Different AJAX result from different machines (simple code)

I have this jQuery AJAX and PHP code:

jQuery AJAX:

$.ajax({
    type: "post",
    url: "ajax/registration1.php",
    dataType: "text",
    success: function(request){                 
        if (request == "success")
            alert("registration1.php returns 'success'");
        else
            alert("registration1.php returns 'error'");
    }
});

PHP:

<?php
    echo "success";
?>

It works fine on my localhost, returns "registration1.php returns 'success'", but not on the other machine which returns 'error'.

Any ideas what I should check? Thanks.

FIXED:

He fixed the problem:

PHP is not being invoked when calling "registration1.php" directly, which causes the ajax() call to fail. If I wrap th开发者_运维技巧e form inside the Drupal framework, it appears to go through correctly.

I don't know why PHP was not being invoked though.

Thanks for the replies :)

make sure you put

header('Access-Control-Allow-Origin: *');

in your php file

<?php
    header('Access-Control-Allow-Origin: *');
    echo "success";
?>

do ajx request like

$.ajax({
    type: "post",
    url: "ajax/registration1.php",
    dataType: "text",
    crossDomain:true;
    success: function(request){                 
        if (request == "success")
            alert("registration1.php returns 'success'");
        else
            alert("registration1.php returns 'error'");
    },
   error:function(jxhr,resp){
        alert(jxhr.status);
        alert(jxhr.responseText);
   }
});

I would say there is a problem with your path.

Check the path is correct. And then check it again, cos it's not.
