3.3.1 Decode Events
The reader object defines an event onDecode. Section 4.3.2.3 discusses decode events.
Example:
var numDecodes = 0;
var numDecodesProcessed = 0;
reader.onDecodeAttempt = function(count)
{
numDecodes = count;
numDecodesProcessed = 0;
}
reader.onDecode = function(decode)
{
if( ++numDecodesProcessed < numDecodes )
{
// process individual decode, save in variables, etc.
}
else
{
// process the whole set, using saved variables, etc.
}
}
