The original ‘distract or confuse’ meaning seems to have gone somewhat out of use. I has come across it before researching the phrase to write this piece.
The expression was then always in the form of ‘give someone the razzle-dazzle’, that is, confuse them. The earliest use that I can find of that sense of ‘razzle-dazzle’ is the US newspaper The Saint Paul Globe, April 1885:
Sir: As you seem to be in earnest in your efforts to give someone the dazzle-dazzle…
The expression very quickly came to be used with a more positive intent, that is, where ‘razzle-dazzle’ was considered to be indicate enjoyment rather than deception. That’s found in the Pennsylvania newspaper The Daily Republican, June 1887:
A meeting at City Hall resolved to celebrate the Fourth [of July] by a general old-time razzle-dazzle.

I can’t think of a better picture to portray razzle-dazzle than the flamboyant, energetic ball of excitement that was Little Richard.
