EDT 0.8.1

I have a wav file that I'd like to play in my RUI client application when a certain event occurs.

How do you play wav files?

Richard,

EDT does not provide any default support for playing sound files within a Rich UI application.

I found the following link on the general topic of using sound in an HTML application, which might be useful - http://www.w3schools.com/html/html_sounds.asp

If you find an approach that suits your needs, you should be able to write an External Type to add this support to your EGL application.

Brian,

Thanks for the pointer. That gave me the start I needed and it was actually easier to get something working than I was expecting.

Within my event function I instantiated a html widget as follows and this played my wav file, which I'd previously imported into my webcontent/audio folder.

playme HTML{ text="<audio src=\"audio\\intro.wav\" autoplay preload=\"auto\" autobuffer></audio>" };

There's still some more work to do though as this works fine in chrome but not in firefox and I need to test the browser support for different audio capabilities and formats. I'll also need to make sure I destroy my instantiated widget.

There's some interesting stuff here that I'll start working through.

It looks like it's time to learn javascript.
