How to create object properties from a JS string

Question

I have the following object

reportData: {}

and the following loop :

    for (var key in ABC.PrintReport.keyList) {
        console.log(ABC.PrintReport.keyList[key].Report_Key);
    }

This loop will print out :

objProperty0
objProperty1
objProperty2
objProperty3

I want to create properties for the object reportData that are named after each ABC.PrintReport.keyList[key].Report_Key.

reportData.objProperty0
reportData.objProperty1
reportData.objProperty2
reportData.objProperty3

Answer 1

You can use square brackets to create properties on objects in JavaScript:

for (var key in ABC.PrintReport.keyList) {
    var k = ABC.PrintReport.keyList[key].Report_Key;
    reportData[k] = 'some value';
}

Answer 2

for (var key in ABC.PrintReport.keyList) {
    reportData[ABC.PrintReport.keyList[key].Report_Key] = ABC.PrintReport.keyList[key].Report_Key;
}

Answer 3

Something like this should do it (see docs on bracket notation for object property access):

var reportData = {};
for (var key in ABC.PrintReport.keyList) {
    key = ABC.PrintReport.keyList[key].Report_Key;
    reportData[key] = 'some value';
}
