How to get json key and value in javascript?

I am returning a json as shown below

{"name": "", "skills": "", "jobtitel": "Entwickler", "res_linkedin": "GwebSearch"}

I am trying to get each element key and value: 

..
}).done(function(data){
    alert(data['jobtitel']);
});

I am getting undefined in alert. WHY? I tried data.jobtitel, i tried loop but no success..

//By using jquery json parser    
var obj = $.parseJSON('{"name": "", "skills": "", "jobtitel": "Entwickler", "res_linkedin": "GwebSearch"}');
alert(obj['jobtitel']);

//By using javasript json parser
var t = JSON.parse('{"name": "", "skills": "", "jobtitel": "Entwickler", "res_linkedin": "GwebSearch"}');
alert(t['jobtitel'])

Check this jsfiddle

As of jQuery 3.0, $.parseJSON is deprecated. To parse JSON strings use the native JSON.parse method instead.

It looks like data not contains what you think it contains - check it.

let data={"name": "", "skills": "", "jobtitel": "Entwickler", "res_linkedin": "GwebSearch"};

console.log( data["jobtitel"] );
console.log( data.jobtitel );

For getting key

var a = {"a":"1","b":"2"};
var keys = []
for(var k in a){
  keys.push(k)
}

For getting value.

var a = {"a":"1","b":"2"};
var values = []
for(var k in a){
  values.push(a[k]);
}

You can use the following solution to get a JSON key and value in JavaScript:

var dt = JSON.stringify(data).replace('[', '').replace(']', '');
if (dt) {
  var result = jQuery.parseJSON(dt);
  var val = result.YOUR_OBJECT_NAME;
}

A simple approach instead of using JSON.parse

 success: function(response){
     var resdata = response;
     alert(resdata['name']);
}

var data = {"name": "", "skills": "", "jobtitel": "Entwickler", "res_linkedin": "GwebSearch"}

var parsedData = JSON.parse(data);
alert(parsedData.name);
alert(parsedData.skills);
alert(parsedData.jobtitel);
alert(parsedData.res_linkedin);

}).done(function(data){
    obj = JSON.parse(data);
    alert(obj.jobtitel);
});
