How can I open a modal dialog on PageLoad(), in the constructor of the WebPage and without the AjaxRequestTarget, with Wicket?

The Window. showModalDialog() created and displayed a modal dialog box containing a specified HTML document.
Just replace "Your link text" with what you want the link to say, and paste the modified modal trigger link into your website. Unlike the JavaScript for your modal form, you should paste the modified modal trigger link where you want it to appear on your website. NOTE: Modal trigger links are now each their own link.
I couldn't find a way to open it without an Ajax request, but it's perfectly possible to open it when the page is loaded, with a simple behavior:
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
<html xmlns:wicket="http://wicket.apache.org">
<body>
<div wicket:id="modal"></div>
</body>
</html>
