jQuery Ajax Post Data Example


Fugo Of FormGet

jQuery $.post() method is used to request data from a webpage and to display the returned result (sent from requested page) on to that webpage from where the request has been sent without page refresh.

$.post() method sends request along with some data using an HTTP POST request.

Under this, a request is send to a webpage (here it is jquery_post.php) from another page (say jquery_send.php) using syntax :

Syntax:

$.post( URL, data, callback);

Parameters:

  • URL

The URL parameter is defined for the URL of requested page which may communicate with database to return results.

$.post("jquery_post.php",data,callback);
  • data

The data parameter is defined to send some data along with the request.

,{   // Data Sending With Request To Server

name:vname,

email:vemail

}
  • callback

The callback parameter is defined for a function to be executed if the request gets succeeded. This contains two sub parameters , the first one holds the returned data from the requested page and  second one holds the status of the request.

,function(response,status){ // Required Callback Function

//"response" receives - whatever written in echo of above PHP script.

alert("*----Received Data----*\n\nResponse : " + response+"\n\nStatus : " + status);

}
Note : Both ‘ data ‘ and  ‘ callback ‘ parameters are optional parameters, whereas URL is mandatory for $.post() method.

Example:

The following example uses the $.post() method to send some data along with the request.

This is jquery_send.php page that contains jQuery $.post() method which can be implemented as given below:

<html>

<head>

<link href='http://fonts.googleapis.com/css?family=Source+Sans+Pro|Open+Sans+Condensed:300|Raleway' rel='stylesheet' type='text/css'>

<!-- Include JS File Here -->

<link href="style.css" rel="stylesheet"/>

<!-- Include JS File Here -->

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>

<script>

$(document).ready(function(){

$("#btn").click(function(){

var vname = $("#name").val();

var vemail = $("#email").val();

if(vname=='' && vemail=='')

{

alert("Please fill out the form");

}

else if(vname=='' && vemail!==''){alert('Name field is required')}

else if(vemail=='' && vname!==''){alert('Email field is required')}

else{

$.post("jquery_post.php", //Required URL of the page on server

{ // Data Sending With Request To Server

name:vname,

email:vemail

},

function(response,status){ // Required Callback Function

alert("*----Received Data----*\n\nResponse : " + response+"\n\nStatus : " + status);//"response" receives - whatever written in echo of above PHP script.

$("#form")[0].reset();

});

}

});

});

</script>

</head>

<body>

<div id="main">

<h2>jQuery Ajax $.post() Method</h2>

<hr>

<form id="form" method="post">

<div id="namediv"><label>Name</label>

<input type="text" name="name" id="name" placeholder="Name"/><br></div>

<div id="emaildiv"><label>Email</label>

<input type="text" name="email" id="email" placeholder="Email"/></div>

</form>

<button id="btn">Send Data</button>

</div>

</body>

</html>

And here we have “jquery_post.php” file , which contains following PHP codes, that reads the request, processes it  and return the result.

<?php

if($_POST["name"])

{

$name = $_POST["name"];

$email = $_POST["email"];

// Here, you can also perform some database query operations with above values.

echo "Welcome ". $name ."!"; // Success Message

}

?>
