For loop 循环中有许多删除的云代码，但response.success首先在parse.com上完成

我有一个查询，他们的查询可能会返回很多项。 我可以把它们全部检查一遍，然后摧毁它们

问题是因为destroy是异步的，所以response.success（）；部分在执行所有销毁之前执行，因此并非所有项目都被真正删除

我怎样才能让它等到循环完成后才响应。success（）

谢谢

garageQuery2.find({
              success: function(results) {
                alert("Successfully retrieved " + results.length + " garages to delete.");
                // Do something with the returned Parse.Object values
                for (var i = 0; i < results.length; i++) { 
                  var object = results[i];
                  object.destroy({
                      success: function(myObject) {
                        // The object was deleted from the Parse Cloud.
                      },
                      error: function(myObject, error) {
                        // The delete failed.
                        // error is a Parse.Error with an error code and description.
                      }
                    });
                }

                response.success();
              },
              error: function(error) {
                alert("Error: " + error.code + " " + error.message);
              }
            });

garageQuery2.find({
成功：功能（结果）{
警报（“已成功检索”+results.length+“要删除的车库”）；
//对返回的Parse.Object值执行一些操作
对于（var i=0；i

试着与承诺合作

此代码基于以下内容：

希望能有帮助

garageQuery2.find().then(function(results) {
  // Create a trivial resolved promise as a base case.
  var promiseSeries = Parse.Promise.as();
  // the "_" is given by declaring "var _ = require('underscore');" on the top of your module. You'll use Underscore JS library, natively supported by parse.com
  _.each(results, function(objToKill) {
    // For each item, extend the promise with a function to delete it.
    promiseSeries = promiseSeries.then(function() {
      // Return a promise that will be resolved when the delete is finished.
      return objToKill.destroy();
    });
  });
  return promiseSeries;

}).then(function() {
  // All items have been deleted, return to the client
  response.success();
});
