结束事件后的角度ui模态 [英] angular ui modal after close event

问题描述

有没有一种方法可以在调用模式窗口后调用函数(无论它是通过按钮发生还是通过单击背景而发生)

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)

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'
  });
});

我希望每次模态窗口关闭结果中的函数后，然后保证执行.现在，当我手动关闭$ modalInstance.close()模态时，它才执行.但是，如果我在背景上单击，则不会调用此方法

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

知道我该怎么做吗?

推荐答案

我假设您正在使用angular-ui的模态"对话框.但是在进入细节之前，需要一些有关AngularJS中的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:

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 then function can accept 3 parameters as such :

then(successCallback, errorCallback, notifyCallback) 

兑现承诺后，将执行
• successCallback .
当拒绝承诺时，会执行
• errorCallback .
收到通知时执行
• notifyCallback .
• successCallback is executed when the promise is resolved.
• errorCallback is executed when the promise is rejected.
• notifyCallback is executed when notified.

对于angular-ui的模态，单击背景将导致被拒绝的承诺.考虑到这一点，您的代码可以更改为:

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 :

dialog.result.then(function () {
  alert('Modal success at:' + new Date());
}, function () {
  alert('Modal dismissed at: ' + new Date());
});
