Question

我使用的是primefaces 3.5并希望将我的数据表导出为pdf或xml。我没有得到任何错误，但它不起作用。当我点击按钮时，页面只会自我刷新。另外我添加了poi-3.9.jar和itextpdf，但我得到了相同的结果。

Answer 1

尝试使用此依赖项：

        <dependency>
        <groupId>com.lowagie</groupId>
        <artifactId>itext</artifactId>
        <version>2.1.7</version>
    </dependency>

    <dependency>
        <groupId>org.apache.poi</groupId>
        <artifactId>poi</artifactId>
        <version>3.7</version>
    </dependency>

如果您不使用maven，请手动下载。另外，请确保在p：commandLink中使用'ajax = false'属性。

Answer 2

请尝试以下代码。你必须ajax = false。我建议使用primefaces commandlink，但这是可选的。

  <p:commandLink ajax="false">
            <p:graphicImage value="xml.png" />
            <p:dataExporter type="xml" target="datatbl" fileName="myxml" />
   </p:commandLink>

Answer 3

试试这个;的即时=＆＃34;真＆＃34;

<p:commandLink ajax="false" immediate="true"> <p:graphicImage value="xml.png" /> <p:dataExporter type="xml" target="datatbl" fileName="myxml" /> </p:commandLink>

Answer 4

我认为您的问题出在commandLink中，试试这个：

$cart = Mage::getSingleton('checkout/cart');
$cart->addProduct($product, 1); // 1 = qty. Pass your qty and params.

$item = $cart->getQuote()->getItemByProduct($product);
$item->setCustomPrice(0); // or some other value
$item->setOriginalCustomPrice(0); // or some other value
$item->getProduct()->setIsSuperMode(true); // this is crucial 

$cart->save();
Mage::getSingleton('checkout/session')->setCartWasUpdated(true);

Primefaces xml，pdf数据导出不起作用
