Array zu Objekt hinzufügen

Question

Ich versuche, Json zweimal durchlaufen: einmal für Elternelemente und dann wieder für weitere Details. (Dies wird schließlich nach XML exportiert.) Wie gehe ich in der Zwischenzeit beim Hinzufügen eines Arrays zu einem Objekt vor? Meine aktuellen Code erstellt keine 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']; 
     }); 
    }); 

Answer 1

Nachdem Sie Ihre Anfrage in den Kommentaren zu klären, ist die Lösung einfach :

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

Ich brauche aber einige gravierende Mängel in Ihrem Code zu erwähnen:

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 completey incomprehensible 
    // 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 "" 
    }); 
});

Wenn Sie XMLObjectDetail tun, wie diese für XMLObject auf Array-Objekte hinzuzufügen:

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']; 
     }); 
    });
