Jade之条件语句

条件语句

jade支持js中的if/elseif/else语法。

jade：

- var user = { description: 'foo bar baz' }
- var authorised = false
#user
  if user.description
    h2 Description
    p.description= user.description
  else if authorised
    h2 Description
    p.description.
      User has no description,
      why not add one...
  else
    h1 Description
    p.description User has no description

html：

<div id="user">
  <h2>Description</h2>
  <p class="description">foo bar baz</p>
</div>

unless

jade还支持反面的条件语句unless。

jade：

- var user = { name: 'Tom' }
unless user.isAnonymous
  p You're logged in as #{user.name}

html：

<p>You're logged in as Tom</p>
