adding array to Object
提问by MG1
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
我试图通过 Json 循环两次：一次用于父元素，然后再次用于更多细节。（这最终将导出到 XML） 同时，我如何将数组添加到对象？我当前的代码没有创建 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'];
});
});

After you clarified your request in the comments, the solution is easy:
在评论中澄清您的请求后，解决方案很简单：
var XMLObject = {};
var XMLObjectDetail = [];
XMLObject["XMLObjectDetail"] = XMLObjectDetail;
you may shorten it to
你可以把它缩短为
var XMLObjectDetail, XMLObject = {XMLObjectDetail: XMLObjectDetail = []};
However, I need to mention some serious flaws in your code:
但是，我需要提及您的代码中的一些严重缺陷：
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 ""
});
});

If you want to add objects for XMLObjectto array XMLObjectDetaildo like this:
如果要为XMLObject数组添加对象，XMLObjectDetail请执行以下操作：
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'];
});
});
