Steps to do this task:
#1: Make HTML form from where we will make server request.
#2: Make use of javascript to link with library file of server
#3: Handle the Client request
#4: Send response of Client Request

First we make html form ,
===============
We have added some data fields

Make use of javascript ‘post’ method
===============
// other ajax request
jQuery(“#frmPostOtherPage”).validate({
submitHandler:function(){
var post_data = jQuery(“#frmPostOtherPage”).serialize()+”&action=c&param=form_data”;
jQuery.post(ajaxurl,post_data,function( response){
var data = jQuery.parseJSON(response);
console.log(“Name: “+data.txtName+” and Email: “+data.txtEmail);
});
}
});
// By using this we serialzed form data ‘jQuery(“#frmPostOtherPage”).serialize()’ and now we are almost ready to send
data to server
‘ajaxurl’: This is the value ‘admin-ajax.php’ by admin_url(‘admin-ajax.php’);

Parameter Details:
==========================
action=custom_ajax_req
// It attaches the library file with client request

if(isset($_REQUEST[‘action’])){ // it checks the action param is set or not

switch($_REQUEST[‘action’]){ // if set pass to switch method to match case
case “custom_ajax_req” :

add_action(“admin_init”,”add_custom_plugin_library”); // match case
function add_custom_plugin_library(){ // function attached with the action hook
global $wpdb;
include_once PLUGIN_DIR_PATH.”/library/custom-plugin-lib.php”; // ajax handler file within /library folder
// and now from this file we are going to handle ‘form_data’ variable data
}

break;

}
}

&param=get_message
// It find the executable function with this value’get_message’.

if(!empty($getParam)){
if($getParam==”form_data”){
// here we access form data.
}
}

// library file to use validate() method:
https://cdnjs.cloudflare.com/ajax/libs/jquery-validate/1.16.0/jquery.validate.min.js
