Remove key-value pair from JSON object

Question

I have this JSON object below;

[     {         XXX: "2",         YYY: "3",         ZZZ: "4"     },     {         XXX: "5",         YYY: "6",         ZZZ: "7"     },     {         XXX: "1",         YYY: "2",         ZZZ: "3"     } ] 

I want to remove the YYY key-value from the json object such that the new json object will look like this;

[     {         XXX: "2",                ZZZ: "4"     },     {         XXX: "5",                ZZZ: "7"     },     {         XXX: "1",                ZZZ: "3"     } ] 

I tried delete jsonObject['YYY'] but this is not correct. How can this be done in javascript? Thank you.

What you call your "JSON Object" is really a JSON Array of Objects. You have to iterate over each and delete each member individually:

for(var i = 0; i < jsonArr.length; i++) {     delete jsonArr[i]['YYY']; }
