javascript - 无法使用 Parse 核心 javascript 按 objectId 更新行

Question

我无法在解析中按对象 ID 更新行。我正在使用解析javascript sdk。下面是我尝试过的代码，但无法将“read”列更新为 true。所以我的代码传入一个threadId和user对象来获取该线程下用户的所有评论。我想要做的是将所有评论标记为已读= true。我不确定为什么这段代码不起作用？知道如何更新我的行吗？

readAllById: function(threadId , user){ 

            var ParseString = Parse.Object.extend("Comments");
            var query = new Parse.Query(ParseString);
            query.equalTo("threadId", threadId);
            query.equalTo("user" , user);
            query.ascending("createdAt");
            query.include("user");
            query.include("item");
            return query.find().then(function(response){

                 for(var i = 0; i < response.length; i++ ) {

                    console.log(response[i]);
                  var object_id = response[i].id;
                  query.set("id", object_id);
                  query.set("read", true);
                  query.save();
                }

            }, function(error){
                //something went wrong!
            });

        },

好的。我通过使用下面的代码让它工作

 readAllById: function(threadId , user){ 

            var ParseString = Parse.Object.extend("Comments");
            var query = new Parse.Query(ParseString);
            query.equalTo("threadId", threadId);
            query.equalTo("user" , user);
            query.ascending("createdAt");
            query.include("user");
            query.include("item");
            return query.find().then(function(response){

                 for(var i = 0; i < response.length; i++ ) {

                   var result = Parse.Object.extend("Comments");

                    var result = new Parse.Query(result);
                    query.get(response[i].id,{
                        success: function(result) {
                            result.set('read', true);
                            result.save();
                        }
                    });

                }

            }, function(error){
                //something went wrong!
            });

        },
