79:     end
onload_function()

Returns the Javascript code to initialize the SoundManager2 API via it‘s "soundManager.onload" function. Basically, this method is called by the initialize helper methods when creating a list of sounds to play later.

92:       @sounds.each do |sound|
93:         output += %Q{\tsoundManager.createSound("#{sound.id}", "#{sound.url}");\n}
94:       end
95:       
96:       output += "}"
97:     end
onload_function?()

Is there a need to create an onload_function Javascript definition?

83:       !@sounds.empty?
