I have one collection of json objects as follows.

[
  {"FirstName":"Test1","LastName":"User","Email":"[email protected]","City":"ahmedabad","State":"sk","Country":"canada","Status":"False","iUserID":"23"},
  {"FirstName":"user","LastName":"user","Email":"[email protected]","City":"ahmedabad","State":"Gujarat","Country":"India","Status":"True","iUserID":"41"},
  {"FirstName":"Ropbert","LastName":"Jones","Email":"[email protected]","City":"NewYork","State":"gfg","Country":"fgdfgdfg","Status":"True","iUserID":"48"},
  {"FirstName":"hitesh","LastName":"prajapti","Email":"[email protected]","City":"","State":"","Country":"","Status":"True","iUserID":"78"}

You can use delete operator and Array.prototype.forEach like this

objects.forEach(function(currentItem) {
    delete currentItem["Email"];
});

OP doesn't want to use a loop :) – Andy Mar 20 '14 at 10:29
@Andy, OP may not even want to see the word "for" in the code :) – lshettyl Mar 20 '14 at 10:41

You can use a regular expression to remove the properties from the JSON string:

s = s.replace(/,"Email":"(\\"|[^"])*","City":"(\\"[^"])*"/, '');
