Directive

一個最基本的Directive 是這樣的

app = angular.module 'myApp', []

app.directive "superman", ->
    restrict: "E"
    template: "<div>superman save the world</div>"

restrict 中文叫限制，前面的例子restrict: 'E'就是限制directive 爲Element，default 是restrict: 'A'

再看下一個

app = angular.module 'myApp', []

app.directive "superman", ->
    restrict: "A"
    link: ->
        alert('it's work)

restrict: 'A' A for attritube 就是用在html element 的attritubes

restrict: 'C' C for class

restrict: 'M' M for comment，comment 用法比較詭異，來看例子

<!-- directive:superman -->

簡化

app = angular.module 'myApp', []

app.directive "superman", ->
    (scope, element)->
        console.log element

Isolate Scope

isolate scope 這東西是有點難懂，我還是儘量的把它搞懂了isolate scope 有三種形式

```coffeescript main.coffee app.directive “drink”, -> scope: flavor: ‘@’ template: “{{flavor}}”


```jade index.jade
div(ng-controller="AppCtrl")
    div(drink flavor="cherry")

app.controller "AppCtrl", ($scope) ->
    $scope.ctrlFlavor = "shit"

app.directive "drink", ->
    scope:
        flavor: "="
    template: "{{flavor}} flavor is good"

jade index.jade div(ng-controller="AppCtrl") div(drink flavor="ctrlFlavor")
