如何添加按钮或链接到标准控制器与应用标签不同的visualforce页面？

<apex:page standardController="Account">
    <!-- 页面内容 -->
</apex:page>

<apex:commandButton action="{!nextPage}" value="下一页" />

<apex:outputLink value="/apex/YourPageName?id={!recordId}">下一页</apex:outputLink>

<apex:actionFunction name="nextPage" action="{!nextPage}" rerender="pageContent" />

public PageReference nextPage() {
    PageReference pageRef = new PageReference('/apex/YourPageName');
    pageRef.setRedirect(true);
    return pageRef;
}

public class YourAppController {
    public PageReference nextPage() {
        PageReference pageRef = new PageReference('/apex/YourPageName');
        pageRef.setRedirect(true);
        return pageRef;
    }
}
