在玉模板(感叹号对象，哈希对象)中使用！{}和#{}插值 [英] Using !{ } and #{ } interpolation in a jade template (exclamation-object, hash-object)

问题描述

在一个玉器模板中(使用对node.js的表达)，我看到了一个使用以下语法的模板:

In a jade template (using express over node.js), I see a template using the following syntax:

script(type='text/template', id='data-services') !{data}

我不理解！{} 的构造；显然，它插值了在其他地方定义的javascript对象:

I don't understand the !{ } construct; apparently it interpolates a javascript object defined elsewhere as:

var data={ name:"Doe", age:"21" };

Jade docs&tut显示了使用#{} 进行插值，但是我看不到！{} .即使#{} 也没有记录，所以我认为它不是特定于玉器的.该语法从何而来?在何处得到记录?

Jade docs & tuts show the use of #{ } for interpolation, but I don't see !{ }. Even #{ } is not documented, so I think it's not jade-specific. Where does this syntax come from and where is it documented?

推荐答案

确实很难找到它.看看这个资源:

Quite difficult to find it, indeed. Have a look at this resource:

http://naltatis.github.io/jade-syntax-docs/#escaping

#用于要转义数据，而！则用于原始数据.

# is used when you want to escape data and ! when you want it raw.

例如，假设 name ="Hello< em> World</em>" .然后，您将拥有:

For example let's say that name = "Hello <em>World</em>". Then you have:

#{name} --> Hello <em>World</em>
!{name} --> Hello <em>World</em>

这样想:#将在编写时显示 name ，而！将其视为HTML.

Think about it like that: # will display name as it is written while ! will treat it as HTML.
