angular ui modal after close event
提问by Safari
Is there a way I can call a function after a modal window got called (no matter if it happened with a button or by clicking on the backdrop)
有没有办法在调用模态窗口后调用函数（无论是使用按钮还是单击背景）
var dialog, options;
options = {
windowClass: "lightBox"
templateUrl: "url to the template",
controller: "some random controller",
scope: $scope
});
$("body").css({
'overflow': 'hidden'
});
dialog = $modal.open(options);
dialog.result.then(function() {
$("body").css({
'overflow': 'auto'
});
});
I want that everytime the modal windows closes the function in the result.then promise get executed. Now it just executes when i close the modal manually my $modalInstance.close(). But if i click on the backdrop this method doesn't get called
我希望每次模态窗口关闭结果中的函数。然后承诺被执行。现在它只是在我手动关闭模态时执行我的 $modalInstance.close()。但是如果我点击背景，这个方法不会被调用
any idea how i can do this?
知道我该怎么做吗？

I will assume that you are using the Modal dialogs from angular-ui. But before going into the details a bit of documentation around promises in AngularJS is needed. You need to know that every thenfunction can accept 3 parameters as such :
我将假设您使用的是 angular-ui 中的模态对话框。但是在进入细节之前，需要一些关于 AngularJS 中 promise 的文档。您需要知道每个then函数都可以接受 3 个参数，例如：
then(successCallback, errorCallback, notifyCallback)
- successCallbackis executed when the promise is resolved.
- errorCallbackis executed when the promise is rejected.
- notifyCallbackis executed when notified.
- 当 promise 被解决时，successCallback被执行。
- errorCallback在承诺被拒绝时执行。
- notifyCallback在收到通知时执行。
In the case of angular-ui's modal, clicking on the backdrop will result in a rejected promise. With this in mind, your code could be changed to :
对于 angular-ui 的模态，点击背景会导致被拒绝的承诺。考虑到这一点，您的代码可以更改为：
dialog.result.then(function () {
alert('Modal success at:' + new Date());
}, function () {
alert('Modal dismissed at: ' + new Date());
});

Angular 1.2 supports promises with a finally(callback):
Angular 1.2 支持 promise 为finally(callback)：
dialog.result.finally(function() {
alert('clean up resources');
});
