 'Ethnicity' : 'Declined' ,
 'Race' : 'OtherRace' , }

I need to access the 'Race' here.. how can i do it... Its an array which holds this data...

Answer 1

Thats not an array, its an object. You want to do something like:

var myObject = {
  'DateOfBirth' : '06/11/1978',
  'Phone' : '770-786',
  'Email' : '[email protected]' ,
  'Ethnicity' : 'Declined' ,
  'Race' : 'OtherRace'
};

// To get the value:
var race = myObject.Race;

If the Objects are inside an array var ArrayValues = [{object}, {object}, ...]; then regular array accessors will work:

var raceName = ArrayValues[0].Race;

Or, if you want to loop over the values:

for (var i = 0; i < ArrayValues.length; i++) {
    var raceName = ArrayValues[i].Race;
}
