建一个按钮来选择所有复选框，但我找不到适用于我的一个示例。我正在使用primefaces。

 <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> 

Answer 1

您可以在Java中添加commandLink

<p:commandLink id="selectAll" update="sexta" actionListener="#{yourBean.selectAll}" process="@this,locations"> 
    <h:outputText value="Select all" /> 
</p:commandLink> 

和方法（在yourBean类）：

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++; 
     } 
    }  
}
