Calling Another A4j:jsfunction In An A4j:jsfunction Oncomplete Event

I define some java script function which will call the back-end functions using a4j:jsFunction.For example :

Solution 1:

jsf page:

<a4j:commandButtononcomplete="switchTab(1);"action="#{backBean.actionSwitchTab4}"value="#{res['button_forward']}c"styleClass="button" /><a4j:jsFunctionid="testFunc"name="switchTab"action="#{backBean.actionSwitchTab}"oncomplete="switchTab2(6);"><a4j:actionparamname="tabIndex"assignTo="#{backBean.tabIndexTl}" /></a4j:jsFunction><a4j:jsFunctionid="testFunc2"name="switchTab2"action="#{backBean.actionSwitchTab2}"oncomplete="showConfirmPrompt();"><a4j:actionparamname="tabIndex"assignTo="#{backBean.tabIndexTi}" /></a4j:jsFunction><a4j:jsFunctionid="testFunc3"name="switchTab3"action="#{backBean.actionSwitchTab3}"oncomplete="alert('this is the end');"><a4j:actionparamname="tabIndex"assignTo="#{backBean.tabIndexTs}"/></a4j:jsFunction><scriptlanguage="javascript"type="text/javascript"><!--
   function showConfirmPrompt() {
       if(confirm('Activate other a4j:jsFunction function')) {
           switchTab3('test');
           return true;
       }
       return false;
   }
   //--></script>

backbean(java):

private Integer tabIndexTi; // + GETTER, SETTERprivate String tabIndexTs;  // + GETTER, SETTERprivate Long tabIndexTl;    // + GETTER, SETTERpublic Object actionSwitchTab() {   
   System.out.println("  >>>>> actionSwitchTab start; tabIndexTl: " + tabIndexTl);   
   try {    
     Thread.sleep(2000);   
   } catch (InterruptedException ex) {    
     ex.printStackTrace();   
   }   
   System.out.println("  >>>>> actionSwitchTab end");   
   returnnull;  
  }

  public Object actionSwitchTab2() {   
   System.out.println("  >>>>> actionSwitchTab2 start; tabIndexTi: " + tabIndexTi);   
   try {    
     Thread.sleep(500);   
   } catch (InterruptedException ex) {    
     ex.printStackTrace();   
   }   
   System.out.println("  >>>>> actionSwitchTab2 end");   
   returnnull; 
  }

  public Object actionSwitchTab3() {   
    System.out.println("  >>>>> actionSwitchTab3 start; tabIndexTs: " + tabIndexTs);   
    try {    
      Thread.sleep(3000);   
    } catch (InterruptedException ex) {    
      ex.printStackTrace();   
    }   
    System.out.println("  >>>>> actionSwitchTab3 end");   
    returnnull; 
  }

  public Object actionSwitchTab4() {   
    System.out.println("  >>>>> actionSwitchTab4");   
    returnnull;  
  }
