Page Edited : WICKET : Adding _javascript_ or CSS using a Resource Adding _javascript_ or CSS using a Resource has been edited by Alessandro Vincelli (Apr 02, 2009). (View changes) Content: A quick howto on adding _javascript_ or CSS to your pages, and having them compressed during the "deployment" cycle automatically by Wicket. So to start with, we need to copy or _javascript_ or CSS file somewhere in our package hierarchy that we can reference in our Page. For simplicity, we can copy it right next to the HTML file like so: MyPage.java MyPage.html MyPage.js MyPage.css Then in our Page, we need to reference these items based on the path of our Java file, like so: private static final CompressedResourceReference MYPAGE_JS = new CompressedResourceReference(MyPage.class, "MyPage.js"); private static final CompressedResourceReference MYPAGE_CSS = new CompressedResourceReference(MyPage.class, "MyPage.css"); This code gives us a ResourceReference that we can add to our page, most use cases to the HTML head element block. To do that in your page: add(HeaderContributor.forJavaScript( MYPAGE_JS )); add(HeaderContributor.forCss( MYPAGE_CSS )); In Wicket 1.4 HeaderContributor.forJavaScript() and HeaderContributor.forCss() are deprecated, you can use the code below: add(_javascript_PackageResource.getHeaderContribution(MYPAGE_JS)); add(CSSPackageResource.getHeaderContribution(MYPAGE_CSS));
