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

我定义了一些Java脚本函数，它们将使用a4j：jsFunction调用后端函数，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，设置onclick属性以像这样调用我定义的函数：

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

单击a4j：commandButton时，将运行＃{Bean1.action1}。返回＃{Bean1.action1}之后，（a4j：jsFunction name =“ function1”）的oncomplete事件
无法调用“＃{Bean1.action2}”。如何解决此问题？

最佳答案

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>

backbean（java）：

 public Object actionSwitchTab() {
   System.out.println("  >>>>> actionSwitchTab start; tabIndexTl: " + tabIndexTl);
   try {

     ex.printStackTrace();

   System.out.println("  >>>>> actionSwitchTab end");
   return null;
