Reset to default 3You could send your data using .serialize() method.
$(function() {
$('input[name="button1"]').click(function() {
$.post(your_url, $(this).closest('form').serialize(), function(data) {
console.log(data);
});
});
});
It is the same effect with using an object as data:
$(function() {
$('input[name="button1"]').click(function() {
var data = {
username: $('#username').val(),
password: $('#password').val(),
};
$.post(your_url, data, function(data) {
console.log(data);
});
});
});
$( "form" ).submit(function( event ) {
console.log( $( this ).serializeArray() );
// do submit part here
});
As memory serves you can only send data back to the server via POST or GET using javascript. You would probably have to serialize the JSON before sending.
see https://stackoverflow./a/912247/1318677 for an example on how to serialize a JSON object.
Assuming you have JSON2 and Jquery included, The code may look like this
// create a listener on the submit event
$('form').on('submit', function (e) {
e.preventDefault();
// gets the data that will be submitted
var data = $(this).serializeArray(),
// the ajax url
url = './request/url';
$.ajax({
url: url,
type: 'POST',
contentType:'application/json',
data: JSON.stringify(data), //stringify
dataType:'json',
plete : function () {
// do what you want here
}
});
return false;
});
Be aware, untested script. Also make sure DOM exists before calling the script above. Which can be achieved by adding your scripts just before the </body> closing tag or use $(document).ready(/*script here*/);
use this one
add id button1
html
<form action="Login" method="post" name="MY Form">
userid<input id="username" name="username" type="text" /><br />
password<input id="password" name="password" type="password" /><br />
<input id="button1" name="button1" type="submit" value="login" />
</form>
javascript
$("#button1").click(function() {
formData = {
username: username,
password: password
}
$.ajax({
type: 'POST',
contentType: 'application/json',
url: "http://localhost/login.php",
dataType: "json",
data: formData,
success: function(data) {
console.log(data);
//success handler
},
error: function(data) {
//error handler
}
});
});
php
<?php
/*
* Following code will get single product details
* A product is identified by product id (pid)
*/
// array for JSON response
$response = array();
// include db connect class
require_once __DIR__ . '/db_connect.php';
// connecting to db
$db = new DB_CONNECT();
// check for post data
if (isset($_POST["username"]) && isset($_POST["password"])) {
$username = $_GET['username'];
$password = $_GET['password'];
// get a product from products table
$result = mysql_query("SELECT *FROM users WHERE username = '$username' AND password = '$password' ");
if (!empty($result)) {
// check for empty result
if (mysql_num_rows($result) > 0) {
$result = mysql_fetch_array($result);
$user = array();
$user["userId"] = $result["userId"];
$user["name"] = $result["name"];
// success
$response["success"] = 1;
// user node
$response["user"] = array();
array_push($response["user"], $user);
// echoing JSON response
echo json_encode($response);
} else {
// no product found
$response["success"] = 0;
$response["message"] = "No user found";
// echo no users JSON
echo json_encode($response);
}
} else {
// no product found
$response["success"] = 0;
$response["message"] = "No user found";
// echo no users JSON
echo json_encode($response);
}
} else {
// required field is missing
$response["success"] = 0;
$response["message"] = "Required field(s) is missing";
// echoing JSON response
echo json_encode($response);
}
?>
