在jsf中返回命令按钮 [英] back commandbutton in jsf

问题描述

如何将后退按钮实现为一个普遍适用的命令按钮？使用后退按钮我不是指浏览器按钮，而是位于页面某处的按钮。并不总是可以使用Post-redirect-get模式。

how would one implement a back-button as a commandbutton that works universally? with back button i don't mean the browser-button, but rather a button that sits somewhere on the page. it is not always possible to use the Post-redirect-get pattern.

传递按钮应该指向的每一个信息是非常不可靠的。

its quite impractial to pass around the information on every single where the button should point to.

是否可能有导航规则的保留关键字指向应用的上一个导航规则？

is there maybe a reserved keyword for a navigation rule that points to the last navigation rule applied?

推荐答案

我使用 h：commandLink ，其属性为 onclick =history.go（-1）在这种情况下。它普遍适用。

I use a h:commandLink with attribute onclick="history.go(-1)" in this case. It works universally.
