this might help you , i dont think there is a more straight forward way than this.

var num = "zero one two three four five six seven eight nine ten eleven twelve thirteen fourteen fifteen sixteen seventeen eighteen nineteen".split(" ");
var tens = "twenty thirty forty fifty sixty seventy eighty ninety".split(" ");

function number2words(n){
    if (n < 20) return num[n];
    var digit = n;
    if (n < 100) return tens[~~(n/10)-2]   (digit? "-"   num[digit]: "");
    if (n < 1000) return num[~~(n/100)]  " hundred"   (n0 == 0? "": " and "   number2words(n0));
    return number2words(~~(n/1000))   " thousand"   (n00 != 0? " "   number2words(n00): "");
}
