调用父控制器的方法从AngularJS指令 [英] calling method of parent controller from a directive in AngularJS
问题描述
随着我的previous <一个href=\"http://stackoverflow.com/questions/15990122/passing-object-to-angularjs-directive-from-the-controller\">question,现在我想从我的指令调用父控制器上的方法。我得到一个未定义的参数。这是我做的：
Following my previous question, I'm now trying to call a method on the parent controller from my directive. I get an undefined parameter. Here's what I do:
<body ng-app="myApp" ng-controller="MainCtrl">
<span>{{mandat.rum}}</span>
<span>{{mandat.surname}}</span>
<input type="text" ng-model="mandat.person.firstname" />
<my-directive mandate-person="mandat.person" updateparent="updatePerson()" >
</my-directive>
</body>
和脚本：
var app = angular.module('myApp', []);
app.controller('MainCtrl', function ($scope) {
$scope.mandat = { name: "John", surname: "Doe", person: { id: 1408, firstname: "sam" } };
$scope.updatePerson = function(person) {
alert(person.firstname);
$scope.mandat.person = person;
}
});
app.directive('myDirective', function () {
return {
restrict: 'E',
template: "<div><span>{{mandatePerson.id}}<span><input type='text' ng-model='mandatePerson.firstname' /><button ng-click='updateparent({person: mandatePerson})'>click</button></div>",
replace: true,
scope: { mandatePerson: '=', updateparent: '&' }
}
}
)
时的updatePerson方法被调用，人是不确定的。
when the updatePerson method gets called, person is undefined.

推荐答案
只是简单的改变你的HTML如下
Just simple change your html as below
<my-directive mandate-person="mandat.person" updateparent="updatePerson(person)" >
</my-directive>
你是不是通过人用的updatePerson这就是为什么它不工作
you are not passing "person" with updatePerson thats why it is not working
