如何在PageLoad上打开ModalDialog

如何在AjaxRequestTarget的构造函数中使用Wicket在PageLoad()上打开模式对话框，而不使用AjaxRequestTarget ？

Answer 1

在没有Ajax请求的情况下我找不到打开它的方法，但是在页面加载时完全可以打开它，只有一个简单的行为：

HomePage.java

 public class HomePage extends WebPage { public HomePage(PageParameters pageParameters) { super(pageParameters); ModalWindow modal = new ModalWindow("modal"); modal.add(new OpenWindowOnLoadBehavior()); modal.setPageCreator(new ModalWindow.PageCreator() { @Override public Page createPage() { return new RedirectPage("http://www.google.com"); } }); add(modal); } } 

OpenWindowOnLoadBehavior.java

 public class OpenWindowOnLoadBehavior extends AbstractDefaultAjaxBehavior { @Override protected void respond(AjaxRequestTarget target) { ModalWindow window = (ModalWindow) getComponent(); window.show(target); } @Override public void renderHead(IHeaderResponse response) { response.renderOnLoadJavascript(getCallbackScript().toString()); } } 

HomePage.html

Answer 2

在Wicket Wiki中描述的页面加载（不涉及AJAX）上打开模态窗口

  /** * @author Ernesto Reinaldo Barreiro */ public class OpenOnLoadModalWindow extends ModalWindow implements IHeaderContributor { private static final long serialVersionUID = 1L; /** * @param id */ public OpenOnLoadModalWindow(String id) { super(id); } /** * @param id * @param model */ public OpenOnLoadModalWindow(String id, IModel model) { super(id, model); } /** * Adds the JavaScript to initially open modal window. */ public void renderHead(IHeaderResponse response) { response.renderOnDomReadyJavascript(getWindowOpenJavascript()); } /* * (non-Javadoc) * @see org.apache.wicket.extensions.ajax.markup.html.modal.ModalWindow#makeContentVisible() */ @Override protected boolean makeContentVisible() { return true; } }
