jQuery AJAX POST Send Variable

I have the following code:

  var result = confirm("You want to Subscribe to our Newsletter?");
  var emailAddress = $("#subscribeEmail").val();

  if (result == true) {

    $.ajax({
      type: 'POST',
      url: '/php/subscribeNewsletter.php',
      data: '{"email": "' + emailAddress + '"}',
      complete: function(r){
    alert(r.responseText);
    }

    });


  }

I believe the problem is to do with: data: '{"email": "' + emailAddress + '"}',

I am receiving an empty $_POST array on the server side of things.

Better pass data to a variable and use it while sending,

 var temp = 'email:' + emailAddress;
 ...
 data: temp;
 .....

You can use like below

$.get('/Presentation/AjaxData/History.aspx', { itemID: itemid }, function (data) {
        $('.history-listing-tabs>.tab-item').html(data);
});

provide the data attribute in the ajax call as a json object instead of string.

like

data: {"email": emailAddress },

Pass an object literal, not a string:

data: {email: emailAddress },

jQuery will transform the object into the URL encoded key/value pairs, which will be picked up in the $_POST array on the PHP side.

Your current code is actually sending a JSON string as the raw POST data. jQuery is seeing the data type is a string, and so it doesn't do any processing, so you'd have to access the raw POST data on the PHP side and do a JSON decode to get it.

...
data: {"email": emailAddress},
