javascript - 如何在javascript中获取json键和值？

Question

我正在返回一个json，如下所示

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

我正在尝试获取每个元素的键和值:

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

我收到 undefined 警报。为什么？我试过 data.jobtitel，我试过循环但没有成功..

//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 usethe native JSON.parse method instead.
