Question

我想使用inlinframe来显示弹出预览打印页面，这是我的问题：

爪哇：

Form form = new Form("form");
form.setOutputMarkupId(true);
form.add(new AjaxSubmitLink("test") {
    @Override
    protected void onSubmit(AjaxRequestTarget art, Form<?> form) {
        containerPrint.add(/*another inlineframe*/)
        art.addComponent(containerPrint);
    }
});
add(form);

HTML：

<form wicket:id="form">
    <input type="button" wicket:id="test"></input>
</form>
<div wicket:id="page" style="width: 0px;height: 0px">
    <iframe wicket:id="printPage" width="0px" height="0px">
    </iframe>
</div>

我想通过点击测试按钮将inlineiframe替换为另一个inlineiframe 但是点击按钮即可获得此问题

我已经知道问题在于：

container.add(new InlineFrame("printPage", new EmptyPage()));

当我用标签替换它时它的工作正常，但我不知道这是什么问题

问题是什么并不完全清楚（有些代码显然缺失了）。看起来您正在添加新组件，而不是替换旧组件。

试试这样：

public class HomePage extends WebPage {
    private InlineFrame iframe = new InlineFrame("iframe", new OtherPage());

    public HomePage() {
        iframe.setOutputMarkupId(true);

        Form form = new Form("form");
        form.setOutputMarkupId(true);
        form.add(new AjaxSubmitLink("test") {
            @Override
            protected void onSubmit(AjaxRequestTarget art, Form<?> form) {
                InlineFrame newIframe = new InlineFrame("iframe", new OtherPage());
                iframe.replaceWith(newIframe);
                iframe = newIframe;
                art.add(iframe);
            }
        });
        add(form, iframe);
    }
}

非常重要

调用replaceWith以便Wicket可以相应地更新组件树
将您对iframe的引用更改为指向新组件

只需替换上一帧

        @Override
        public void onClick(AjaxRequestTarget target) {
            InlineFrame newIframe = new InlineFrame("iframe", PersonalInformationPage.class);
            iframe.replaceWith(newIframe);
            iframe = newIframe;
            target.add(iframe);
        }

在wicket中使用inlineframe来打印弹出窗口
