var result=[{"controlID":"B","currentValue":"5","onChange":"Testing(A,B)","onClick":""}];

How to I get the result Testing(A,B) based on OnChange Key.

Answer 1

As your variable result is an array you can access value using index.

var data = result[0].onChange;

 var result=[{"controlID":"B","currentValue":"5","onChange":"Testing(A,B)","onClick":""}]; var data = result[0].onChange; alert(data)
