Detailed explanation of how to implement custom instructions in AngularJS

//第一种
angular.module('MyApp',[])
.directive('zl1',zl1)
.controller('con1',['$scope',func1]);
function zl1(){
  var directive={
    restrict:'AEC',
   template:'this is the it-first directive',
  };
  return directive;
};
function func1($scope){
  $scope.name="alice";
}
//第二种
angular.module('myApp',[]).directive('zl1',[ function(){
 return {
  restrict:'AE',
  template:'thirective',
  link:function($scope,elm,attr,controller){
   console.log("这是link");
  },
  controller:function($scope,$element,$attrs){
   console.log("这是con");
  }
 };
}]).controller('Con1',['$scope',function($scope){
 $scope.name="aliceqqq";
}]);

angular.module('myApp', []).directive('first', [ function(){
  return {
    // scope: false, // 默认值，共享父级作用域
    // controller: function($scope, $element, $attrs, $transclude) {},
    restrict: 'AE', // E = Element, A = Attribute, C = Class, M = Comment
    template: 'first name:{{name}}',
  };
}]).directive('second', [ function(){
  return {
    scope: true, // 继承父级作用域并创建指令自己的作用域
    // controller: function($scope, $element, $attrs, $transclude) {},
    restrict: 'AE', // E = Element, A = Attribute, C = Class, M = Comment
    //当修改这里的name时，second会在自己的作用域中新建一个name变量，与父级作用域中的
    // name相对独立，所以再修改父级中的name对second中的name就不会有影响了
    template: 'second name:{{name}}',
  };
}]).directive('third', [ function(){
  return {
    scope: {}, // 创建指令自己的独立作用域，与父级毫无关系
    // controller: function($scope, $element, $attrs, $transclude) {},
    restrict: 'AE', // E = Element, A = Attribute, C = Class, M = Comment
    template: 'third name:{{name}}',
  };
}])
.controller('DirectiveController', ['$scope', function($scope){
  $scope.name="mike";
}]);
