Question

我有一个简单的菜单，想显示登录名和其他帐户的链接。

我确定我可以使用此功能，但是对js文件进行一些更改后，该功能将不再可用。

我知道它会很简单，但是无法弄清楚。非常感谢您的帮助。

<script type="text/javascript">
    if ( MageCustomer.name !== undefined ) {
        $( '.mm-account' ).removeClass( 'hide' ).find( '.name' ).text( MageCustomer.name );
    } else {
        $( '.mm-login' ).removeClass( 'hide' );
    }
</script>
<ul>
    <li class="mm-login hide"><a href="{{config path=" web/unsecure/base_url "}}customer/account/login">Login/Join</a>
    </li>
    <li class="mm-account hide"><a href="{{config path=" web/unsecure/base_url "}}customer/account">My Account (<span class="name green"></span>)</a>
    </li>
    <li class="mm-account hide"><a href="{{config path=" web/unsecure/base_url "}}customer/account/logout">Logout</a>
    </li>
    <li><a href="{{config path=" web/unsecure/base_url "}}ordering-information">Ordering Information</a>
    </li>
    <li><a href="{{config path=" web/unsecure/base_url "}}shipping-options">Delivery Info</a>
    </li>
    <li><a href="{{config path=" web/unsecure/base_url "}}terms-and-conditions">Free Returns</a>
    </li>
    <li><a href="{{config path=" web/unsecure/base_url "}}contacts">Contact Us</a>
    </li>
    <li><a href="{{config path=" web/unsecure/base_url "}}faq">FAQ</a>
    </li>
</ul>

控制台错误是这个。

如果（MageCustomer.name！==未定义）{
