如何在质数中选择所有复选框

Question

I want to write a code where on selection of one checkbox all other checkboxes grouped under selectManycheckbox are also selected.

<p:selectManyCheckbox id="inputSelectManyCheckbox" value="#{valueList}"  
valueChangeListener="#{valueChangeMethod}" label="#{label}">
              <p:ajax listener="#{actionListener}" />
 </p:selectManyCheckbox>

Answer 1

Try this:

<p:selectBooleanCheckbox value="#{...}">
  <p:ajax event="change" 
          listener="yourBean.checkAll()" 
          update="inputSelectManyCheckbox" />
</p:selectBooleanCheckbox>

... and ...

@ManagedBean
@....Scoped
public class YourBean {
  public void checkAll(){
    for(Boolean b : this.getValueList()){
      b = true;
    }
  }
}

Please note: the value of a p:selectManyCheckbox is a list of only the selected items! I hope you can adapt my example to your code!
