Make an Array be proper English?

[handycam]

Here's my problem: I have a bunch of arrays ranging from 2 to 8 members. They look, of course, like this:

"red,green,blue"

but I need to wind up with a string of :

"red, green, and blue"

with a space after each comma and an "and" before the last member.

Anyone have a good idea on how to do this programmatically, in a was that I could process any such array from 2 up to 8-10 members? I'm figuring some sort of loop, but my earliest attempts can get complex and I'm looking for simple.

Thanks.

Insert " and " in the last element (off a copy of the array if necessary) and use the array toString function.

this is a quick method of doing what you want. This could probably be better written.

var arr:Array = new Array( "one", "two", "three", "four", "five", "six", "seven", "eight", "nine", "ten");

function arrToEnglishString( arr:Array ):String
{
    var txt:String = arr.join( ", " );
    var bgn:String = txt.substring( txt.lastIndexOf( ", " ), 0 );
    var end:String = txt.substr( txt.lastIndexOf( ", " ) + 2 );
    return( bgn += ", and " + end );
}

trace( arrToEnglishString( arr ) );

return arr.slice(0, -1).join(", ") + ", and "+arr[arr.length-1];

should do it

yep, that would do it. nice.
