您可以在玉中引用带有破折号的变量吗?

问题描述

我正在尝试在我的翡翠模板中做这样的事情

I'm trying to do something like this in my jade template

a.apply-url(href="#{apply-url}")

但它被解释为应用减去 url"

But it's being interpreted as 'apply minus url'

有没有办法强制解释器做正确的事情?或者有什么方法可以引用顶级对象，并将索引放在引号中，像这样?

Is there a way I can force the interpreter to do the right thing? Or is there some way to refer to a top-level object, and put the index in quotes, like this?

a.apply-url(href="#{this['apply-url']}")

推荐答案

我对 Jade 不是很熟悉，但我之前研究过一点.在 here 玩了一段时间后，我能够让它工作:

I'm not all that familiar with Jade, but I have looked into it a little bit before. After playing around a while here, I was able to get this to work:

a.apply-url(href="#{locals['apply-url']}")

{"apply-url": "foo"}

产生:

<a href="foo" class="apply-url"></a>

这是可行的，因为这个特定的实现将数据存储在名为 locals 的局部变量中，然后由模板函数关闭.据我所知，这是一个实现细节，我不一定期望它在其他 Jade 实现中也能工作.

This works because this particular implementation stores the data in a local variable named locals which is then closed over by the templating function. As far as I can tell, this is an implementation detail, and I wouldn't necessarily expect this to work in other Jade implementations.
