如果您有一个ID标签附加到与ng-controller相同的DOM元素,您可以访问一个角度元素的作用域:
DOM:
<div id="mycontroller" ng-controller="mycontroller"></div>
您的控制器:
function mycontroller($scope) { $scope.myfunction = function() { //do some stuff here } }
angular.element('#mycontroller').scope().myfunction();
记得打电话
angular.element('#mycontroller').scope().$apply()
