In this article, we will learn about the getJSON() method in jQuery, along with understanding their implementation through the example. jQuery is an open-source JavaScript library that simplifies the interactions between an HTML/CSS document, It is widely famous for its philosophy of “Write less, do more".

The getJSON() method in jQuery fetches JSON-encoded data from the server using a GET HTTP request.

Syntax:

$(selector).getJSON(url,data,success(data,status,xhr))

Parameters: This method accepts three parameters as mentioned above and described below:

url: It is a required parameter. It is used to specify the URL in the form of a string to which the request is sent
data: It is an optional parameter that specifies data that will be sent to the server.
callback: It is also an optional parameter that runs when the request succeeds.

Return Value: It returns XMLHttpRequest object.

Please refer to the jQuery Tutorial and jQuery Examples articles for further details.

employee.json file:

{
"name": "Tony Stark",
"age" : "53",
"role": "Techincal content writer",
"company":"Geeks for Geeks"
}

Here, we get the JSON file and displays its content.

HTML

<!DOCTYPE html> <html>  <head>     <title>jQuery getJSON() Method</title>     <script src= "https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js">     </script>      <!-- Script to get JSON file and display its content -->     <script type="text/javascript" language="javascript">         $(document).ready(function () {             $("#fetch").click(function (event) {                 $.getJSON('employee.json', function (emp) {                     $('#display').html('<p> Name: ' + emp.name + '</p>');                     $('#display').append('<p>Age : ' + emp.age + '</p>');                     $('#display').append('<p> Role: ' + emp.role + '</p>');                     $('#display').append('<p> Company: '                         + emp.company                         + '</p>');                 });             });         });     </script> </head>  <body>      <p> Click on the button to fetch employee data </p>      <div id="display"           style="background-color:#39B54A;">     </div>     <input type="button"             id="fetch"             value="Fetch Employee Data" /> </body>  </html>
