使用JQuery Ajax保存数据以避免页面重新加载

At the moment I save data when changes are made on the page using ordinary PHP but of course it makes the page reload every time which resets everything. I really need to do it without page reload. I've heard its possible to do with Ajax and JQuery. I would much prefer Jquery answers rather than Javascript.

    for example you have this form

    <input type="text" name="name" class="abc" id="test" placeholder="Name">
    <a href="#" class="PopUpSendBtn" id="sendinfo">Send</a>

    then write Script

        $(document).ready(function() {
       // invoke event on clicking send button
       $("#sendinfo").on("click", function(evt) {
       // get value of input field
    var userName = $('#test').val();
                    url: filename.php,
                    async: false,
                    success: function(output_string){
                        //    alert(output_string);
                        if(output_string == 1){
                            // do someting
                        } else { 
                            // do someting
                       , error: function(object, status, response) {

    your php file(filename.php) get data using post request

     $data = $_POST['userName'];
    // query to store data in db
    // after saving data successfully in db your can send back a success message //in json or any other format (in my case i am using json)
             $data['success'] = TRUE;
            echo json_encode($data);

    Don't forget to include jquery script.

    This is the basic idea how to send data using ajax. You can modify it according to your requirements.
