没有正式的方法可以从模块中执行 ajax。
如果你在哪里开发一个组件，你可以调用你的组件 index.php?option=com_yourcomponent&task=getjsondata&view=yourview&format=json

这样你的文件views/yourview/view.json.php就会被调用，你可以在那里把你的数据发送出去，echo json_encode( array("success"=>true) ); jexit() 请注意使用jexit()insted oexit()

如果你真的需要从一个模块做 ajax，这里有一个在你的文件中导入 joomla 的技巧

<?php
if (! class_exists('JFactory') ) {
    define( 'DS', DIRECTORY_SEPARATOR );
    $rootFolder = explode(DS,dirname(__FILE__));
    $currentfolderlevel = 2;

    array_splice($rootFolder,-$currentfolderlevel);

    $base_folder = implode(DS,$rootFolder);


    if(is_dir($base_folder.DS.'libraries'.DS.'joomla'))
    {
        define( '_JEXEC', 1 );
        define('JPATH_BASE',implode(DS,$rootFolder));

        require_once ( JPATH_BASE .DS.'includes'.DS.'defines.php' );
        require_once ( JPATH_BASE .DS.'includes'.DS.'framework.php' );

        // Joomla is loaded! horray!
        $email = JRequest::getVar('email');
        $tags = implode(",",JRequest::getVar('tags',array()));

        $db = JFactory::getDbo();
        $db->setQuery("INSERT INTO `#__newsletter_users` (email,tags) VALUES('$email','$tags')");
        $db->query();

    }
}

?>

save_email.php在您的模块文件夹中创建一个像上面的文件（对我来说）并直接调用它。这是我的模块模板的一部分：

$.get('<?php echo JUri::base()."modules/mod_newsletter/save_email.php?email=" ?>'+email, function(data) {
    console.log(data);
    modal.hide();
});
