I have simple code with html, JavaScript and PHP. I am trying to pass a variable from HTML to PHP through ajax.

A text box appears on screen with button, user inputs in the text field and clicks the button. The field text should appear before the field. But in my case, nothing happens when clicking the button. I am posting my code below. These are the three files I have made:


<!doctype html> 
<html lang="en">
      <input id="name" type="text" /> <input id="button" type="button" value="Load" /> 
      <div id="content"></div>
      <script type="text/javascript" src="ajax.js"></script> 


$('#button').click(function() {
    document.write("this is javascript");
    var name = $('#name').val();
        url: 'page.php',
        data: name,
        success: function(data) {


    if(isset($_GET['name'])) {
        echo "lllllllllllllllll";
        echo $name=$_GET['name'];

    Add CDN as mentioned above. Also make sure you load the jquery CDN or jquery.lib.js before including external js file, ajax.js in index.html.

    There is an issue in your $.ajax code:

    $.ajax({ url: 'page.php', data: name, success: function(data) { $('#content').html(data); } }); change this to:

    $.ajax( { type:'GET', url: 'page.php', data:"name=test" }, success: function(data) { $('#content').html(data); } );

    <script type="text/javascript" src="https://code.jquery.com/jquery-3.3.1.min.js"></script>

    add this in your javascript ajax: type : 'GET'. In your php code :

    echo $name;
