AngularJs directive-scope

1.scope：bool 或者 object代码：

<body ng-app="myApp">
    <div ng-controller="myCtrl">
        外部:{{myProperty}}
        <input  ng-model="myProperty"/>
        <br />
        <div my-directive></div>
    </div>
</body>

var app = angular.module('myApp',[]);
app.controller('myCtrl',function ($scope) {
  $scope.myProperty = '张三';
});
app.directive('myDirective',function () {
  return {
    restrict: 'A',scope: false,//继承但不隔离，控件内部，外部数据同步
    //scope:true,//继承并隔离，即template内部变量修改，不影响外部
    // scope:{},//隔离且不继承
    template: '<div class="bg-primary">内部：{{myProperty}} <input class="text-primary" ng-model="myProperty"/> </div>'
  }
});

2.scope制定object绑定

<body ng-app="myApp">
    <div class="container-fluid">
        <div ng-controller="myCtrl">
            外部:{{myProperty}}
            <br />
            <my-directive title="myProperty"></my-directive>
        </div>
    </div>
</body>

//定义模块，封装指令
angular.module('common',[])
.directive('myDirective',function () {
    return {
        restrict: 'E',//内部重新定义绑定字段名称
        scope: {
            //title: '@' //将标签定义的字符串，绑定显示
            title:'=' //将指令内部scope字段和指令外部模块scope字段双向绑定
        },template: '<div class="bg-primary">内部：{{title}} <input  class="text-primary" ng-model="title"/> </div>'
    }
});
//使用指令 myProperty对应外部绑定字段名称，title对应指令内部绑定名称
var app = angular.module('myApp',['common']);
app.controller('myCtrl',function ($scope) {
    $scope.myProperty = '张三';
});

3.绑定页面，指定的字符串内容，代码：

<body ng-app="myApp">
    <div side-Box title="TagCloud">
        <div class="tagcloud">
            <a href="">Graphics</a>
            <a href="">ng</a>
            <a href="">D3</a>
            <a href="">Front-end</a>
            <a href="">Startup</a>
        </div>
    </div>
</body>

angular.module('myApp',[])
    .directive('sideBox',function () {
        return {
            restrict: 'EA',scope: {
                title: '@'
            },transclude: true,template: '<div class="sideBox"><div class="content"><h2 class="header">' +
                '{{ title }}</h2><span class="content" ng-transclude></span></div></div>'
        };
    });
