在p:confirmDialog上显示格式化的文本/消息 [英] Display a formatted text / message on p:confirmDialog

问题描述

当 <p:dataTable> 中的一行正确时，单击后，出现 <p:contextMenu> 并带有删除选项.单击此选项后， <p:confirmDialog> 出现并带有两个按钮和No-有关删除当前行的警告，如下所示.

When a row in <p:dataTable> is right-clicked, <p:contextMenu> appears with a delete option. When this option is clicked, <p:confirmDialog> appears with two buttons Yes and No - a conformation warning about deleting the current row as follows.

<p:contextMenu for="dataTable">
    <p:menuitem oncomplete="confirmDelete.show()"
                value="Delete"
                update="confirmDialog"
                process="@this dataTable"
                actionListener="#{testManagedBean.deleteActionListener}"
                icon="ui-icon-close" ajax="true"/>
</p:contextMenu>

<p:confirmDialog id="confirmDialog"
                 widgetVar="confirmDelete"

                 message="#{testManagedBean.message}"

                 header="Message"
                 severity="alert"
                 closeOnEscape="true"
                 showEffect="slide"
                 hideEffect="fold"
                 appendTo="@(body)"
                 closable="true">

    <p:commandButton id="btnYes"
                     value="Yes"
                     process="@this"
                     oncomplete="confirmDelete.hide()"
                     actionListener="#{testManagedBean.deleteActionListener}" 
                     update="dataTable"/>

    <p:commandButton id="btnNo"
                     value="No"
                     onclick="confirmDelete.hide()"
                     type="button" />
</p:confirmDialog>

在此对话框上是否可以用格式化的消息设置message属性.

Is there a way to set the message attribute with a formatted message on this dialog.

例如，其托管bean中的属性testManagedBean.message设置为类似字符串

For example, the property testManagedBean.message in its managed bean is set to a string like

You are about to delete <font color='#ff0000'>2</font> rows. <br/>This action will never be undone. <br/>Are you sure?

确认对话框将整体显示此字符串.此字符串中的HTML应该解释为HTML.我没有在<p:confirmDialog>中看到任何类似escape的属性.

The confirm dialog displays this string as a whole. HTML in this string should be interpreted as HTML. I don't see any attribute like escape in <p:confirmDialog>.

有没有办法将此字符串显示为格式化的消息.

Is there a way to display this string as a formatted message.

推荐答案

我在<p:confirmDialog>中发现了丑陋的解决方案嵌套<f:facet name="message">.

I found an ugly solution nesting of <f:facet name="message"> within <p:confirmDialog>.

<p:confirmDialog id="confirmDialog"
                 widgetVar="confirmDelete"

                 header="Message"
                 severity="alert"
                 closeOnEscape="true"
                 showEffect="slide"
                 hideEffect="fold"
                 appendTo="@(body)"
                 closable="true">

    <p:commandButton id="btnYes"
                     value="Yes"
                     process="@this"
                     oncomplete="confirmDelete.hide()"
                     actionListener="#{testManagedBean.deleteActionListener}"
                     update="dataTable"/>

    <p:commandButton id="btnNo"
                     value="No"
                     onclick="confirmDelete.hide()"
                     type="button" />

    <f:facet name="message">
        <h:outputFormat value="#{testManagedBean.message}" escape="false"/>
    </f:facet>
</p:confirmDialog>

从<p:comfirmDialog>中删除message属性，并将<f:facet name="message">嵌套在其中.

Removing the message attribute from <p:comfirmDialog> and nesting <f:facet name="message"> inside it.

注意:仅当需要通过嵌套<f:param>传递一个或多个参数以替换消息文本中相应占位符({0})时，才需要<h:outputFormat>.如果不需要传递此类参数，请继续使用<h:outputText escape="false">.

Note : <h:outputFormat> is only needed, if one or more parameters need to be passed by means of nested <f:param> to be substituted in respective placeholders ({0}) in the message text. Just keep on using <h:outputText escape="false">, if no such parameters need to be passed.
