嘿，我是angularjs Im的新手，我在angularjs中使用controlleras样式，因为代码是可表示的并且是网络。我的问题是在 Controller 中调用子功能我的代码如下
//AngularJS CODE
(function(){
'use strict';
angular.module('mAPP', ['ngMaterial']);
function helpM(){
var vm = this;
vm.SaveM = function(){
alert('Save Me Now');
}
}
function SaveCTRL(){
var vm = this;
vm.nineOne = helpM.SaveM;
}
angular.module('mAPP')
.controller('SaveCTRL', [SaveCTRL]);
})();
// HTML代码
<div ng-controller="SaveCTRL as main" layout="column" ng-cloak="" class="md-inline-form" ng-app="mAPP">
<md-button class="md-raised md-primary" ng-click="main.nineOne()">Submit</md-button>
</div>
但是警报并没有执行，非常感谢:(
最佳答案
您必须创建helpM的实例，否则this将是undefined
(function() {
'use strict';
angular.module('myApp', []);
function helpM() {
var vm = this;
vm.SaveM = function() {
alert('Save Me Now');
}
return vm;
}
function SaveCTRL() {
var vm = this;
vm.nineOne = new helpM().SaveM;
return vm;
}
angular.module('myApp')
.controller('SaveCTRL', SaveCTRL);
})();<body ng-app="myApp">
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-controller="SaveCTRL as main" layout="column" ng-cloak="" class="md-inline-form">
<md-button class="md-raised md-primary" ng-click="main.nineOne()">Submit</md-button>
</div>
</body>
