jsf中的按钮加弹框的两种形式

第一种：

    <p:commandButton value="一键移除"
                    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">
                <t:panelGroup>
                    <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>
