jsf中的按钮加弹框的两种形式

第一种：

                     action="#{ProjectPackageManageBackingBean.removeItems}"
                     styleClass="right_btnserach pull-right">
                     <p:confirm header="一键移除安装工程" message="你确定要移除吗？"
                         icon="pi pi-exclamation-triangle" />
     </p:commandButton>

                     oncomplete="PF('dlg4').show();" update=":form:dlg4"
                     styleClass="right_btnserach pull-right" style="margin-bottom:5px;margin-left:20px">
                 </p:commandLink>

 <p:dialog header="一键分配安装工程量" widgetVar="dlg4" modal="true" dynamic="true" id="dlg4"
     resizable="false" width="550px" height="auto">
     <t:div styleClass="right_popup_content" id="azgcfeipeicontend" width="385px">
     <t:div styleClass="right_popup_projectinfo">
             <t:panelGrid styleClass="right_main_info" columns="2"
                 columnClasses="right_main_th,right_main_t2">

                     <h:outputText value="选择部门 :" />
                 </t:panelGroup>
                 <p:selectOneMenu styleClass="right_menu right_menu_sp5"
                     id="groupInfoUserListdemo"
                     value="#{ProjectPackageManageBackingBean.assignGroupName}">
                     <f:selectItem itemLabel="" itemValue=""></f:selectItem>
                     <f:selectItems value="#{ProjectPackageManageBackingBean.groupListSelectItems}"></f:selectItems>
                     <p:ajax event="change" update="azgcfeipeicontend"></p:ajax>
                 </p:selectOneMenu>
                 <t:panelGroup>
                     <h:outputText value="选择人员 :" />
                 </t:panelGroup>
                 <t:div styleClass="right_fenpei_content">
                 <t:div styleClass="right_main_fenpei_item" id="submitcheckb4">
                         <p:selectOneRadio id="items" value="#{ProjectPackageManageBackingBean.assignChecked}" layout="grid" columns="3"
                             forceId="true" forceIdIndex="false" >
                             <f:selectItems
                                 value="#{ProjectPackageManageBackingBean.assignUserCheckBoxList}"
                                 var="items" itemLabel="#{items.name}" itemValue="#{items.id}" />
                         </p:selectOneRadio>
                 </t:div>
                 </t:div>
             </t:panelGrid>
         </t:div>
     </t:div>
     <f:facet name="footer">
         <p:commandLink value="确定" styleClass="btn btn-primary margin-right"
             action="#{ProjectPackageManageBackingBean.takeMission}"
             update=":form:message,:form:tab:azTree,:form:dlg4"
             onclick="PF('dlg4').hide();">
         </p:commandLink>
         <p:commandLink value="取消" styleClass="btn btn-default"
             onclick="PF('dlg4').hide();">
         </p:commandLink>
     </f:facet>
 </p:dialog>
