Código de exemplo de anúncio intersticial em JavaScript
Aviso
A partir de 1º de junho de 2020, a plataforma Microsoft Ad Monetization para aplicativos UWP do Windows será desligada. Saiba mais
Este tópico fornece o exemplo de código completo para um aplicativo básico da Plataforma Universal do Windows (UWP) em JavaScript e HTML que mostra um anúncio intersticial. Para obter instruções passo a passo que mostram como configurar o projeto para usar esse código, consulte Anúncios intersticiais. Para obter um projeto de exemplo completo, consulte os exemplos de publicidade no GitHub.
Exemplo de código
Esta seção mostra o conteúdo dos arquivos em HTML e JavaScript em um aplicativo básico que mostra um anúncio intersticial. Para usar esses exemplos, copie esse código para um projeto JavaScript Aplicativo WinJS (Universal do Windows) no Visual Studio.
Este aplicativo de exemplo usa dois botões para solicitar e, em seguida, iniciar um anúncio intersticial. Os arquivos main.js e index.html gerados pelo Visual Studio foram modificados e são mostrados abaixo. O arquivo script.js mostrado abaixo contém a maior parte do código no exemplo, e você deve adicionar esse arquivo à pasta js no projeto.
Substitua os valores das applicationId variáveis e adUnitId pelos valores dinâmicos do Partner Center antes de enviar seu aplicativo para a Loja. Para obter mais informações, consulte Configurar unidades publicitárias no app.
Observação
Para alterar este exemplo e mostrar um anúncio intersticial de banner em vez de um anúncio intersticial em vídeo, passe o valor InterstitialAdType.display para o primeiro parâmetro do método RequestAd em vez de InterstitialAdType.video. Para saber mais, consulte Anúncios intersticiais.
