我环顾四周，找不到答案。我正在尝试运行一个promise，一旦所有facebookapi页面都被迭代并保存到一个数组中，它就会执行一个fulfill语句

我知道这个函数很难看，但我要看看我能在承诺方面走多远

function pageThroughLikes(facebookPostArray) {
  var testArray = []
  return new Promise(function (fulfill, reject) {
    facebookPostArray.forEach(function(array) {
      array.forEach(function(innerObject) {
        if ('likes' in innerObject) {
          if ('paging' in innerObject.likes) {
            if ('next' in innerObject.likes.paging) {
              nextPage = innerObject.likes.paging.next;
              currentPostId = innerObject.id;
              currentDataLength = innerObject.likes.data.length;
              i = 0;
              do{
                $.get(nextPage, function(nextLikePageData) {
                  likeData = {};
                  likeData.id = currentPostId;
                  likeData.likes = {};
                  likeData.likes.data = nextLikePageData.data
                  likeData.likes.paging = nextLikePageData.paging
                  console.log(likeData)
                  testArray.push(likeData);
                  facebookPostArray.push(testArray);
                  console.log('pushed to postArray')
                })
                i += 1;
                } while (currentDataLength != 0 && i > 10)
              }
           }
         }
      })
   });
   fulfill();
   console.log('paged through likes')
 })
}
现在，一旦这个函数完成，我想运行一个“测试”函数，将生成的数组转换成CSV格式并下载CSV文件

下面是我的测试函数：

function test() {
  var convertedPostCSV = convertArrayOfObjectsToCSV(postArray);
  downloadCSV(convertedPostCSV);
}
以下是我对函数的运行顺序：

$(document).ready(function() {
  getPostLikes().then(function() {
    pageThroughLikes(postArray).then(function() {
      test();
    });
  });
});
我正在努力解决的问题是，我的“test（）”函数在新页面的数据添加到我的“facebookPostArray”之前运行，或者在pageThroughLikes函数结束之前运行

希望有人能给我一些建议/给我指出正确的方向

好的，我已经按照@Winter Soldier的建议重新格式化了我的代码，但是我仍然得到了
processData
函数的一个未捕获错误

这是我的密码：
