来自Apache Wicket的访问的JavaScript（jQuery的）变量 [英] Accessing javascript (Jquery) variables from Apache Wicket

问题描述

我是一个小白学习检票/ jQuery的。我试图从检票访问的JavaScript（jQuery的）变量。下面是我工作的例子：

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)));

我在这里实现jqwicket滑块的例子。取而代之的是警戒（'点击！'）的事件中，我想读滑块到Java的价值。所有帮助AP preciated！

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!!!

推荐答案

你有jQuery的changeEvent中用Ajax请求发送当前滑块值到你的检票口组件相结合。

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

jqwicket包含例如这样做。有关详细信息，请参阅AjaxSlider这里：

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