Wicket - 获取标记元素的主体 [英] Wicket - getting body of markup element

问题描述

假设我的标记看起来像这样：

Assuming I have markup that looks like this :

<span wicket:id="text">Some text that I'd like to read</span>

是否可以在某处获取标签正文的内容，或者是否可以通过wicket？

Is it possible to get the content of the body of the tag somewhere, or is it irremediably stripped by wicket?

编辑：
我的目的是实现某种简单的CMS。用户需要能够以 tex> a ^ 2< / tex> 的形式输入LaTeX公式，然后我将使用RenderedDynamicImageResource进行渲染。其他标签需要以类似的方式解释。我设想用 Panel 分两步完成：

Edit : My intent is to implement some kind of simple CMS. Users need to be able to enter LaTeX formulas, in the form of tex>a^2</tex> that I would then render with a RenderedDynamicImageResource. Other tags need to be interpreted in a similar way. I envisioned to do it in two steps with a Panel like this :

public class LightweightMarkupPanel extends Panel implements IComponentResolver {
    public LightweightMarkupPanel ( String id ) {
        super( id );
    }

    @Override
    public MarkupStream getAssociatedMarkupStream( boolean throwException ) {
        // Get the lightweight markup and convert it to wicket markup
        ...
    }

    @Override
    public boolean resolve( MarkupContainer container, MarkupStream markupStream, ComponentTag tag ) {
        // AutoAdd components as needed
        ...
    }
}

我一直在努力解决这个问题，也许我正在寻找错误的方向。

I've been struggling with this problem for a while, so maybe I'm searching in the wrong direction.

推荐答案

MarkupStream Component的对象包含原始HTML主体。
您可以使用markupStream.get（）。toString（）方法检索它，如下所示：

The MarkupStream object of the Component contains the raw HTML body. You can retrieve it using the markupStream.get().toString() method like this:

// <span wicket:id="message">message will be here</span>
add(new Label("message", "If you see this message ..."){
     @Override
     protected void onComponentTagBody(
         MarkupStream markupStream, ComponentTag openTag) {
         markupStream.get(); // "message will be here"
         super.onComponentTagBody(markupStream, openTag);
     }
});
