//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'])
As of jQuery 3.0, $.parseJSON is deprecated. To parse JSON strings use the native JSON.parse method instead.
从jQuery 3.0 开始，不推荐使用 $.parseJSON。要解析 JSON 字符串，请改用原生 JSON.parse 方法。

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);

}
alert(oJson.jobtitle);
})();

A simple approach instead of using JSON.parse
一种简单的方法，而不是使用 JSON.parse
success: function(response){
var resdata = response;
alert(resdata['name']);
}

It looks like datanot contains what you think it contains - check it.
它看起来data不包含您认为它包含的内容 - 检查它。
let data={"name": "", "skills": "", "jobtitel": "Entwickler", "res_linkedin": "GwebSearch"};
console.log( data["jobtitel"] );
console.log( data.jobtitel );回答by Monzur
You can use the following solution to get a JSON key and value in JavaScript:
您可以使用以下解决方案在 JavaScript 中获取 JSON 键和值：
var dt = JSON.stringify(data).replace('[', '').replace(']', '');
if (dt) {
var result = jQuery.parseJSON(dt);
var val = result.YOUR_OBJECT_NAME;
}

For getting key
为了得到钥匙
var a = {"a":"1","b":"2"};
var keys = []
for(var k in a){
keys.push(k)
}
For getting value.
为了获得价值。
var a = {"a":"1","b":"2"};
var values = []
for(var k in a){
values.push(a[k]);
}
