Question

我定义了一些java脚本函数，它将使用a4j调用后端函数：jsFunction。例如：

<a4j:jsFunction name="function1"  action="#{Bean1.action1}" oncomplete="function2();"/> 

<a4j:jsFunction name="function2"  action="#{Bean1.action2}" oncomplete="SomeJSFunc2();"/>

然后在a4j：commandButton中，我设置了onclick属性来调用我定义的函数：

<a4j:commandButton onclick="function1" oncomplete="SomeJSFunc3();">

单击a4j：commandButton时，运行＃{Bean1.action1}。＃{Bean1.action1}返回后，（a4j：jsFunction name =“function1”）的oncomplete事件无法调用“＃{Bean1.action2}”。如何解决这个问题？

jsf页面：

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

<强> backbean（JAVA）：

 private Integer tabIndexTi; // + GETTER, SETTER
 private String tabIndexTs;  // + GETTER, SETTER
 private Long tabIndexTl;    // + GETTER, SETTER

 public Object actionSwitchTab() {   
   System.out.println("  >>>>> actionSwitchTab start; tabIndexTl: " + tabIndexTl);   
   try {    
     Thread.sleep(2000);   
   } catch (InterruptedException ex) {    
     ex.printStackTrace();   
   }   
   System.out.println("  >>>>> actionSwitchTab end");   
   return null;  
  }

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

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

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

在a4j：jsFunction oncomplete事件中调用另一个a4j：jsFunction
