Question

I have a typical javascript function with some parameters

my_function = function(content, options) { action }

if I call the function as such :

my_function (options)

the argument “options” is passed as “content”

how do i go around this so I can either have both arguments passed or just one ?
thank you

Answer 1

You have to decide as which parameter you want to treat a single argument. You cannot treat it as both, content and options.

I see two possibilities:

1. Either change the order of your arguments, i.e. function(options, content)

2. Check whether options is defined:

   function(content, options) {
       if(typeof options === "undefined") {
           options = content;
           content = null;
       }
       //action
   }
   

   But then you have to document properly, what happens if you only pass one argument to the function, as this is not immediately clear by looking at the signature.
