Using readyState to indicate sound is loaded?

callhandler · Jul 15, 2003

I have a page that needs to pre-load several sounds before enabling some controls.

I add the sounds as such:
<EMBED NAME='sound1' SRC='sound1.wav' AUSTOSTART='FALSE' HIDDEN='TRUE'>

Then I use the boolean test

(document.all["sound1"].readyState=='complete')

to see if the sound is loaded.

Unfortunately, all the boolean test returns 'complete' even if the sound file is NOT loaded.

Any ideas how to fix this problem?

readyState has 3 different properties (0, 1, 4),

0 Contol un-initialized and not ready for use

1 Control is loading

4 Contol loaded and is ready for use

You could try something like this

if (myControl.readyState == 0)
{
//some code here
}

Hope this helps you out.

Unfortunately, the problem is not so simple...

myControl.readyState actually returns 'complete' when the sound has not loaded. THis is because the <EMBED> tag does not support readyState in the same way <IMG> does (found this on Microsoft's developers reference site).

I am investigating using something like this to handle the job --- I don't understand it entirely .....

<HTML XMLNS:MSIE >
<MSIE

OWNLOAD ID="oDownload" STYLE="behavior:url#default#download)" />

<SCRIPT>
function onDownloadDone() { alert ('Downloaded'); }
oDownload.startDownload('Quickbooks_2002.exe', onDownloadDone);
</script>

... but it looks like it will work!
