i beginner ajax world , trying call contents php page using $.ajax() function , code couldn't executed. html page used:

<!doctype html> <html> <head>     <title>ajax</title>     </head> <body>  <div >         <input type="text" name="search" id="search">            <br>     <br>     <h2 id="result"></h2> </div>     <script   src="https://code.jquery.com/jquery-2.2.4.min.js"   integrity="sha256-bbhdlvqf/xty9gja0dq3hiwqf8lacrtxxzkrutelt44="   crossorigin="anonymous"></script> <script src="js/script.js"></script> </body> </html>

the jquery code used in script.js:

$(document).ready(function() {      $('#search').keyup(function () {         var search = $('#search').val();          $.ajax({              url:'search.php',             //the page request go              data:{search: search},              type: 'post',             success:function(data) {                 if(!data.error){                     $('#result').html(data);//the h2 want echo uing ajax                 }             }          });      });  });

the search.php page contain:

$search = $_post['search']; echo $search;

the code not executed. should do.

i see issue in response php code , in ajax side success code.

you not sending in response json format data.error meaningless. in success callback code should this.

success:function(data) {     $('#result').html(data);//the h2 want echo uing ajax }
