Question

我有这个命令按钮

<p:commandButton onclick="confirmation1.show()"
                                                                 id="delFriend" title="Delete #{userFriend.profileFullname}" icon="ui-icon ui-icon-trash" >

                                                </p:commandButton>

这是确认对话框

<p:confirmDialog id="confirmDialog" message="Are you sure you want to delete this friend ?"
                                                             header="Deleting friend" severity="alert" widgetVar="confirmation1">


                                                <p:commandButton id="confirm" value="Yes Sure" oncomplete="confirmation1.hide()"
                                                                 action="#{messagesManagedBean.deleteFriend}">
                                                    <f:param value="#{profileId}" name="profileId" />
                                                </p:commandButton>
                                                <p:commandButton id="decline" value="Not Yet" onclick="confirmation1.hide()" type="button" />
                                            </p:confirmDialog>

两者都在ui中：重复，当我点击确认对话框中的“肯定”按钮时，它会获取ui：repeat列表中最后一个元素的profileId。

我尝试了f：param方法然后尝试在bean中获取请求参数但是徒劳无功。它做同样的事情。

需要帮助。感谢

在BalusC的回复之后。但它不起作用，使用update =“：interestExpressionsForm：confirmDialog” 确认对话框打开然后立即关闭。

Answer 1

将<p:confirmDialog>放在<ui:repeat>之外。你只需要一个，而不是多个。只需ajax - 根据按下的按钮相应地更新对话框的内容。

在JSF中：ui：repeat confirmdialog获取列表中最后一个元素的id
