Question

我目前正在使用JSF2.0创建一个Facelets页面，我正在使用Primefaces使它看起来很花哨：D。但我有一个我似乎无法解决的问题。我的页面背后的想法如下：我有一个仪表板页面，其中包含不同的手风琴选项卡，每个选项卡中都有一个primefaces数据表。在该数据表中是给定用户的一些行。但是当我想在我的数据表中添加一个新行时，我使用以下方法。我的数据表下面有一个“添加行”按钮，当我点击它时，我将JQuery页面加载到我按钮下方的div中。那个div就是我的“addrow”页面加载了验证等等。

但问题是：当我点击包含页面上的添加按钮时，我想在“父”页面中更新我的数据表，所以包含我的添加页面的页面，这不是作为我的p的更新属性：commandButton似乎没有在我的父页面上找到数据表或任何其他组件。

所以如果有人能告诉我如何在父页面中更新我的组件？

以下是相关的代码片段： 父页面（包括“内容div”中的添加页面）

            <div id="content">

            </div>

添加页面

            <f:view contentType="text/html">
            <ui:composition>
                <h:form id="companyForm" prependId="false">
                    <h:message for="name"/>
                    <h:message for="startdate"/>
                    <h:message for="enddate"/>

                    <h:outputText class="label" value="name: "/>
                    <h:inputText id="name" styleClass="inputtext validate[required]"
                                 value="#{companyBean.companyName}"/>
                    <h:outputText class="label" value="start date: "/>
                    <h:inputText id="startdate" styleClass="inputtext validate[required]"
                                 value="#{companyBean.startDate}">
                        <f:convertDateTime pattern="dd/MM/yyyy"/>
                    </h:inputText>
                    <h:outputText class="label" value="end date: "/>
                    <h:inputText id="enddate" styleClass="inputtext validate[required]"
                                 value="#{companyBean.endDate}">
                        <f:convertDateTime pattern="dd/MM/yyyy"/>
                    </h:inputText>

                    <h:outputText class="label" value="type: "/>
                    <h:selectOneMenu styleClass="input" value="#{companyBean.type}">
                        <f:selectItem itemValue="0" itemLabel="Internal"/>
                        <f:selectItem itemValue="1" itemLabel="External"/>
                    </h:selectOneMenu>

                    <h:commandButton action="cancel" value="cancel" immediate="true"/>
                    <p:commandButton id="btnAddCompanyTest" actionListener="#{companyBean.addCompany}" value="Add company" ajax="false"/>

                </h:form>
            </ui:composition>
        </f:view>

JQuery加载方法

jQuery("#btnAddCompany").click(function() {
    jQuery("#content").load('/user/companyDetail.xhtml',function(){
        jQuery("#companyForm").validationEngine('attach', {promptPosition : "topRight", scroll: false});
    });
});

支持bean添加方法

public String addCompany() {
        FacesContext facesContext = FacesContext.getCurrentInstance();
        try {
            companyService.addCompany(companyName, startDate, endDate, type);
            loadCompanyList();
        } catch (cvApplicationException e) {
            facesContext.addMessage("companyForm", new FacesMessage(e.getMessage()));
        }
        return "../user/dashboard.xhtml?faces-redirect=true";
    }

我的backingBean是sessioncoped。

Answer 1

标题

而是使用jQuery（..）加载.load（）为什么不在div元素中使用。

        <div id="content">
            <p:outputPanel id="" rendered="#{companyBean.insertMode}">
                <!--  put your add page here -->
            </p:outputPanel>
        </div>

您只需设置isInsertMode（）方法即可返回true或false。所以你将在同一个视图页面中。从添加页面更新数据表可能有效。

也是Backing bean

public class CompanyBean {

private List<Company> list;


private TestController(){
    list = new ArrayList<Company>();

            //populate data, should be from database
