How do I pass font names to webfont.load as a string

I am using basic font loading like this:

WebFont.load({
    google: {
        families: [ 'Droid Sans','Cookie','Parisienne' ]
    }
});

But I need to pass the font names to this as a string. Something like:

var fntstr = "'Droid Sans','Cookie','Parisienne'";
WebFont.load({
    google: {
        families: [ fntstr ]
    }
});

Why doesn't this work? Isn't that just a json structure being passed to Webfont.load?

Solution

In your first example, families is an array containing 3 strings.

['Droid Sans','Cookie','Parisienne']

In your second example, families is an array containing 1 string.

["'Droid Sans','Cookie','Parisienne'"]

To make this work, you want to do something like the following:

var fntstr = "'Droid Sans','Cookie','Parisienne'";
var fntarr = fntstr.split(',');
WebFont.load({
    google: {
        families: fntarr
    }
});

The split method will split your string at each comma and create an array with the elements.
