简单的ajax记事本

记事本，同时只能记录一个文件，存为了txt文本文档

注意本例用了一些css和js文件，请在演示页面另存为后查看

演示

 

PHP Code

<?php

$note_name = 'note.txt';
$uniqueNotePerIP = true;

if($uniqueNotePerIP){

    // Use the user's IP as the name of the note.
    // This is useful when you have many people
    // using the app simultaneously.

    if(isset($_SERVER['HTTP_X_FORWARDED_FOR'])){
        $note_name = 'notes/'.md5($_SERVER['HTTP_X_FORWARDED_FOR']).'.txt';
    }
    else{
        $note_name = 'notes/'.md5($_SERVER['REMOTE_ADDR']).'.txt';
    }
}


if(isset($_SERVER['HTTP_X_REQUESTED_WITH'])){
    // This is an AJAX request

    if(isset($_POST['note'])){
        // Write the file to disk
        file_put_contents($note_name, $_POST['note']);
        echo '{"saved":1}';
    }

    exit;
}

$note_content = '

                Write your note here.

             It will be saved with AJAX.';

if( file_exists($note_name) ){
    $note_content = htmlspecialchars( file_get_contents($note_name) );
}

?>

 

XML/HTML Code

<div id="pad">
            <h2>Note</h2>
            <textarea id="note"><?php echo $note_content ?></textarea>
        </div>
