Hi All,
I have looked in to this topic in many places and found some ways. In this
particular scenario, I have used
https://cwiki.apache.org/confluence/display/WICKET/Calling+Wicket+from+Javascriptarticle
as the reference.
What I did in Java,
public class HomePage extends WebPage {
private static final long serialVersionUID = 1L;
public HomePage(final PageParameters parameters) {
super(parameters);
final AbstractDefaultAjaxBehavior behave = new
AbstractDefaultAjaxBehavior() {
protected void respond(final AjaxRequestTarget target) {
target.add(new Label("foo", "Yeah I was just called from
Javascript!"));
public void renderHead(Component component,IHeaderResponse
response){
String componentMarkupId = component.getMarkupId();
String callbackUrl = getCallbackUrl().toString();
response.render(JavaScriptHeaderItem.forScript("var
componentMarkupId='"+componentMarkupId+"'; var
callbackUrl='"+callbackUrl+"';","values"));
};
add(behave);
and my HomePage.html,
<!DOCTYPE HTML>
<html>
<body>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.6.1/jquery.min.js
"></script>
<script type="text/javascript">
$(function() {
var wcall = Wicket.Ajax.get({ u: '${callbackUrl}' + '' });
alert(wcall);
});
</script>
</body>
</html>
What I tried to do is call the get ajax method using the vars I have
initialized. But when my page loads, in the firebug console it says,
ReferenceError: Wicket is not defined
[Break On This Error]
var wcall = Wicket.Ajax.get({ u: '${callbackUrl}' + '' });
What has gone wrong here ?
Is there any other good way to call Java Function from Javascript?
Thanks!
