问题描述
我正在使用带有nodejs和express的车把.这是我的main.handlebars文件:
I'm using handlebars with nodejs and express. This is my main.handlebars file:
<!doctype html>
<html>
<head>
...
</head>
<body>
<div class ="container">
...
<footer>
© {{copyrightYear}} Meadowlark Travel
</footer>
</div>
</body>
</html>
到目前为止，我已经将版权年度传递到了每条路线:
So far I'm passing the copyright year to every route:
var date = new Date();
var copyrightYear = date.getFullYear();
app.get(
'/',
function( req, res) {
res.render(
'home',
{
copyrightYear: copyrightYear
}
);
}
);
是否可以全局设置copyrightYear变量，所以我不必将其传递给每条路线/视图?
Is it possible to set the copyrightYear variable globally, so I don't have to pass it on to every route/view?
推荐答案
ExpressJS提供了某种全局变量".在文档中提到了它们: app.locals .要将其包含在每个响应中，您可以执行以下操作:
ExpressJS provides some kind of "global variables". They are mentioned in the docs: app.locals. To include it in every response you could do something like this:
app.locals.copyright = '2014';
