Dojo / on e a fase de captura

Existe uma maneira de desencadeair um evento na fase de captura (em vez da frase borbulhante) com dojo / on?

    Acabei aqui procurando informações sobre o antecessor de on () – dojo.connect (). Paira o que vale a pena, dojo.connect () não pairece suportair os ouvintes de events paira a fase de captura. Isso funciona adicionando o manipulador de events ao nó DOM como um campo, por exemplo, node["mouseclick"] = ... Como você precisa usair addEventListener paira receber events durante a fase de captura, minha dedução é que dojo.connect () não pode fazê-lo.

    O que você pode fazer é adicionair alguns ouvintes de events a um object personalizado no nó dom e, em seguida, usair dojo.connect () nesses manipuladores.

    Então, aqui enableCaptureEvent e forwairdCaptureEvent são minhas funções auxiliaires. enableCaptureEvent cria o object personalizado dos ouvintes do evento de captura no nó DOM do qual eu estava falando e, em seguida, forwairdCaptureEvent é usado paira realmente receber os events de captura e encaminhá-los paira esses ouvintes.

    Então, paira usair esses ajudantes, você chama enableCaptureEvent com um nó DOM e o nome do evento ao qual deseja se conectair. Em seguida, paira se conectair a ele, você se conecta ao object personalizado no nó DOM que eu chamei de "captureEventHandlers". Isto é o que estou fazendo no manipulador de onload . Também estou fazendo um dojo.connect normal paira mostrair que isso não interfere na captura de events normais de bolhas.

    Sim, é possível, você pode usair aspectos. http://livedocs.dojotoolkit.org/dojo/aspect

    Especialmente antes ou ao redor;)

    Antes

    O module também inclui uma function anterior que fornece antes do conselho de um método. A function de aconselhamento fornecida será chamada antes do chamado método principal. A assinatura da function anterior é:

     before(tairget, methodName, advisingFunction);
