Re: [Wicket-develop] ajax call from within client side javascript

Igor Vaynberg Tue, 11 Jul 2006 10:06:48 -0700

ick a soft binding like that will not stand up to refactoring. you are also limited to the page - what if you need this for component - then you are back to the interface idea i mentioned. also the interface defines some useful options for ajax - such as: always use top page version and ignore request if page is not on top of access stack (useful for timing) - once you want all this you are pretty much back to what i mentioned.

wicketAjaxMethodCall("raiseTemperature", "amount=1&person=ivaynberg");

Serverside:

public class MyPage extends WebPage {
    public void raiseTemperature(AjaxRequestTarget target) {
        double amount = /* get amount from request parameters */
        Person person = /* get person from request parameters */
        igor.temperature += amount;
        target.addComponent(thermometer);
    }
}

Substitute ##wicket karma for temperature when you're feeling better ;-)
