AngularJS : 使用 vm 从外部调用控制器函数
AngularJS : Call controller function from outside with vm
我这里有:
var app = angular.module('app');
app.controller("myController", function () {
var vm = this;
vm.myFunction = function() { alert('foo'); };
});
app.animation('.animate', ["$timeout", function($timeout) {
var vm = this;
return {
addClass: function(element, className, doneFn) {
$timeout(function() {
console.log('this is displayed');
vm.myFunction(); // Doesn't work !
});
}
}
}]);
当我在模板中添加 class 时,addClass
被触发。但是,vm.myFunction()
没有,因为它不存在。
我们如何在 angular 中做到这一点?
修改您的代码如下:
var app = angular.module('app');
app.controller('myController', function ($scope) {
var vm = this;
vm.myFunction = function() { alert('foo'); };
$scope = vm;
});
app.animation('.animate', ["$timeout", 'myController', function($timeout, myController) {
var vm = myController;
return {
addClass: function(element, className, doneFn) {
$timeout(function() {
console.log('this is displayed');
vm.myFunction(); // Doesn't work !
});
}
}
}]);
有些与您不同,但我认为这可以帮助您...
in HTML
<div id="outer" ng-controller="myController"></div>
in JS
var app = angular.module('app');
app.controller('myController', function ($scope) {
$scope.myFunction = function() { alert('foo'); };
});
var scope = angular.element($("#outer")).scope();
scope.myFunction();
