Lightswitch html如何知道异步迭代何时完成. [英] Lightswitch html how to know when async iteration is done.

问题描述

您好，请您帮忙.

我在另一个异步操作中有一个异步操作，所以我怎么知道什么时候完成.

I have an async operation inside another async operation so how can i know when everything is done.

这是我的代码

var confirmedGirls = 0;

msls.showProgress(msls.promiseOperation(function(operation){{br/>        screen.Staff.getConfirmedWaiters().then(函数(结果){         item.getWaiter().then(function(result){ ;                                  }
    &b ;            });
      ;    operation.complete(confi rmedGirls);
            });
        }).then(function(result){

msls.showProgress(msls.promiseOperation(function (operation) {
            screen.Staff.getConfirmedWaiters().then(function (result) {
                result.each(function (item) {
                    item.getWaiter().then(function (result) {
                        if (result.Gender == "Female") {
                            confirmedGirls++;
                        }
                    });
                });
                operation.complete(confirmedGirls);
            });
        }).then(function (result) {

...

因此，首先我加载了ConfirmedWaiters集合，当它完成时，我将迭代每个实体并加载一个异步的子实体，因此我想知道迭代何时完成，但问题在于它会立即返回，因为其异步方式如何我可以吗 等到迭代完成，然后执行剩余的代码?

So first i load the ConfirmedWaiters collection, and when it's complete i iterate every entity and load a child entity async, so i want to know when the iteration is complete but the problem is that its returning right away because its async so how can i wait till the iteration is complete and then execute the remaining code?

谢谢

推荐答案

所以我想知道迭代何时完成，但问题在于它由于异步而立即返回，那么我如何才能等到迭代完成之后再执行其余代码?

so i want to know when the iteration is complete but the problem is that its returning right away because its async so how can i wait till the iteration is complete and then execute the remaining code?

在迭代完成之前，如何在应用程序中使用 await操作?

How about using await operation in your application till the iteration is complete.
