Helen, Jobe - thanks for your replies!
Jobe: excellent, that comes very close and does help.
The only issue I had was that the for-in loop messes up the order of the
items in the Array. While for one-dimensional Arrays it's just reversed
and can be 'cured' easily by a call to Array.reverse(), with
multi-dimensional Arrays the order of the for-in loop is a non-intuitive
mess.
Taking your ideas and starting over I came up with this:
/*
Accepts a complex object and returns its String representation
Handy for saving complex data structures as Strings
The object may contain nested Variables of the following types:
Object, Array, String, Number, Boolean
Example:
o = {a:1, b:'Beta', c:{c1:["c1_0", "c1_1", "c1_2"], c2:true}};
var s:String = stringify(o);
trace(s);
// Output:
// {a:1, b:"Beta", c:{c1:["c1_0", "c1_1", "c1_2"], c2:true}}
*/
function stringify(o:Object):String {
s = arguments[1] ? s : '';
var isArray:Boolean = o instanceof Array ? true : false;
s += isArray ? '[' : '{';
if(isArray) {
for(var i=0, len=o.length; i<len; i++){
if(i){ s += ", "}
s+= (typeof o[i] == "object") ? stringify(o[i],
"") : (typeof(o[i]) == 'string' ? '"'+o[i]+'"' : o[i]);
}
}else{
var c = '';
for(var p in o){
s += c + p +":"+((typeof o[p] == "object") ?
stringify(o[p], "") : (typeof(o[p]) == 'string' ? '"'+o[p]+'"' : o[p]));
c = ", ";
}
}
s += isArray ? ']' : '}';
return s;
}
It's not much more readable though ;-)
Thanks again!

Hi Andreas,
Give this a shot I think it will do what you need. Its a little messy
since
I just typed it really quick. Hope it helps:
//---Some contrived complex structure to trace
var myOb = new Object();
myOb.name = "jobe"
myOb.animals = ["free", "gulliver"];
myOb.someArr = [{email:"[EMAIL PROTECTED]", vocation:"programmer",
male:true, hasKids:false}, 30];
//------
checkIt();
function checkIt() {
var output:String = inspect(myOb, "");
trace(output);
}
function inspect(ob, str, parent) {
if (ob instanceof Array) {
str += "[";
} else if (ob instanceof Object) {
str += "{";
}
var firstone:Boolean = true;
for (var i in ob) {
var type = typeof ob[i];
if (!firstone) {
str += ", ";
} else {
firstone = false;
}
if (type == "object") {
var val = inspect(ob[i], "", ob);
if (ob instanceof Array) {
str += val;
} else {
str += i+": "+val;
}
} else {
if (ob instanceof Array) {
str += interpretValue(ob[i])
} else if (ob instanceof Object) {
str += i+":"+interpretValue(ob[i]);
}
}
}
if (ob instanceof Array) {
str += "]";
} else if (ob instanceof Object) {
str += "}";
}
return str;
}
function interpretValue(val) {
if (Number(val) === val){
//number
return val;
} else if (val == true || val == false) {
return val;
} else {
return "'"+val+"'";
}
return val;
}
