Javascript 链接承诺导致未定义

我在这个函数中不断遇到未定义的错误。它被分解为5个单独的函数，我尝试在前一个函数完成后运行每个函数，但使用前一个函数返回的数据。我可以嵌套所有回调，但我宁愿使用承诺

这里有很多问题。我会尽我所能描述尽可能多的。可能还有几个

d.resolve（所有站点）

需要在

completefunc

回调中，因为在填充

allSites

之前，您不想解析承诺

getSiteLibraries（）

和

searchLibraries（）

需要兑现承诺

findLibraries（）

和

parsearchresult（）

没有任何异步代码，因此不需要返回承诺，只需返回结果即可

$q.all（listPromise）。然后（findLibraries（listPromise））

实际立即执行

findLibraries（）

，只需使用

$q.all（listPromise）。然后（findLibraries）

。这同样适用于

$q.all（itemPromise）。然后（parseSearchResult（itemPromise））

这同样适用于

getAllSites()
    .then(
        getSiteLibraries(allSites)
        )
    .then(
        searchLibraries(allLibraries)
        );

改为：

getAllSites()
    .then(
        getSiteLibraries
        )
    .then(
        searchLibraries
        );
