不久前发布了一篇教程，介绍了如何使用ajax通知发布/更新帖子，下面是其中的代码：

function my_post_type_xhr(){
    global $post;
    if(\'my_post_type\' === $post->post_type){
        $post_url = admin_url(\'post.php\'); #In case we\'re on post-new.php
        echo "
        <script>
            jQuery(document).ready(function($){
                //Click handler - you might have to bind this click event another way
                $(\'input#publish, input#save-post\').click(function(){
                    //Post to post.php
                    var postURL = \'$post_url\';

                    //Collate all post form data
                    var data = $(\'form#post\').serializeArray();

                    //Set a trigger for our save_post action
                    data.push({foo_doing_ajax: true});

                    //The XHR Goodness
                    $.post(postURL, data, function(response){
                        var obj = $.parseJSON(response);
                        if(obj.success)
                            alert(\'Successfully saved post!\');
                        else
                            alert(\'Something went wrong. \' + response);
                    });
                    return false;
                });
            });
        </script>";
    }
}
add_action(\'admin_head-post.php\', \'my_post_type_xhr\');
add_action(\'admin_head-post-new.php\', \'my_post_type_xhr\');

 add_action(\'save_post\', \'save_my_post_type\');
function save_my_post_type($post_id){
    if (defined(\'DOING_AUTOSAVE\') && DOING_AUTOSAVE) return;

    #If this is your post type
    if(\'my_post_type\' === $_POST[\'post_type\']){
        //Save any post meta here

        #We conditionally exit so we don\'t return the full wp-admin load if foo_doing_ajax is true
        if(isset($_POST[\'foo_doing_ajax\']) && $_POST[\'foo_doing_ajax\'] === true){
            header(\'Content-type: application/json\');
            #Send a response
            echo json_encode(array(\'success\' => true));
            exit;
            #You should keep this conditional to degrade gracefully for no JS
        }
    }
}

在该代码段中，没有弹出消息表明该帖子类型已保存。在该代码段中，您可以在离开帖子类型时发出警告，询问您是否要离开，即使帖子已更新

谢谢
