Primefaces onclick 和 onsuccess 差异 [英] Primefaces onclick and onsuccess differences

问题描述

我有以下情况:

点击一个按钮后，一些业务逻辑就完成了，完成后，一个带有报告的新标签应该是可见的.

after clicking a button, some business logic is done and after it is done, a new tab with a report should be visible.

<p:commandButton value="this button" update="growlMain"
                 actionListener="#{myBean.businesslogic}" 
                 onstart="ajaxDialog.show();"
                 oncomplete="ajaxDialog.hide();"
                 onsuccess="window.open('./report.jsp', '_newtab');" />

这不起作用:(

如果业务逻辑只持续几毫秒，则以下工作:

If the business logic only lasts some milliseconds, the following works:

<p:commandButton value="this button" update="growlMain"
                 actionListener="#{myBean.fastbusinesslogic}" 
                 onclick="window.open('./report.jsp', '_newtab');" />

onclick 会打开一个新选项卡，还有 onstart 之类的东西，但它不适用于 onsuccess 或 oncomplete.为什么?是否有针对持续几秒钟的业务逻辑的解决方案?

the onclick opens a new tab, also things like onstart but it doesn't work with onsuccess or oncomplete. Why? And is there a solution for business logic that lasts some seconds?

推荐答案

我注意到 PrimeFaces 命令按钮的 onsuccess 不起作用.但是，即使出现错误， oncomplete 也能正常工作并执行必要的操作，例如在我的情况下，即使我的业务逻辑中存在错误，也会显示成功对话框.尝试使用 onsuccess 但不起作用.您可以尝试如下完成:

I have noticed that onsuccess for PrimeFaces command button does not work. The oncomplete however works and does the needful even if there is an error , such as in my case shows a success dialog even if there is an error in my business logic. Tried to use onsuccess but doesn't work. You could try oncomplete as below:

<p:commandButton value="this button" update="growlMain"
                 actionListener="#{myBean.businesslogic}" 
                 onstart="ajaxDialog.show();"
                 oncomplete="ajaxDialog.hide(); window.open('./report.jsp', '_newtab');"/>
