在下面的代码中，命令按钮不适用于数据表。
<p:dataTable id="invoiceTable" var="ipsDetail"
value="#{invoiceBean.ipsDetails}" border="1">
<p:column headerText="Sr. No.">
<h:inputText id="serialN7umber" value="#{ipsDetail.serialNumber}"
size="3" />
</p:column>
<p:column headerText="Description of Goods">
<p:inputText value="#{ipsDetail.descriptionOfGoodsOrService}" />
</p:column>
<p:column headerText="HSN Code">
<p:inputText value="#{ipsDetail.hsnCode}" styleClass="Alingment" />
</p:column>
<p:column headerText="Quantity">
<p:inputText value="#{ipsDetail.quantity}" styleClass="Alingment" />
</p:column>
<p:column headerText="Rate">
<p:inputText value="#{ipsDetail.rate}" styleClass="Alingment" />
</p:column>
<p:column headerText="Percentage Discount">
<p:inputText value="hello" rendered="#{ipsDetail.percentDiscount}"
styleClass="Alingment" />
</p:column>
<p:column headerText="Amount">
<p:inputText value="#{invoiceBean.amount}" styleClass="Alingment" />
</p:column>
<f:facet name="footer">
<p:commandButton value="Add New Row" action="#{invoiceBean.addRow}" update=":form:invoiceTable">
<!-- <f:ajax execute=":form:invoiceTable" render=":invoiceTable:addColumn" /> -->
</p:commandButton>
</f:facet>
</p:dataTable>
</h:form>
我想在Java中使用primefaces命令按钮使用inputtext添加动态行。它可以工作，但无法重新渲染。
公共类InvoiceBean实现Serializable {
公共列表getInvoices（）{
InvoiceDao invoiceDao = new InvoiceDao();
invoices = invoiceDao.getInvoiceData();
return invoices;
}
public void setInvoices(List<Invoice> invoices) {
if (invoices != null) {
this.invoices.add(new Invoice());
}
}
public void getInvoiceData() {
InvoiceDao invoiceDao = new InvoiceDao();
ipsDetail = new InvoiceProductsServicesDetail();
if ( ipsDetail != null) {
ipsDetail
.setDescriptionOfGoodsOrService(descriptionOfGoodsOrService);
ipsDetail.setHsnCode(hsnCode);
ipsDetail.setInvoiceId(invoice.getId());
ipsDetail.setPercentDiscount(percentDiscount);
ipsDetail.setQuantity(quantity);
ipsDetail.setRate(rate);
ipsDetail.setSerialNumber(serialNumber);
ipsDetail.setServiceTax((float) 12.5);
ipsDetail.setVat(5);
System.out.println("InvoiceBean.insertInvoice");
}
invoiceDao.insertInvoice(invoice, ipsDetail);
}
public Row addRow() {
Row row = new Row();
InputText inputText = new InputText();
inputText.setSubmittedValue("Hello");
Column column = new Column();
row.setParent(inputText);
column.setHeader(inputText);
column.setHeaderText("Hardik");
return row;
}
这是使用inputtext添加行或列的代码
由于您使用的是Primefaces，因此您还可以使用org.primefaces.context.RequestContext对象从ManagedBean本身更新任何组件。
例如：
小面：
<h:form id="form1">
<p:dataTable id="myTab">
...
</p:dataTable>
</h:form>
ManagedBean：
RequestContext reqCtx = Requestcontext.getCurrentInstance();
req.Ctx.update("form1:myTab");
