在onclick事件之前执行p:commandLink动作? [英] Execute p:commandLink action before onclick event?

问题描述

我有一个p:commandLink，它会在单击时启动一个对话框.此外，还有一个动作，必须在启动对话框之前执行，因为该对话框取决于该动作所填充的内容.

I have a p:commandLink which launches a dialog on click. Further there is an action, which must be executed before launching the dialog, as the dialog depends on the content the action populates.

如何在没有弹出 javascript的情况下启动弹出窗口之前执行操作?

How can I run the action before launching the popup without javascript?

<p:commandLink action="#{service.computePrefetch(_var)}" onclick="dlg.show()"/>

推荐答案

具有oncomplete属性和ajax update属性.

With the oncomplete attribute and the ajax update attribute.

<p:commandLink action="#{service.computePrefetch(_var)}" update="dlgId" oncomplete="dlg.show()"/>

执行顺序:

onclick->操作->更新->未完成

onclick->action->update->oncomplete
