Object.keys ?

[Lee Goddard]

Hi all

I'm stuck, please help.

This line:
console.info( self.options.rules );

Renders:
Object { F="F[-FF]F[+FF]F"}

The very next line:
console.info( Object.keys( self.options.rules ) );

Renders:
[]

Have I over-looked something?

TIA!
Lee

This is not enough information, please post a fiddle with all the
necessary code.

Okay, Matthew - what more should I add?

As I read it, the console shows the value of an Object with one key, but
Object.keys doesn't show the key. Does that sound right?

Object.keys only returns own properties, stuf in options are not own properties. If you really need the keys, you have to Object.clone it first.

Ah, thanks Matthew - getting a fiddle ready revealed I had forgotten a
line in the class definition:

this.setOptions(options);

Cheers
Lee

":" instead of "="
