Escaping


We have seen that HTML in variables is escaped by using escaped interpolation constructs != or !{}. How about escaping the Jade interpolation constructs =, !=, #{}, and !{}?

Jade interpolation constructs can be escaped with the combination of backslash (\) and the &#61 HTML entity:

Jade

Rendered HTML

p
= message

= message

p
  != message

!= message

p \#{message}

#{message}

p \!{message}

!{message}

p \\#{message}

\#{message}

p \\!{message}

\!{message}

Using the &#61 HTML entity code makes Jade render = in the browser, rather than interpret it as the Jade interpolation construct.

# and ! are escaped using the popular escape character, backslash (\). If you intend to use \ as a literal, you will need to escape it too with \, as shown in the preceding example.
