我用jsf构建模板。模板的 div 包含另一个 jsf 文件 ////////////////////

<h:panelGroup id="mainCenterBox" styleClass="mainCenterBox" layout="block">
       <ui:include  id="centerView" src="messageBoardView.xhtml"/>
</h:panelGroup>

\\\\\\\\\\\\

当我使用ajax cleck commandButton 时，如何更改ui:include 中的src 以查看其他页面

嗨，谢谢 Vasil Lukach 的重播我不知道如何将参数形式 commandButton 发送到 bean，下面是我的代码

\\\\\\\\\\\\\ The Bean File
import javax.enterprise.context.RequestScoped;
import javax.inject.Named;

@Named("urls")
@RequestScoped

public class URLPagesBean 
{
    private String urlSRC = "";

    public String getUrlSRC() {
        return urlSRC;
    }

    public void setUrlSRC(String urlSRC) {
        this.urlSRC = urlSRC;
    }

    public String getURL()
    {
        String url = "";
        if(urlSRC == "page1" || urlSRC == "" || urlSRC == null)
        {
            url = "page1.xhtml";
        }
        else if (urlSRC == "page2")
        {
            url = "page2.xhtml";
        }
       return url;
    }
}

在模板中，您可以使用ui:insert，例如

<ui:insert name="footer">
    <ui:include src="/WEB-INF/template/footer.xhtml" />
</ui:insert>

在您看来，您可以重新定义它：（<ui:define name="footer"></ui:define>无页脚）或包含其他文件。

如果你需要支持 ajax，那么你可以使用ui:fragment. 它具有rendered可用于显示内容的属性（您可以拥有多个片段）。
