Controller中定义了$scope.method = function(){}
Directive中需要引入$scope
http://stackoverflow.com/questions/23636727/how-to-call-controller-function-from-directive
JS: angular.module(‘myApp‘, []) .controller(‘MyController‘, function($scope){ $scope.showAlert = function(value){ alert(‘Called from directive: ‘ + value); }; }) .directive(‘myDirective‘, function(){ return { restrict: ‘E‘, scope: { alert: ‘&‘ }, controller: function($scope){ $scope.value = ‘directive scope value‘; }, template: ‘<button ng-click="alert({message: value})">Alert</button>‘ } }); HTML: <body ng-app="myApp" ng-controller="MyController"> <my-directive alert="showAlert(message)"></my-directive> </body>
My recommendation is to use $emit instead of calling a method of the controller directly in your directive.
Directives should be always independent components, if inside the directive there is a call to a method from a controller(outside the directive) this will create a dependency between my directive and the controller and of course this will force one not being able to exist without the other.
If I would have to apply a design principle to a directive it will be the S in SOLID, Single responsibility principle. Directives should be able to encapsulate and work independently.
On my controller the event is captured using $on like:
$scope.$on("ValueChanged", function(event, ars){
... //your event has been triggered.
});或者
var directive= function ( $sessionStorage, $localStorage) { function work(scope, element, attrs, formCtrl) { var watchPromise = attrs.createClaimForm || null; element.bind(‘keypress‘, function (event) { //此处scope就是$scope scope.addBlankRowData(); } }); return { require: "form", restrict: "A", link: work } };
Controller中this.method = function(){}是获取不到的, 必须$scope
Angular1.0 在Directive中调用Controller的方法
