Question

我有一个MyArticlePresenter.java（在客户端包中）。它的网址是＆＃34; mydomain.com＃！article＆＃34;：

MyArticlePresenter.java有一个RPC来调用文章。我希望在从数据库获取articleData之后，它将清除该GWT页面中的所有内容。然后将整个GWT页面重置为新的<html>

private AsyncCallback<GetArticleResult> getArticleCallback=new AsyncCallback<GetArticleResult>(){
    @Override
public void onSuccess(GetArticleResult result) {
        String articleData=result.getArticleData;

        RootPanel.getBodyElement().setInnerHTML("<html>"+articleData+"</html>");

    }
}

然而，我收到了一个错误。

你能找到一个优雅地重置整个GWT页面的方法吗？

Answer 1

似乎这是解决方案：

          Scheduler.get().scheduleDeferred(new ScheduledCommand() {

                @Override
                public void execute() {
                    RootPanel.getBodyElement().setInnerHTML("<html>"+articleData+"</html>");
                }
          });

如何为整个GWT页面手动重置HTML？
