javascript - 来自指令 Controller 的 Angular 调用 Controller 函数

Question

我有一个问题，应该很简单，但我找不到答案。

我有 Controller a:

app.controller('myController', function ($scope){

    $scope.MyParentFunction = function(){ 

              alert("it does not work..");

    };     

}

Controller b，位于指令内:

app.directive('myDirective', function () {

var directive = {};

    //properties
    directive.scope = {
        date: '=ngModel',
    },

    //controller
    directive.controller = function ($scope) {

        $scope.CallParentFunction = function(){

          //Call Function From Parent scope here
          $scope.MyParentFunction();     

        }

    },

    //call parent function in template
    directive.template = '<div ng-click="CallParentFunction()">Call</div>'; 

    return directive;

});

如何从指令 Controller 调用“MyParentFunction()”？提前致谢!

Answer 1

希望这会有所帮助:

您所需要的只是绑定(bind)您的父函数

directive.scope = {
    date: '=ngModel',
    callParentFunction: "&"  //function binding 
}
