我需要创建动态确认对话框。我有一个动态创建的CommandButton。因此,当按下时,将显示confirmDialog。我不知道如何在按下CommandButton时显示它。
最佳答案
您的按钮应如下所示:
<p:commandLink oncomplete="confirmation.show()"
action="#{campagneComtroller.messageDeleteCam1(c)}"
update=":frmDlgDel:confirmDialog">
<p:graphicImage value="/image/delete.png" height="20" width="20"/>
</p:commandLink>
您的ConfirmDialog应该如下所示:
<h:form id="frmDlgDel">
<p:confirmDialog id="confirmDialog"
message="#{campagneComtroller.messageDeleteCam1}"
header="#{bundles.messages['message.SupprimerGeneral']}" severity="alert" widgetVar="confirmation">
<p:commandButton id="confirm" value="#{bundles.messages['message.OuiSure']}" oncomplete="confirmation.hide()" update=":formCam :frmDlgDel"
actionListener="#{campagneComtroller.deleteCam1()}" />
<p:commandButton id="decline" value="NonPasEncore" onclick="confirmation.hide()" type="button" />
</p:confirmDialog>
</h:form>
您的Java代码应如下所示:
public void messageDeleteCam1(Cam cam) {
conditionVerified = true; // ... you can put here your treatments
if (conditionVerified) {
messageDeleteCam1 = "this cam is bla bla bla ";
} else {
messageDeleteCam1 = "are you sure to delete this cam ?";
}
}
注意:我们在这里使用了oncomplete + update,这就是为什么我们可以在java处理后在confirmDialog中看到差异。
