PrimeFaces commandButton不会导航或更新

问题描述

我正在使用Primefaces使我的应用程序更加美观.我注意到p:commandButton和h:commandButton的工作方式不同.

I'am using Primefaces to make my app a little bit more beautiful. I noticed that p:commandButton and h:commandButton don't work the same way.

p:commandButton调用该方法，没有其他发生. h:commandButton调用该方法并返回导航.

The p:commandButton calls the method and nothing else hapens. The h:commandButton calls the method and returns a navigation.

在使用p:commandButton时，按下登录按钮后，我在重定向方面遇到了麻烦.该如何处理?

I have got trouble with redirecting after pressing the login button when using p:commandButton. How to deal with that?

我确实有一个更新参数:

I do have an update parameter:

<p:commandButton value="Login" action="#{login.login}" type="submit" update="msgs" />

推荐答案

<p:commandButton>需要以下条件之一才能正常工作:

<p:commandButton> needs one of the following to work correctly:

• update属性以列出要重新呈现的组件ID(用于AJAX请求)
• 属性ajax="false"可以正常，非ajax提交.

• the update attribute to list id's of components to re-render (for AJAX requests)
• the attribute ajax="false" to make a normal, non-ajax submit.

如果您都不选择该按钮，则默认情况下该按钮会执行AJAX请求，而不会提供用户界面反馈.

If you have neither, the button does per default an AJAX request with no UI feedback.

此外，当周围的<h:form>具有enctype属性时，我都无法使用这两个选项.

Additionally, I've had problems with neither option working when the surrounding <h:form> had an enctype attribute.
