如何在AngularJS的Run块中等待诺言? [英] How to wait for a promise in a Run block in AngularJS?

问题描述

我真的需要在引导角度之前加载一些数据.由于这个原因，我创建了一个run块/在这个run块中，我在服务上调用了一个方法，该方法从服务器加载一些数据.由于这是一个异步调用，因此JavaScript可以进一步提高执行力，这会导致我的应用程序中出现一些未定义的对象.

I really need some data to be loaded before bootstrapping angular. For this reason I've created a run block/ Within this run block I call a method on a service which load some data from the server. Since this is a async call, JavaScript gets further with execution, which results in some undefined objects in my app.

我正在使用路由，但不能使用resolve属性.

I am working with routes, but it is not an option to work with the resolve property.

有人可以提供有关如何等待run块中的诺言的解决方案吗?

Could someone provide a solution on how to wait for a promise to be ready in the run block?

感谢给出的答案，我已经通过手动引导角度来解决了这个问题:

Thanks to the given answers, I have solved it by manually bootstrapping angular:

$(document).ready(function () {
    $.ajax('/Data/GetDropdownData', {type:'POST'}).done(function (response) {
        app.run(['ListService',  function (ListService) {
            ListService.setData(response);
        }])

        angular.bootstrap(document, ["sma"]);
    })
})

推荐答案

我评论过将其放在此处

您可以尝试手动引导程序

<script> 
   angular.element(document).ready(function() {
      angular.bootstrap(document); 
   });
</script>

在这种情况下，您不能使用控制器和角度方式获取数据.我认为您将必须通过jQuery加载数据，在jquery回调中引导角度，然后使用从jquery获得的数据初始化您的作用域变量.

Of cause in this case you cannot use controllers and angular way of getting data. I think you would have to load your data by jQuery, bootstrap your angular in jquery callback and then init your scope variable with data you got from jquery.
