Post back variable from PHP to JS after POST?

Is it possible to post from a PHP file to a JS to a PHP and get the results from the external PHP file to the JS file that posted the information? I don't what to get back that it's a success - I want to get what's echoed from the actual content from the PHP file that processes it.

Here's the code that I have:

$(function() {
$(".deletebutton").click(function() {

$.ajax({
  type: "POST",
  url: "*****/process_delete.php",
  data: dataString,
  success: function() {
      // Get results from form here
  }
 });
return false;
});
});

Haven't found anywhere where this is possible, is it? If s开发者_StackOverflowo, please post some example code!

Thanks!

The success function receives the data that the server returned as its first parameter

$.ajax({
  type: "POST",
  url: "*****/process_delete.php",
  data: dataString,
  success: function(data) {
      // do something with data here
  }
 });

You can use the dataType attribute of your $.ajax object to ensure you get the data back in the format you expect. So if process_delete.php is returning JSON, for example:

$.ajax({
  type: "POST",
  url: "*****/process_delete.php",
  data: dataString,
  success: function(data) {
      // do something with data here
  },
  dataType: "json" // The data string will be returned as a JavaScript object.
 });

Change your success callback to look like this:

success: function (data) {
   // data = the response from the server
}

Or am I misunderstanding the question?

EDIT

I think I see you mentioned that you're using JSON as well. If you want jQuery to automatically parse the response text into a JavaScript Object, then add dataType: "json" to your $.ajax configuration.

$.ajax({
   type: "POST",
   url: "*****/process_delete.php",
   data: dataString,
   dataType: "json", // or use "text json" if that doesn't work
   success: function() {
       // Get results from form here
   }
});
