Title says it all I have the following function :
var foo = function(arg1, arg2,arg3) {
// code
}
I want to do something like :
foo('bar', (x == true ? arg2, arg3 : arg2,arg3))
But I get hit with SyntaxError: Unexpected token , what is the right syntax to do something like this?
I would go with readability as JCOC611 said...
Yet, the "right" way is using .apply():
foo.apply(this, (x == true ? [arg1, arg2, arg3] : [arg1 ,arg2, arg3]))
I don't think it is worth it to save a few characters. It's much more valuable to have readable code. Just get a minifier/uglyfier, and do this:
if(x === true){
foo('bar', arg2, arg3);
}else{
foo('bar', arg2, arg3);
}
var foo = function(arg1, arg2,arg3) {
console.log(arguments)
}
var x = false;
var args = [];
args.push('bar');
x == true ? (function(){args.push('arg2'); args.push('arg3')})() : args.push('arg2');
console.log(args)
foo.apply(this,args)
There are two methods to pass the variable no of arguments to the function.
Use either one as per your need.
