Check [ ObjectUtil.toString

Here's another example:
public function rTrace(obj:*, tab:Number=0):void {
if(tab > 10) return;
for(var key:String in obj) {
if(typeof(obj[key]) == "object" || obj[key] is Array) {
tr(doTab(tab)+key+"["+typeof(obj[key])+"]= {");
rTrace(obj[key], tab+2);
tr(doTab(tab)+"}");
} else
tr(doTab(tab)+key+"["+typeof(obj[key])+"]="+obj[key]);
}
}
private function doTab(n:Number):String {
var out:String = "";
for(var i:Number=0; i<n; i++)
out += " ";
return out;
}
private function tr(msg:String):void {
trace(msg);
}
Usage example:
var test:Object = {id:"asdf", count:17,
childs:[1,2,7,39], tasks:{task_1:"test", task_2:true}};
rTrace(test);
Produces output:
tasks[object]= {
task_2[boolean]=true
task_1[string]=test
}
count[number]=17
childs[object]= {
0[number]=1
1[number]=2
2[number]=7
3[number]=39
}
id[string]=asdf
