提问by user2167582
I have a file input
我有一个文件输入
<input type="file" ng-change="action()">
<input type="file" ng-change="action()">
Now in my controller I dont want to do selectors and stuff. so I just have
现在在我的控制器中，我不想做选择器之类的事情。所以我只有
$scope.action = () ->
...
However, I want a certain behavior such that as long as user selects a File the $scope.action is called, instead of onchange is there onselect event in angular?
但是，我想要某种行为，只要用户选择一个文件，就会调用 $scope.action，而不是 onchange 是否有 onselect 事件？

Use thisss
用这个
<input ng-model="photo"
onchange="angular.element(this).scope().file_changed(this)"
type="file" accept="image/*" />
$scope.file_changed = function(element, $scope) {
$scope.$apply(function(scope) {
});
});
