copied!<p><code>$.post</code> and <code>$.get</code> are just shorthand versions of the more structured <code>$.ajax()</code>, so I prefer using the latter. The additional structure keeps me straight.</p> <p>Since you are using jQuery anyway, I would re-structure your code like this:</p> <pre><code>$('#q1').click(function() { var test = "Hello there"; $.ajax(function() { type: "POST", url: 'ajax.php', data: 'ans=' +test+ '&anothervarname=' + anothervarvalue, success: function(recd_data) { alert('Rec'd from PHP: ' + recd_data ); } }); }); </code></pre> <p>Note that the <code>data:</code> line is for example purposes and does not match with your code -- just showing you how to pass variables over to the PHP side.</p> <p>Of course, the above includes removing the inline javascript -- never a good idea -- from your anchor tag HTML, thus:</p> <pre><code> <a href="#" id="q1" >click</a> </code></pre> <hr> <p>Also, on the PHP side, you can verify that things are working by adding a test at the top. Matching with the <code>data:</code> line in the example AJAX code, it would look like this:</p> <p><strong>ajax.php</strong></p> <pre><code><?php $a = $_POST['ans']; $b = $_POST['anothervarname']; $response = '<h1>Received at PHP side:</h1>'; $response .= 'Variable [ans] has value: ' . $a . '<br>'; $response .= 'Variable [anothervarname] has value: ' . $b . '<br>'; echo $response; </code></pre> <p>Important: Note the use of <code>echo</code>, not <code>return</code>, to send values back to the AJAX script.</p> <p>Also note that you <strong>must</strong> deal with the stuff returned from PHP <strong>in the AJAX <code>success:</code> function ONLY</strong>. If you need access to that data outside of the <code>success:</code> function, then you can stick the data into a hidden <code><input type="hidden" id="myHiddenInput"></code> element, like this:</p> <pre><code>success: function(recd_data) { $('#myHiddenInput').html(recd_data); } </code></pre> <hr> <p>Here are some additional examples of simple AJAX constructions:</p> <p><a href="https://stackoverflow.com/questions/13734395/form-inside-of-load-not-posting-correctly/13734466#13734466">A simple example</a></p> <p><a href="https://stackoverflow.com/questions/17887098/two-post-requests-one-after-the-other-second-post-request-doesnt-get-execut/17887642#17887642">More complicated example</a></p> <p><a href="https://stackoverflow.com/questions/16924082/dynamic-drop-down-box/16924652#16924652">Populate dropdown 2 based on selection in dropdown 1</a></p>
