Parse JSON in JavaScript to display a specific name/value pair?

Javascript Web Development Object Oriented Programming

To parse JSON, use parseJSON() and for displaying a specific pair, use the $.each() function.

Let’s say the following is our JSON, which is parsed −

const APIData =
'[{"Name":"John","Age":21},{"Name":"David","Age":24},{"Name":"Bob","Age" :20}]';
const getObject = jQuery.parseJSON(APIData);

Now, let’s see the complete code and fetch the “Name” pairs −

Example

Live Demo

<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initialscale=
1.0">
<title>Document</title>
</head>
<link rel="stylesheet"
href="//code.jquery.com/ui/1.12.1/themes/base/jquery-ui.css">
<script src="https://code.jquery.com/jquery-1.12.4.js"></script>
<script src="https://code.jquery.com/ui/1.12.1/jquery-ui.js"></script>
<body>
<script>
   const APIData =
   '[{"Name":"John","Age":21},{"Name":"David","Age":24},{"Name":"Bob","Age":20}]';
   const getObject = jQuery.parseJSON(APIData);
   $.each(getObject, function (k,obj) {
      console.log(obj['Name']);
   });
</script>
</body>
</html>

To run the above program, save the file name “anyName.html(index.html)” and right click on the file. Select the option “Open with Live Server” in VS Code editor.
