jquery ajax call - get returning value if dataType is simply a text (string)

Question

I have the following code.

    $.ajax({
    type: "POST",
    url:"blahblah.php",
    data: "{}",
    async: true,
    dataType: "text",
    success: function() {
       if(returning data from blahblah.php == true)
           window.location.href="http://www.blahblah.com/logout.php";
    }
}); 

1) No data need to be sent.

2) File "blahblah.php" does some processing and returns either true or false.

3) I want to get the response and If true redirect to another php page.

I do not know how to read the returning data of the function in the blahblah.php file!!

Thank you in advance. George

Answer 1

Have you tried setting dataType to 'json'? Also, you're not actually retrieving the response from the server on a successful callback. Try this:

    $.ajax({
      type: "POST",
      url:"blahblah.php",
      data: "{}",
      async: true,
      dataType: "json",
      success: function(response) {
         if(response == true) {
             window.location.href="http://www.blahblah.com/logout.php";
         }
      }
   });

If your success event is not call then you may be get return data using complete event

example

complete: function (data) {
    alert(data.responseText);
  },

using this you can get response data in this event

You have to pass a variable into the success call.

$.ajax({
    type: "POST",
    url:"blahblah.php",
    data: "{}",
    async: true,
    dataType: "text",
    success: function( data ) {

        console.log(data);

    }
}); 

If the success method runs then you have successfully submitted the file and can redirect with a simple document.location = "http://www.example.com/somewhere.php
