我正在使用Jasmine独立https://github.com/jasmine/jasmine/releases
我在SpecRunner.html中声明了一个全局变量global_song（我可以从chrome控制台访问它，所以它真的是全局的），其中包含我试图将global_song连接到“应该能够播放Song”的脚本：< / p>
it("should be able to play Song " + global_song, function() {
player.play(song);
expect(player.currentlyPlayingSong).toEqual(global_song);
//demonstrates use of custom matcher
expect(player).toBePlaying(song);
});
为什么它无法访问global_song变量？
更新：expect(player.currentlyPlayingSong).toEqual(global_song)有效，而it("should be able to play Song " + global_song无效。

你在哪里定义了global_song？如果你在beforeEach（）函数中执行了这个操作，那么这个行为就有意义了，因为describe块（它试图定义你的it（）函数）中的代码在before {（3}}其他SO中描述的beforeEach（）之前执行。回答。

我想假设你的 $paths = array(APP_LIBS.DIRECTORY_SEPARATOR.'Doctrine'.DIRECTORY_SEPARATOR.'Entity');
// the connection configuration
$dbParams = array(
'dbname' => $di->get('config')->database->dbname,
'user' => $di->get('config')->database->username,
'password' => $di->get('config')->database->password,
'host' => $di->get('config')->database->host,
'port' => (int)$di->get('config')->database->port,
'charset' => 'UTF8',
'driver' => 'pdo_mysql'
);
$config = Setup::createAnnotationMetadataConfiguration($paths, $di->get('env')->isDebugActive(), APP_PATH_CACHE_DOCTRINE, null, false);
$config->setAutoGenerateProxyClasses($di->get('env')->isDev());
$driverChain = new Doctrine\Common\Persistence\Mapping\Driver\MappingDriverChain();
$cachedAnnotationReader = $config->getMetadataDriverImpl()->getReader();
\Gedmo\DoctrineExtensions::registerAbstractMappingIntoDriverChainORM($driverChain, $cachedAnnotationReader);
$driverChain->addDriver($config->getMetadataDriverImpl(), "Doctrine\Entity");
$config->setMetadataDriverImpl($driverChain);
if ((bool)$di->get('config')->application->sqlLog)
{
$config->setSQLLogger(new \Doctrine\Logger\FileSQLLogger());
}
$config->addCustomNumericFunction('RAND', 'Doctrine\Custom\Functions\Rand');
$config->addCustomStringFunction('REGEXP', 'Doctrine\Custom\Functions\Regexp');
$config->addCustomStringFunction('CONCAT_WS', 'Doctrine\Custom\Functions\ConcatWs');
// create event manager and hook preferred extension listeners
$evm = new Doctrine\Common\EventManager();
// gedmo extension listeners, remove which are not used
// sluggable
$sluggableListener = new Gedmo\Sluggable\SluggableListener;
// you should set the used annotation reader to listener, to avoid creating new one for mapping drivers
$sluggableListener->setAnnotationReader($cachedAnnotationReader);
$evm->addEventSubscriber($sluggableListener);
// tree
$treeListener = new Gedmo\Tree\TreeListener;
$treeListener->setAnnotationReader($cachedAnnotationReader);
$evm->addEventSubscriber($treeListener);
// loggable, not used in example
$loggableListener = new Gedmo\Loggable\LoggableListener;
$loggableListener->setAnnotationReader($cachedAnnotationReader);
$evm->addEventSubscriber($loggableListener);
// timestampable
$timestampableListener = new Gedmo\Timestampable\TimestampableListener;
$timestampableListener->setAnnotationReader($cachedAnnotationReader);
$evm->addEventSubscriber($timestampableListener);
// translatable
$translatableListener = new Gedmo\Translatable\TranslatableListener;
// current translation locale should be set from session or hook later into the listener
// most important, before entity manager is flushed
$translatableListener->setTranslatableLocale('en');
$translatableListener->setDefaultLocale('en');
$translatableListener->setAnnotationReader($cachedAnnotationReader);
$evm->addEventSubscriber($translatableListener);
// sortable, not used in example
$sortableListener = new Gedmo\Sortable\SortableListener;
$sortableListener->setAnnotationReader($cachedAnnotationReader);
$evm->addEventSubscriber($sortableListener);
// mysql set names UTF-8 if required
$evm->addEventSubscriber(new Doctrine\DBAL\Event\Listeners\MysqlSessionInit());
$entityManager = EntityManager::create($dbParams, $config, $evm);
$platform = $entityManager->getConnection()->getDatabasePlatform();
\Doctrine\DBAL\Types\Type::addType('json', '\Sonata\Doctrine\Types\JsonType');
$platform->registerDoctrineTypeMapping("json", 'json');
$platform->registerDoctrineTypeMapping('enum', 'string');
在执行
global_song这种方式在测试中不可用作player.play(song);
的第一个参数，并且在it断言中执行player.play后可用。
尝试从expect(player.currentlyPlayingSong).toEqual(global_song)单独添加简单作业global_song，以验证它在执行player.play之前是否可用：
player.play只需查看该示例，以说明问题的主要候选人：
window.global_song = 'value'
