Accessing javascript (Jquery) variables from Apache Wicket

问题

I'm a noob learning Wicket/Jquery. I'm trying to access JavaScript (Jquery) variables from Wicket. Here's an example I'm working with:

        Component slider = new WebMarkupContainer("slider").add(new SliderBehavior(
            new SliderOptions().changeEvent("alert('clicked!')").orientation(Orientation.HORIZONTAL).min(10).max(100).value(20)));

I'm implementing here a jqwicket slider example. Instead of the "alert('clicked!')" event I would like to read the value of the slider to the java. All help appreciated!!!

回答1:

you have to combine jquery's "changeEvent" with the ajax request sending current slider value to your wicket component.

jqwicket contains example for doing this. for more information see AjaxSlider here:
