Question

Is it possible to make something like this:

var fieldObjArray = Array();;

    for(var k in SpesificPropertiesInfo){
        var fieldTable = createFieldTable(SpesificPropertiesInfo[k]);
        fieldObjArray[SpesificPropertiesInfo[k].fieldName]['fieldStatus'] = SpesificPropertiesInfo[k].fieldStatus;
        fieldObjArray[SpesificPropertiesInfo[k].fieldName]['fieldName'] = SpesificPropertiesInfo[k].fieldName;
        fieldObjArray[SpesificPropertiesInfo[k].fieldName]['columnName'] = SpesificPropertiesInfo[k].columnName;
    }

I want to create an array that it first dimensions is an associative one (and dynamic // i do not know its name at the beginning), the second dimensions is an associative but i do know it’s name.

Yes. It is.

However, use objects, not arrays.
Arrays in JS are only for 0...n indices, and don’t work properly with for ... in, either.

var myObj = {},

    key = "",
    val = "";

for (key in yourObj) {
    if (yourObj.hasOwnProperty(key)) {
        val = yourObj[key];
        myObj[val.fieldname] = {
            fieldStatus: val.fieldStatus,
            fieldName: val.fieldName,
            colName: val.colName
        };

        //...
    }
}

You now have a myObj which has all of yourObj‘s primary indices, each one an object, containing the properties of the second dimension…
