wicket - 如何使用检票口隐藏表格

Question

我想根据条件隐藏表格。使用此代码时出错。请帮助我解决此错误。

//IN 检票口：

<table class="jtrac jtrac-view" width="100%" wicket:id="request">
        <tr>
            <td ></td>
            <td ></td>
        </tr>
</table>
<table class="jtrac jtrac-view" width="100%" wicket:id="response">
        <tr >
            <td ></td>
            <td ></td>
        </tr>
</table>

I wrote java code like this.

WebMarkupContainer request = new WebMarkupContainer("request");
WebMarkupContainer response= new WebMarkupContainer("response");
add(request );
add(response);

if(time == null || time.equals("")) {           
response.setVisible(false);
add(response);          
}else {         
request.setVisible(false);
add(request);
}

Answer 1

   add(request());
   add(response());

   private WebMarkupContainer request() {
      WebMarkupContainer r = new WebMarkupContainer("request") {

         @Override
         protected void onConfigure() {
            super.onConfigure();
            setVisible(StringUtils.isEmpty(time))
         }

      };
      r.setOutputMarkupPlaceholderTag(true);
      return r;
   }

   private WebMarkupContainer response() {
      WebMarkupContainer r = new WebMarkupContainer("response") {

         @Override
         protected void onConfigure() {
            super.onConfigure();
            setVisible(StringUtils.isNotEmpty(time));
         }

      };
      r.setOutputMarkupPlaceholderTag(true);
      return r;
   }
