doctype
关于文档的类型 默认是html
doctype html<!DOCTYPE html>
简洁文档类型标记
- xml
- <?xml version="1.0" encoding="utf-8" ?>
- transitional
- <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
- strict
- <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
- frameset
- <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Frameset//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-frameset.dtd">
- 1.1
- <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">
- basic
- <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML Basic 1.1//EN" "http://www.w3.org/TR/xhtml-basic/xhtml-basic11.dtd">
- mobile
- <!DOCTYPE html PUBLIC "-//WAPFORUM//DTD XHTML Mobile 1.2//EN" "http://www.openmobilealliance.org/tech/DTD/xhtml-mobile12.dtd">
You can also use your own literal custom doctype:
doctype html PUBLIC "-//W3C//DTD XHTML Basic 1.1//EN"<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML Basic 1.1//EN">标签
默认，每行最开始的（或者在空格之后的（只有空格））代表一个html 标签 ，可以嵌入缩进，创建像html 文档结构的样式。
ul
li Item A
li Item B
li Item C<ul>
<li>Item A</li>
<li>Item B</li>
<li>Item C</li>
</ul>
jade 也知道那种标签是可以自己关闭的。
img<img/>
Block 扩展
jade 提供的支持内联的嵌入标签
a: img<a><img/></a>属性
标签属性看起来比较像html, 然后它们的值只是规则的javascript.
a(href='google.com') Google
a(class='button', href='google.com') Google<a href="google.com">Google</a>
<a class="button" href="google.com">Google</a>
普通的javascript扩展也可以使用:
- var authenticated = true
body(class=authenticated?'authed':'anon')<body class="authed"></body>
Boolean 属性
input(type='checkbox', checked)
input(type='checkbox', checked=true)
input(type='checkbox', checked=false)
input(type='checkbox', checked=true.toString())<input type="checkbox" checked="checked" />
<input type="checkbox" checked="checked" />
<input type="checkbox" />
<input type="checkbox" checked="true" />
doctype html
input(type='checkbox', checked)
input(type='checkbox', checked=true)
input(type='checkbox', checked=false)
input(type='checkbox', checked=true && 'checked')<!DOCTYPE html>
<input type="checkbox" checked>
<input type="checkbox" checked>
<input type="checkbox">
<input type="checkbox" checked="checked">
Class 属性
类属性只是简单的字符串、 但是它们可以代表一系列类名, 它们是从javascript中生成的.
- var classes = ['foo', 'bar', 'baz']
a(class=classes)
//- the class attribute may also be repeated to merge arrays
a.bing(class=classes class=['bing'])<a class="foo bar baz"></a>
<a class="foo bar baz bing"></a>
Class 字面名称
就是html 标签中class 属性的名称
a.button<a class="button"></a>
默认的标示是div:
.content<div class="content"></div>
ID 字面名称
就是html 标签中id属性的名称
a#main-link<a id="main-link"></a>
默认是div
#content<div id="content"></div>存文本
Jade提供了三中方式. 、
Piped Text
使用 | 字符
| Plain text can include <strong>html</strong>
p
| It must always be on its own linePlain text can include <strong>html</strong>
<p>It must always be on its own line</p>
内联标签
p Plain text can include <strong>html</strong><p>Plain text can include <strong>html</strong></p>
块标签
使用. 一个较好的例子就是script 和style. 为了这样做，你仅仅使用 . 在一个标签之后（没有空格）
script.
if (usingJade)
console.log('you are awesome')
else
console.log('use jade')<script>
if (usingJade)
console.log('you are awesome')
else
console.log('use jade')
</script>代码
Jade 可以进行javascript代码的编写.
非缓存代码
Unbuffered 代码以- 开始.
- for (var x = 0; x < 3; x++)
li item<li>item</li>
<li>item</li>
<li>item</li>
缓存代码
缓存代码以= 开始
p
= 'This code is <escaped>!'<p>This code is <escaped>!</p>
p= 'This code is' + ' <escaped>!'<p>This code is <escaped>!</p>
注释
// just some paragraphs
p foo
p bar<!-- just some paragraphs -->
<p>foo</p>
<p>bar</p>
//- will not output within markup
p foo
p bar<p>foo</p>
<p>bar</p>
块注释
body
//
As much text as you want
can go here.<body>
<!--
As much text as you want
can go here.
-->
</body>条件
进行判断
- var user = { description: 'foo bar baz' }
#user
if user.description
h2 Description
p.description= user.description
else
h1 Description
p.description User has no description<div id="user">
<h2>Description</h2>
<p class="description">foo bar baz</p>
</div>
unless user.isAnonymous
p You're logged in as #{user.name}if !user.isAnonymous
p You're logged in as #{user.name}迭代
ul

li= val<ul>
<li>1</li>

</ul>
Case语句
- var friends = 10
case friends
when 0
p you have no friends
when 1
p you have a friend
default
p you have #{friends} friends<p>you have 10 friends</p>
Case Fall Through
- var friends = 0
case friends
when 0
when 1
p you have very few
default
p you have #{friends} friends<p>you have very few friends</p>
Block 扩展
- var friends = 1
case friends
when 0: p you have no friends
when 1: p you have a friend
default: p you have #{friends} friends<p>you have a friend</p>过滤
