Question

这是我在一个数据表列中的commandButton，其作用是删除关联的行对象：

   <p:column style="width:6%;text-align:center"
   headerText="Delete">
    <p:commandButton icon="ui-icon-close"
     title="Delete release #{release.name}"
     actionListener="#{releaseBean.deleteRelease(release)}"
     process="@this" update=":display :form2:releaseList">
        <p:confirm
          header="Confirm deleting release #{release.name}"
          message="Are you really sure you want to delete release #{release.name}?"
          icon="ui-icon-alert" />
    </p:commandButton>
   </p:column>

我希望发布的名称显示在删除确认消息中（您确定要删除版本＆＃34; XYZ＆＃34;？）..但问题是版本的名称＆＃34; XYZ＆＃34;在消息中既不显示也不在<p:confirm>的标题中;但它显示在<p:commandButton>标题中。

我做错了什么？谢谢。

编辑：

我尝试修改commandButton并添加setPropertyActionListener：

    <p:commandButton icon="ui-icon-close"
         title="Delete release #{release.name}"
         actionListener="#{releaseBean.deleteRelease(release)}"
         process="@this" update=":display :form2:releaseList">
         <f:setPropertyActionListener
         target="#{gestionReleaseBean.selectedRelease}"
         value="#{release}" />            
         <p:confirm
              header="Confirm deleting release #{release.name}"
              message="Are you really sure you want to delete release #{release.name}?"
              icon="ui-icon-alert" />
    </p:commandButton>

在bean中我添加了属性selectedRelease以及它的getter / setter。

它没有工作......

如果你不介意一些额外的代码行，那么你可以实现如下，

首先放置一个对话框的数据表

<p:dialog modal="true" header="Confirm" widgetVar="wgc" >
 <h:outputText id="msg" />
 <h:inputHidden id="idh" value="#{releaseBean.id}" />
 <p:commandButton value="Delete" action="#{bean.delete()}" />
 <p:commandButton value="Cancel" type="button" onclick="PF('wgc').hide()" />
</p:dialog>

在您的javascript部分添加此

function confirm(id,name){
 document.getElementById('msg').innerHtml='Are you sure to delete ' +  name;
 document.getElementById('idh').value=id;
 PF('wgc').show();
}

然后在datatable删除按钮

<p:commandButon type="button" 
                value="Delete" 
                onclick="confirm(#{release.id},'#{release.name}')" />

删除确认对话框中无法显示对象详细信息
