问题描述
我已经做到这一点：
add（new Link（doAnything）{
@Override
public void onClick（）{
//更改文本！
// this.modelChanging（）;
// this.detach（）;
}
}）;
我希望你能给我一些简单的建议 - 我真的很新： p>

解决方案
HTML： p>
< html>< head>< / head>< body>
< wicket：panel>
< a href =wicket：id =link>
< wicket：container wicket：id =label/>
< / a>
< / wicket：panel>
< / body>< / html>
java：
public class MyPanel extends Panel {
private static class Mybean {
String labelText =click me;
public String getLabelText（）{
return this.labelText;
}
public void setLabelText（final String labelText）{
this.labelText = labelText;
}
}
public MyPanel（final String id）{
super（id）;
final Mybean bean = new Mybean（）;
this.add（new Link< Void>（link）{
private static final long serialVersionUID = 1L;
@Override
public void onClick（）{
bean.setLabelText（感谢点击）;
}
} .add（new Label（label，new PropertyModel< String>（bean，labelText ）））
）;
}
}
我倾向于使用wicket：容器，以便不用多余元素污染HTML（小门：容器不会在生产中呈现）
I created a link with static text. That works fine but now I also want to change the text when you click the link.
I got as far as this:
add(new Link("doAnything") {
@Override
public void onClick() {
// change the text!
// this.modelChanging();
// this.detach();
}
});
I hope you can give me some easy advice - I'm really new to this :)

The HTML:
<html><head></head><body>
<wicket:panel>
<a href="" wicket:id="link">
<wicket:container wicket:id="label" />
</a>
</wicket:panel>
</body></html>
The java:
public class MyPanel extends Panel{
private static class Mybean{
String labelText = "click me";
public String getLabelText(){
return this.labelText;
}
public void setLabelText(final String labelText){
this.labelText = labelText;
}
}
public MyPanel(final String id){
super(id);
final Mybean bean = new Mybean();
this.add(new Link<Void>("link"){
private static final long serialVersionUID = 1L;
@Override
public void onClick(){
bean.setLabelText("Thanks for clicking");
}
}.add(new Label("label", new PropertyModel<String>(bean, "labelText")))
);
}
}
I tend to use wicket:container in order to not pollute the HTML with superfluous elements (the wicket:container won't be rendered in production)
