ActionScript 3 Object to name value string

In a Flex application I am trying to turn an Object into a QueryString such as name1=value1&name2=value2... But I am having trouble getting the names of the Objects children. How do I enumerate the names instead of the values?

Thanks

From stackoverflow

• I'm guessing you're doing a for each(in) loop. Just do a normal for(in) loop and you'll get the names instead of the values:

  for(var name:String in obj) {
    var value:* = obj[name];
    // do whatever you need
  }
  

  Sophistifunk : If it's a concrete class instead of just an Object, see ObjectUtil.getClassInfo()

  Herms : I believe `for(in)` still works on concrete classes, but it's generally more limited on what it returns. It will only pick up what those classes have set up as visible using the `setPropertyIsEnumerable` method.

• Ok, first off, if you need that query string to actually query a server, you don't really need to get it yourself as this code will query the server for you

  protected function callSerivce():void
  {
      var o:Object = new Object();
      o.action = "loadBogusData";
      o.val1 = "dsadasd";
      service.send(o);
  }
  
  <mx:HTTPService id="service" url="http://www.somewhere.com/file.php" method="GET" showBusyCursor="true"/>
  

  Will make a call to the server like this: http://www.somewhere.com/file.php?action=loadBogusData&val1=dsadasd

  But in case you really want to analyze the object by hand, try using ObjectUtil.getClassInfo, it returns a lot of information including all the fields (read more on LiveDocs).
