Wicket Ajax Modal ‘Are you sure?’ window

Feb 2

While developing web application with Wicket I sometimes need to check whether the user really, really does want to do something, for example to delete an entity from the database. The first and easiest choice that comes to my mind is to use JavaScript window.

So we have HomePage.html:

<!DOCTYPE html
    PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
    "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns:wicket="http://wicket.apache.org/dtds.data/wicket-xhtml1.4-strict.dtd" >
    <head>
        <title>Wicket Ajax 'Are you sure?' Modal Window</title>
    </head>
    <body>

        <div align="center">
            <strong>Wicket Ajax 'Are you sure?' Modal Window</strong>

            <form action="" wicket:id="formWithJavaScript">
                <input type="submit" wicket:id="buttonWithJavaScript" value="Action!"/>
            </form>
        </div>

    </body>
</html>

and corresponding Java class:

package pl.tdziurko.ajaxmodalwindowapp;

// imports omitted

public class HomePage extends WebPage {

    private static final long serialVersionUID = 1L;

    public HomePage(final PageParameters parameters) {

        Form formWithJavaScript = new Form("formWithJavaScript");

        Button buttonWithJavaScript = new Button("buttonWithJavaScript") {

            @Override
            public void onSubmit() {
                System.out.println("Doing my job");
            }
        };
        buttonWithJavaScript.add(new SimpleAttributeModifier(
                "onclick", "if(!confirm('Do you really want to perform this action?')) return false;"));

        formWithJavaScript.add(buttonWithJavaScript);
        add(formWithJavaScript);

    }

}

Finally, we can see how it looks:

It solves our problem but in the era of Web2.0, rounded corners and shiny looks it isn’t enough. Why can’t we use ajax modal window to ask user for confirmation? It would make our application look good and our css magician could make it look even better. Continue reading this post …
