如何在 PageLoad() 的构造函数中打开一个模式对话框，在没有 AjaxRequestTarget 的情况下使用 Wicket?
How can I open a modal dialog on PageLoad(), in the constructor of the WebPage and without the AjaxRequestTarget, with Wicket?
如果没有 Ajax 请求，我找不到打开它的方法，但是完全可以在页面加载时打开它，只需一个简单的行为:
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
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
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());
}
}
