解析Promises，destroyAll（）;不工作？

Question

以下代码中的第二行未在云作业期间执行，为什么会出现这种情况？前一行运行良好。

Parse.Object.destroyAll(apples).then(function() {
  return Parse.Object.destroyAll(pears); //Destroy all pear objects.
}, function(error) {
  status.error("Failed to destroy all apples/pears.");
});

status.success("Successfully deleted " + results.length + " pears.");

Answer 1

你的status.success在destroyAll（梨）甚至有机会运行之前同步运行

以这种方式试试

Parse.Object.destroyAll(apples).then(function() {
    return Parse.Object.destroyAll(pears); //Destroy all pear objects.
}).then(function() {
    status.success("Successfully deleted " + results.length + " pears.");
}, function(error) {
    status.error("Failed to destroy all apples/pears.");
});
