    "yAxis":"ProductionCounts",
    "interestingMoments": []
}

I want to access the value of json object. Field name of json object will be different each time . In this sample json I am having 2 field "Part" and "ProductionCounts" but it may be something else next time when I am getting the json so I am sending the field name in xAxis and yAxis with json but when I am trying to access the jsonData.data[0].data[0].xAxis , it is giving me undefined instead of value. I can't access like jsonData.data[0].data[0].Part as field name will be different each time so I am trying to access it through variable .

Please let me know how can I access the json object field values without knowing the name of field or through variable.

if you store your response in

var jsonData = {//your response object};

you should acces for example your first item:

jsonData.data[0].data[0][jsonData.xAxis]

[manvinder]

First get the name of fields xAxis and yAxis first like this
var xAxisValue = jsonData.xAxis;
var xAxisValue = jsonData.yAxis


Than search for the value like this


var val1 = jsonData.data[0].data[index].xAxisValue;
var val2 = jsonData.data[0].data[index].yAxisValue;

I didn't tested this, but It should work.
