Whenever you need to pass a variable number of arguments, check Function.apply().It generally will be the answer to your problem!
If I understood your problem correctly, this should do what you want: var args:Array = [0,1,2,3,4,5]; var jsFunctionName:String = "someJsFunction"; var parameters:Array = args && args.length > 0 ? [jsFunctionName].concat(args) : [jsFunctionName]; ExternalInterface.call.apply(null,parameters); Since ExternalInterace::call is static, the first param (the "this" context object) is null. The parameters are passed to the function as if you had written them in source code like func(param1,param2,param3), etc, as opposed to func(paramsArray). Now, this works because ExternalInterface::call expects the first param to be the name of function to be called and a variable (and optional) list of parameters. So, you just have to build an array that contains in its first position the function name and after that the rest of the args you want to pass. In this example, this is equivalent to this code: ExternalInterface.call(jsFunctionName,0,1,2,3,4,5); Cheers Juan Pablo Califano 2010/6/6 Ashim D'Silva <[email protected]> > The last 2 weeks were crazy and I completely lost track of this so I > apologise for not responding to the answers (cheers though!).
