  36. I am a canvas for building HTML.
  37. I provide the `#tag:` method to create a `TagBrush` (wrapping a DOM element) and convenience methods in the `tags` protocol.
  38. ## API
  39. My instances are used as the argument of the `#renderOn:` method of `Widget` objects.
  40. The `#with:` method is used to compose HTML, nesting tags. `#with:` can take a `TagBrush`, a `String`, a `BlockClosure` or a `Widget` as argument.
  41. ## Usage example:
  42. aCanvas a
  43. with: [ aCanvas span with: 'click me' ];
  44. onClick: [ window alert: 'clicked!!' ]!

  425. My sole instance is the registry of html snippets.
  426. `HTMLSnippet current` is the public singleton instance.
  427. On startup, it scans the document for any html elements
  428. with `'data-snippet="foo"'` attribute and takes them off the document,
  429. remembering them in the store under the specified name.
  430. It also install method #foo into HTMLCanvas dynamically.
  431. Every html snippet should mark a 'caret', a place where contents
  432. can be inserted, by 'data-snippet="*"' (a special name for caret).
  433. For example:
  434. `<li data-snippet='menuelement' class='...'><a data-snippet='*'></a></li>`
  435. defines a list element with a link inside; the link itself is marked as a caret.
  436. You can later issue
  437. `html menuelement href: '/foo'; with: 'A foo'`
  438. to insert the whole snippet and directly manipulate the caret, so it renders:
  439. `<li class='...'><a href='/foo'>A foo</a></li>`
  440. For a self-careting tags (not very useful, but you do not need to fill class etc.
  441. you can use
  442. `<div class='lots of classes' attr1='one' attr2='two' data-snippet='*bar'></div>`
  443. and in code later do:
  444. `html bar with: [ xxx ]`
  445. to render
  446. `<div class='lots of classes' attr1='one' attr2='two'>...added by xxx...</div>`!

  519. I am a brush for building a single DOM element (which I hold onto).
  520. All tags but `<style>` are instances of me (see the `StyleBrush` class).
  521. ## API
  522. 1. Nesting
  523. Use `#with:` to nest tags. `#with:` can take aString, `TagBrush` instance, a `Widget` or block closure as parameter.
  524. Example: `aTag with: aString with: aCanvas div`
  525. 2. Events
  526. The `events` protocol contains all methods related to events (delegating event handling to jQuery).
  527. Example: `aTag onClick: [ window alert: 'clicked' ]`
  528. 3. Attributes
  529. The `attribute` protocol contains methods for attribute manipulation (delegating to jQuery too).
  530. Example: `aTag at: 'value' put: 'hello world'`
  531. 4. Raw access and jQuery
  532. The `#element` method can be used to access to JavaScript DOM element object.
  533. Example: `aTag element cssStyle`
  534. Use `#asJQuery` to access to the receiver converted into a jQuery object.
  535. Example: `aTag asJQuery css: 'color' value: 'red'`!
