在Wicket 6之前,單擊後立即執行由IAjaxCallDecorator.decorateScipt返回的JavaScript代碼。我根據migration-guide遷移了IAjaxCallDecorator。 點擊3次節5秒內預期的結果是:Wicket 6.3.0 AjaxLink:IAjaxCallListener行爲

  • getPrecondition
  • getPrecondition
  • getPrecondition
  • getSuccessHandler
  • getSuccessHandler
  • getSuccessHandler

但結果是:

  • getPrecondition
  • getSuccessHandler
  • getPrecondition
  • getSuccessHandler
  • getPrecondition
  • getSuccessHandler

使用案例:阻塞,直到一個Ajax請求完成看http://my.safaribooksonline.com/book/-/9781849511605/deeper-into-ajax/ch07lvl1sec04(頁162 )

是否有另一種方法將IAjaxCallDecorator遷移到Wicket 6?

public class HomePage extends WebPage { 

public HomePage(final PageParameters parameters) { 
    add(new Label("version", getApplication().getFrameworkSettings().getVersion())); 

    AjaxLink<Void> blockingLink = new AjaxLink<Void>("blockingLink") { 
    @Override 
    public void onClick(AjaxRequestTarget target) { 
     try { 
     Thread.sleep(5000); 
     } catch (InterruptedException e) { 
     e.printStackTrace(); 
     } 
    } 
    @Override 
    protected void updateAjaxAttributes(AjaxRequestAttributes attributes) { 
     super.updateAjaxAttributes(attributes); 

     IAjaxCallListener blockingListener = new AjaxCallListener() { 
     @Override 
     public CharSequence getPrecondition(Component component) { 
      return "console.log('getPrecondition');"; 
     } 
     @Override 
     public CharSequence getSuccessHandler(Component component) { 
      return "console.log('getSuccessHandler');"; 
     } 
     }; 
     attributes.getAjaxCallListeners().add(blockingListener); 
    } 
    }; 
    add(blockingLink); 
} 
}

AFAICS在調用進入隊列之前,沒有調用*的方法。你需要做什麼? – svenmeier

阻塞,直到Ajax請求完成請參閱http://my.safaribooksonline.com/book/-/9781849511605/deeper-into-ajax/ch07lvl1sec04 – user1518456
