I am trying to loop through Json twice: once for parent elements and then again for more detail. (This eventually will be exported to XML) In the meantime, how do I go about adding an array to an Object? My current code doesn't create XMLObjectDetail

 XMLObject = {};
 var XMLObjectDetail = [];

 $.each(data, function(index, element) {
        XMLObject.CardCode = element['CardCode'] 
        XMLObject.CardName = element['CardName'];
        console.log(XMLObject);

  $.each(element, function(key, value) { 
       XMLObject[[XMLObjectDetail.InvPayAmnt]] = value['InvPayAmnt']; 
      });
  });

• javascript
• json

• Do you want to add the object to the array or the other way round? – Bergi Commented May 31, 2012 at 18:13
• I would like to add the array XMLObjectDetail to the object XMLObject. – MG1 Commented May 31, 2012 at 18:18
• Which property name should it get in the XMLObject? – Bergi Commented May 31, 2012 at 19:54

After you clarified your request in the ments, the solution is easy:

var XMLObject = {};
var XMLObjectDetail = [];
XMLObject["XMLObjectDetail"] = XMLObjectDetail;

you may shorten it to

var XMLObjectDetail, XMLObject = {XMLObjectDetail: XMLObjectDetail = []};

However, I need to mention some serious flaws in your code:

XMLObject = {}; // no var keyword: the variable will be global
var XMLObjectDetail = [];

$.each(data, function(index, element) {
    // I don't know how your data object/array looks like, but your code will be 
    // executed many times
    // For each element, you will overwrite the properties
    XMLObject.CardCode = element['CardCode'] // missing semicolon
    XMLObject.CardName = element['CardName'];
    // so that the final XMLObject will only contain cardcode and -name of the last one
    // It will depend on your console whether you see different objects
    // or the same object reference all the time
    console.log(XMLObject);

    // This part is pletey inprehensible
    // you now loop over the properties of the current element, e.g. CardCode
    $.each(element, function(key, value) { 
        // and again you only overwrite the same property all the time
        XMLObject[[XMLObjectDetail.InvPayAmnt]] = value['InvPayAmnt'];
        // but wait: The property name you try to set is very, um, interesting.
        // first, XMLObjectDetail is still an (empty) Array and has 
        //  no 'InvPayAmnt' property - leads to a undefined
        // then, you build an Array with that [undefined] value as the only item
        // OMG, an array? JavaScript does only allow strings as property names,
        //  so the array will be converted to a string - resulting to the empty string ""
    });
});

If you want to add objects for XMLObject to array XMLObjectDetail do like this:

var XMLObject, XMLObjectDetail = [];

 $.each(data, function(index, element) {
        XMLObject=new Object(); //or XMLObject = {};
        XMLObject.CardCode = element['CardCode'] 
        XMLObject.CardName = element['CardName'];
        console.log(XMLObject);

        XMLObjectDetail.push(XMLObject);//ADDED OBJECT TO ARRAY

      //DON'T KNOW WHAT ARE YOU TRYING TO DO HERE?
      $.each(element, function(key, value) { 
           XMLObjectDetail[[XMLObjectDetail.InvPayAmnt]] = value['InvPayAmnt']; 
      });
  });
