You don't have to wrap that in a function.
For example, use: (if you're using 1.2 or 1.2compat in 1.3, it might be
safer to use .pass, which is basically the same as .bind, but with swapped
arguments (first the arguments, and then the thisArg: fn.pass([arg1, arg2,
...], thisArg); This is because the behavior changed a little when using
arguments with .bind to make it EcmaScript 5 compatible.)
setInterval(this.BtnsScroll.bind(this, 'down'), 20);
Using .pass:
setInterval(this.BtnsScroll.pass('down', this), 20);
Also with wrapping the context (this) changes and calling bind doesn't
execute the function, so you might want to use .call or .apply (native js
methods)
setInterval(function(){
this.btnsScroll.call(this, 'down');
}.bind(this), 20);
