我正在尝试创建一些CRUD JSF应用程序,并将其编辑/新屏幕实现为模式对话框。问题是我找不到一种方法来进行此操作,而该方法是通过用ajax执行的对话框进行的,并进行新的编辑操作。使用delete可以非常简单(只需使用ajax =“ true”选项即可。)
这是按钮的代码,用于显示对话框
<h:form id="dataForm">
<div class="ui-g">
<div class="ui-g-12 ui-md-9">
<p:dataGrid var="product" value="#{products.productList}" columns="3" layout="grid"
rows="12" paginator="true" id="products"
paginatorTemplate="{CurrentPageReport} {FirstPageLink} {PreviousPageLink} {PageLinks} {NextPageLink} {LastPageLink} {RowsPerPageDropdown}"
rowsPerPageTemplate="6,12,16">
<f:event type="preRenderView" listener="#{products.preloadProductList}" />
<f:facet name="header">
Products
</f:facet>
<p:panel header="#{product.name}" style="text-align:center">
<h:panelGrid columns="1" style="width:100%">
<h:outputText value="#{product.name}"/>
<h:outputText value="#{product.price}"/>
<%-- Here new/edit dialog window is opened --%>
<p:commandLink update=":dataForm:productDetail" oncomplete="PF('productDialog').show()">
Edit
<f:setPropertyActionListener value="#{product}" target="#{products.product}"/>
</p:commandLink>
<p:commandLink update=":dataForm" action="#{products.deleteAction(product)}" ajax="true">
Delete
</p:commandLink>
</h:panelGrid>
</p:panel>
</p:dataGrid>
<ui:include src="WEB-INF/dialogs/edit_product.xhtml"/>
</div>
</div>
</h:form>
这里是对话框窗口,该窗口已移至单独的文件edit_product.xhtml
<ui:composition
xmlns="http://www.w3.org/1999/xhtml"
xmlns:f="http://xmlns.jcp.org/jsf/core"
xmlns:h="http://xmlns.jcp.org/jsf/html"
xmlns:ui="http://xmlns.jcp.org/jsf/facelets"
xmlns:p="http://primefaces.org/ui">
<p:dialog header="Product Info" widgetVar="productDialog" modal="true" showEffect="fade"
hideEffect="fade"
resizable="false">
<p:outputPanel id="productDetail" style="text-align:center;">
<p:panelGrid columns="2" rendered="#{not empty products.product}"
columnClasses="label,value">
<h:outputText value="Id:"/>
<h:outputText value="#{products.id}"/>
<h:outputText value="Name"/>
<h:inputText value="#{products.name}"/>
<h:outputText value="Price"/>
<h:inputText value="#{products.price}"/>
</p:panelGrid>
<h:commandButton value="Save" action="#{products.saveProduct}"/>
</p:outputPanel>
</p:dialog>
</ui:composition>
这里是Managed bean,它由Product dataGrid和对话框窗口使用。
@ManagedBean(name = "products")
@SessionScoped
public class ProductsBean {
private static final Logger logger = LoggerFactory.getLogger(ProductsBean.class);
@Inject
private ProductRepository productRepository;
private Product product;
private Collection<Product> productList;
public void preloadProductList(ComponentSystemEvent event) throws AbortProcessingException {
productList = productRepository.getAll();
}
public String getId() {
return String.valueOf(product.getId());
}
public void setId(String id) {
product.setId(Long.valueOf(id));
}
public String getName() {
return product.getName();
}
public void setName(String name) {
product.setName(name);
}
public int getPrice() {
return product.getPrice();
}
public void setPrice(int price) {
product.setPrice(price);
}
public Product getProduct() {
return this.product;
}
public void setProduct(Product product) {
this.product = product;
}
public Collection<Product> getProductList() {
logger.info("Get product list");
return productList;
}
public void newProductAction() {
this.product = new Product();
}
public void deleteAction(Product product) {
logger.info("Delete product");
productRepository.remove(product);
}
public void saveProduct() {
productRepository.merge(product);
}
}
无论我是否添加了ajax选项,在按下“保存”按钮后是否重新加载整个窗口。您能告诉我实施的正确方向吗?
