I have following JSON:

  [ {
    "id":1,
    "firstName":"Markus",
    "lastName":"Maier",
    "email":"[email protected]",
    "externalId":"mmaie",
    "pany":"Intel"
    },
    {
    "id":2,
    "firstName":"Birgit",
    "lastName":"Bauer",
    "email":"[email protected]",
    "externalId":"bbaue"
    } ]

I want to iterate through both objects and get the value of the "email" key.. what is the simplest way to do that? Thanks!

• 1 This isn't even valid javascript. A object can't have values without keys (the inner objects). Should the outer braces be array braces? – Michael Ritter Commented Jan 23, 2017 at 12:59
• What have you tried? What are expected results? This isn't a free code writing service and you are expected to have done some research and show your attempts – charlietfl Commented Jan 23, 2017 at 13:01
• @ Michael Yes they should, i'm sorry! Edited now.. @charlietfl I'm very new to coding and i don't really have an idea where to start – MarkusFsx Commented Jan 23, 2017 at 13:03
• Start by studying some tutorials then – charlietfl Commented Jan 23, 2017 at 13:04
• @MarkusFsx see the code below. – Ataur Rahman Munna Commented Jan 23, 2017 at 13:05

If you want to end up with an array of just the emails, you may want to look into the .map() function.

var data = [{
  "id": 1,
  "firstName": "Markus",
  "lastName": "Maier",
  "email": "[email protected]",
  "externalId": "mmaie",
  "pany": "Intel"
}, {
  "id": 2,
  "firstName": "Birgit",
  "lastName": "Bauer",
  "email": "[email protected]",
  "externalId": "bbaue"
}];

var emails = data.map(d => d.email);

console.log(emails);

Follow the code.loop through the data each object and for each object get the desired value by key.

var data = [ {
    "id":1,
    "firstName":"Markus",
    "lastName":"Maier",
    "email":"[email protected]",
    "externalId":"mmaie",
    "pany":"Intel"
    },
    {
    "id":2,
    "firstName":"Birgit",
    "lastName":"Bauer",
    "email":"[email protected]",
    "externalId":"bbaue"
    } ];
    
    for(var i=0; i< data.length;i++){
        console.log(data[i]['email']);
    }
