How to use POST method to send data in jQuery Ajax?

jQueryWeb DevelopmentFront End Technology

The jQuery.post( url, [data], [callback], [type] ) method loads a page from the server using a POST 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 or the return value of the .serialize() function that will be sent to the server.
  • callback − This optional parameter represents a function to be executed whenever the data is loaded successfully.
  • type − This optional parameter represents a type of data to be returned to callback function: "xml", "html", "script", "json", "jsonp", or "text".

Let’s say we have the following PHP content in result.php file:

<?php
if( $_REQUEST["name"] ) {

   $name = $_REQUEST['name'];
   echo "Welcome ". $name;
}
?>

Here's the code snippet to implement how to use POST method to send data in jQuery Ajax:

   <head>
      <script src = "https://ajax.googleapis.com/ajax/libs/jquery/2.1.3/jquery.min.js"></script>
       
      <script>
         $(document).ready(function() {
           
            $("#driver").click(function(event){
               
               $.post(
                  "result.php",
                  { name: "John" },
                  function(data) {
                     $('#stage').html(data);
                  }
               );            
            });
         });
      </script>
   </head>
   
   <body>
   
      <p>Click on the button to load result.html file −</p>
       
      <div id = "stage" style = "background-color:cc0;">
         STAGE
      </div>
       
      <input type = "button" id = "driver" value = "Load Data" />
       
   </body>
