This requires runtime.js - in your projects. - - $ jade --client --no-debug < my.jade - -## Tags - - Tags are simply nested via whitespace, closing - tags defined for you. These indents are called "blocks". - - ul - li - a Foo - li - a Bar - - You may have several tags in one "block": - - ul - li - a Foo - a Bar - a Baz - -## Self-closing Tags - - Some tags are flagged as self-closing by default, such - as `meta`, `link`, and so on. To explicitly self-close - a tag simply append the `/` character: - - foo/ - foo(bar='baz')/ - - Would yield: - - <foo/> - <foo bar="baz"/> - -## Attributes - - Tag attributes look similar to HTML, however - the values are regular JavaScript, here are - some examples: - - a(href='google.com') Google - a(class='button', href='google.com') Google - - As mentioned the attribute values are just JavaScript, - this means ternary operations and other JavaScript expressions - work just fine: - - body(class=user.authenticated ? 'authenticated' : 'anonymous') - a(href=user.website || 'http://google.com') - - Multiple lines work too: - - input(type='checkbox', - name='agreement', - checked) - - Multiple lines without the comma work fine: - - input(type='checkbox' - name='agreement' - checked) - - Funky whitespace? fine: - - input( - type='checkbox' - name='agreement' - checked) - -## Boolean attributes - - Boolean attributes are mirrored by Jade, and accept - bools, aka _true_ or _false_. When no value is specified - _true_ is assumed. For example: - - input(type="checkbox", checked) - // => "<input type="checkbox" checked="checked" />" - - For example if the checkbox was for an agreement, perhaps `user.agreed` - was _true_ the following would also output 'checked="checked"': - - input(type="checkbox", checked=user.agreed) - -## Class attributes - - The _class_ attribute accepts an array of classes, - this can be handy when generated from a javascript - function etc: - - classes = ['foo', 'bar', 'baz'] - a(class=classes) - // => "<a class="foo bar baz"></a>" - -## Class literal - - Classes may be defined using a ".CLASSNAME" syntax: - - .button - // => "<div class="button"></div>" - - Or chained: - - .large.button - // => "<div class="large button"></div>" - - The previous defaulted to divs, however you - may also specify the tag type: - - h1.title My Title - // => "<h1 class="title">My Title</h1>" - -## Id literal - - Much like the class literal there's an id literal: - - #user-1 - // => "<div id="user-1"></div>" - - Again we may specify the tag as well: - - ul#menu - li: a(href='/home') Home - li: a(href='/store') Store - li: a(href='/contact') Contact - - Finally all of these may be used in any combination, - the following are all valid tags: - - a.button#contact(style: 'color: red') Contact - a.button(style: 'color: red')#contact Contact - a(style: 'color: red').button#contact Contact - -## Block expansion - - Jade supports the concept of "block expansion", in which - using a trailing ":" after a tag will inject a block: - - ul - li: a Foo - li: a Bar - li: a Baz - -## Text - - Arbitrary text may follow tags: - - p Welcome to my site - - yields: - - <p>Welcome to my site</p> - -## Pipe text - - Another form of text is "pipe" text. Pipes act - as the text margin for large bodies of text. - - p - | This is a large - | body of text for - | this tag. - | - | Nothing too - | exciting. - - yields: - - <p>This is a large - body of text for - this tag. - - Nothing too - exciting. - </p> - - Using pipes we can also specify regular Jade tags - within the text: - - p - | Click to visit - a(href='http://google.com') Google - | if you want. - -## Text only tags - - As an alternative to pipe text you may add - a trailing "." to indicate that the block - contains nothing but plain-text, no tags: - - p. - This is a large - body of text for - this tag. - - Nothing too - exciting. - - Some tags are text-only by default, for example - _script_, _textarea_, and _style_ tags do not - contain nested HTML so Jade implies the trailing ".": - - script - if (foo) { - bar(); - } - - style - body { - padding: 50px; - font: 14px Helvetica; - } - -## Template script tags - - Sometimes it's useful to define HTML in script - tags using Jade, typically for client-side templates. - - To do this simply give the _script_ tag an arbitrary - _type_ attribute such as _text/x-template_: - - script(type='text/template') - h1 Look! - p Jade still works in here! - -## Interpolation - - Both plain-text and piped-text support interpolation, - which comes in two forms, escapes and non-escaped. The - following will output the _user.name_ in the paragraph - but HTML within it will be escaped to prevent XSS attacks: - - p Welcome #{user.name} - - The following syntax is identical however it will _not_ escape - HTML, and should only be used with strings that you trust: - - p Welcome !{user.name} - -## Inline HTML - - Sometimes constructing small inline snippets of HTML - in Jade can be annoying, luckily we can add plain - HTML as well: - - p Welcome <em>#{user.name}</em> - -## Code - - To buffer output with Jade simply use _=_ at the beginning - of a line or after a tag. This method escapes any HTML - present in the string. - - p= user.description - - To buffer output unescaped use the _!=_ variant, but again - be careful of XSS. - - p!= user.description - - The final way to mess with JavaScript code in Jade is the unbuffered - _-_, which can be used for conditionals, defining variables etc: - - - var user = { description: 'foo bar baz' } - #user - - if (user.description) { - h2 Description - p.description= user.description - - } - - When compiled blocks are wrapped in anonymous functions, so the - following is also valid, without braces: - - - var user = { description: 'foo bar baz' } - #user - - if (user.description) - h2 Description - p.description= user.description - - If you really want you could even use `.forEach()` and others: - - - users.forEach(function(user){ - .user - h2= user.name - p User #{user.name} is #{user.age} years old - - }) - - Taking this further Jade provides some syntax for conditionals, - iteration, switch statements etc. Let's look at those next! - -## Assignment - - Jade's first-class assignment is simple, simply use the _=_ - operator and Jade will _var_ it for you. The following are equivalent: - - - var user = { name: 'tobi' } - user = { name: 'tobi' } - -## Conditionals - - Jade's first-class conditional syntax allows for optional - parenthesis, and you may now omit the leading _-_ otherwise - it's identical, still just regular javascript: - - user = { description: 'foo bar baz' } - #user - if user.description - h2 Description - p.description= user.description - - Jade provides the negated version, _unless_ as well, the following - are equivalent: - - - if (!(user.isAnonymous)) - p You're logged in as #{user.name} - - unless user.isAnonymous - p You're logged in as #{user.name} - -## Iteration - - JavaScript's _for_ loops don't look very declarative, so Jade - also provides its own _for_ loop construct, aliased as _each_: - - for user in users - .user - h2= user.name - p user #{user.name} is #{user.age} year old - - As mentioned _each_ is identical: - - each user in users - .user - h2= user.name - - If necessary the index is available as well: - - for user, i in users - .user(class='user-#{i}') - h2= user.name - - Remember, it's just JavaScript: - - ul#letters - for letter in ['a', 'b', 'c'] - li= letter - -## Mixins - - Mixins provide a way to define jade "functions" which "mix in" - their contents when called. This is useful for abstracting - out large fragments of Jade. - - The simplest possible mixin which accepts no arguments might - look like this: - - mixin hello - p Hello - - You use a mixin by placing `+` before the name: - - +hello - - For something a little more dynamic, mixins can take - arguments, the mixin itself is converted to a javascript - function internally: - - mixin hello(user) - p Hello #{user} - - +hello('Tobi') - - Yields: - - <p>Hello Tobi</p> - - Mixins may optionally take blocks, when a block is passed - its contents becomes the implicit `block` argument. For - example here is a mixin passed a block, and also invoked - without passing a block: - - mixin article(title) - .article - .article-wrapper - h1= title - if block - block - else - p No content provided - - +article('Hello world') - - +article('Hello world') - p This is my - p Amazing article - - yields: - - <div class="article"> - <div class="article-wrapper"> - <h1>Hello world</h1> - <p>No content provided</p> - </div> - </div> - - <div class="article"> - <div class="article-wrapper"> - <h1>Hello world</h1> - <p>This is my</p> - <p>Amazing article</p> - </div> - </div> - - Mixins can even take attributes, just like a tag. When - attributes are passed they become the implicit `attributes` - argument. Individual attributes can be accessed just like - normal object properties: - - mixin centered - .centered(class=attributes.class) - block - - +centered.bold Hello world - - +centered.red - p This is my - p Amazing article - - yields: - - <div class="centered bold">Hello world</div> - <div class="centered red"> - <p>This is my</p> - <p>Amazing article</p> - </div> - - If you use `attributes` directly, *all* passed attributes - get used: - - mixin link - a.menu(attributes) - block - - +link.highlight(href='#top') Top - +link#sec1.plain(href='#section1') Section 1 - +link#sec2.plain(href='#section2') Section 2 - - yields: - - <a href="#top" class="highlight menu">Top</a> - <a id="sec1" href="#section1" class="plain menu">Section 1</a> - <a id="sec2" href="#section2" class="plain menu">Section 2</a> - - If you pass arguments, they must directly follow the mixin: - - mixin list(arr) - if block - .title - block - ul(attributes) - each item in arr - li= item - - +list(['foo', 'bar', 'baz'])(id='myList', class='bold') - - yields: - - <ul id="myList" class="bold"> - <li>foo</li> - <li>bar</li> - <li>baz</li> - </ul> |
