如何在 wicket 中手动设置 RadioGroup 值？
我试图在 AjaxEventBehavior 期间更改 Wicket RadioGroup 中选定的单选按钮，但不知道如何执行此操作。具体来说，当用户在文本框中键入一些文本时，我想将选定的单选按钮更改为我指定的单选按钮。你如何做到这一点？
这是我到目前为止所得到的（它在 addComponent 上崩溃）：
myRadioGroup = new RadioGroup("MyNewGroup", new PropertyModel(getPojo(), "selectedGroup"));
Radio internalRadio = new Radio("InternalDirectoryNumber", new Model("Internal"));
myRadioGroup .add(internalRadio);
Radio externalRadio = new Radio("OtherMobileNumber", new Model("External"));
myRadioGroup .add(externalRadio);
TextField myTxtField= new TextField("TextBoxPrivateNumber", new PropertyModel(getVoiceItem(), "privateMobilePhone"));
myTxtField.add( new AjaxEventBehavior( "onKeyUp" )
{
@Override
protected void onEvent(AjaxRequestTarget target)
{
Component component = target.getPage().get("myForm:MyNewGroup").setDefaultModelObject("External");
target.addComponent(component); //this causes an exception
}
});
myRadioGroup .add(myTxtField);
这是抛出的异常。 java.lang.IllegalArgumentException：无法更新没有的组件 setOutputMarkupId 属性设置为 true。成分： [MarkupContainer [Component id = myRadioGroup]]
执行此操作的正确方法是什么？我没有在网上找到大量相关的检票口文档。
I'm trying to change the selected radio button in a Wicket RadioGroup during an AjaxEventBehavior but can't figure out how to do so. Specifically when a user types some text in a textbox I want to change the selected radio button to one I specify. How do you do this?
Here's what I have so far (it crashes on addComponent):
myRadioGroup = new RadioGroup("MyNewGroup", new PropertyModel(getPojo(), "selectedGroup"));
Radio internalRadio = new Radio("InternalDirectoryNumber", new Model("Internal"));
myRadioGroup .add(internalRadio);
Radio externalRadio = new Radio("OtherMobileNumber", new Model("External"));
myRadioGroup .add(externalRadio);
TextField myTxtField= new TextField("TextBoxPrivateNumber", new PropertyModel(getVoiceItem(), "privateMobilePhone"));
myTxtField.add( new AjaxEventBehavior( "onKeyUp" )
{
@Override
protected void onEvent(AjaxRequestTarget target)
{
Component component = target.getPage().get("myForm:MyNewGroup").setDefaultModelObject("External");
target.addComponent(component); //this causes an exception
}
});
myRadioGroup .add(myTxtField);
Here is the exception that's thrown.
java.lang.IllegalArgumentException: cannot update component that does not have
setOutputMarkupId property set to true. Component:
[MarkupContainer [Component id = myRadioGroup]]
What's the proper way to do this? I'm not finding a whole lot of wicket documentation for this online.
