How to retrieve data from JSON file using jQuery and Ajax?

JSONjQueryAjax

To retrieve data from JSON file using jQuery and Ajax, use the jQuery.getJSON( url, [data], [callback] )
The jQuery.getJSON( url, [data], [callback] ) method loads JSON data from the server using a GET HTTP request.

Here is the description of all the parameters used by this method −

  • url − A string containing the URL to which the request is sent
  • data − This optional parameter represents key/value pairs that will be sent to the server.
  • callback − This optional parameter represents a function to be executed whenever the data is loaded successfully.

Let’s say we have the following JSON content in result.json file −

{
"name": "John",
"age" : "30",
"sex": "male"
}

The following is the code snippet showing the usage of this method −

  <head>
      <title>The jQuery Example</title>
      <script src = "https://ajax.googleapis.com/ajax/libs/jquery/2.1.3/jquery.min.js"></script>
       
      <script>
         $(document).ready(function() {
           
            $("#driver").click(function(event){
               $.getJSON('result.json', function(jd) {
                  $('#stage').html('<p> Name: ' + jd.name + '</p>');
                  $('#stage').append('<p>Age : ' + jd.age+ '</p>');
                  $('#stage').append('<p> Sex: ' + jd.sex+ '</p>');
               });
            });
               
         });
      </script>
   </head>
