ajax运行php文件

I have this script in a .html file on my page and im trying to just run the getip.php file from here rather than to rename the file to .php. I tried this ajax call but its not working and not logging the ip in the logfile.txt. Please let me know what I am doing wrong.

Ajax in the head of the .html file:

 <script>
    $(document).ready(function() {
         $.ajax({

                type: "GET",
                url: "getip.php",

            }); // Ajax Call
        }); //event handler
   </script>

Code from getip.php:

<?php
// location of the text file that will log all the ip adresses
$file = 'logfile.txt';

// ip address of the visitor
$ipadress = $_SERVER['REMOTE_ADDR'];

// date of the visit that will be formated this way: 29/May/2011 12:20:03
$date = date('d/F/Y h:i:s');

// name of the page that was visited
$webpage = $_SERVER['SCRIPT_NAME'];

// visitor's browser information
$browser = $_SERVER['HTTP_USER_AGENT'];

// Opening the text file and writing the visitor's data
$fp = fopen($file, 'a');

fwrite($fp, $ipadress.' - ['.$date.'] '.$webpage.' '.$browser."
");

fclose($fp);
?>

Have you tried $.post() function instead? Example:

<script>
    $(document).ready(function() {
         $.post('getip.php'); // Ajax Call
        }); //event handler
</script>

You can also add a callback as a second parameter.

I would use the full URL for the ajax call. Depending on your framework you might not be hitting the intended endpoint. You could try echo 'test'; in your php file and adding a done handler to your ajax call to make sure you're hitting the php file in the first place:

.done(function( data ) {
  alert(data);
});
