Question

我需要更新存储在类中的多个对象的特定字段。我可以从客户端做到这一点，但我不喜欢它处理额外带宽的想法。如何更新和保存我在Cloud Code查询中迭代过的对象？基本上，什么是以下Swift方法的JS等价物？

var query = PFQuery(className:"GameScore")
query.whereKey("playerName", equalTo:"Sean Plott")
query.findObjectsInBackgroundWithBlock {
  (objects: [AnyObject]?, error: NSError?) -> Void in

  if error == nil {
    // The find succeeded.
    println("Successfully retrieved \(objects!.count) scores.")
    // Do something with the found objects
    if let objects = objects as? [PFObject] {
      for object in objects {
        // Update object here
      }

      // Save your changes to ALL objects
      PFObject.saveAllInBackground()
    }
  } else {
    // Log details of the failure
    println("Error: \(error!) \(error!.userInfo!)")
  }
}

我不确定你到底想要做什么，但也许这就是你要找的东西：

Parse.Cloud.define("updateScores", function(request, response) {
    var query = new Parse.Query("GameScore");
    query.equalTo("playerName", "Sean Plott");
    query.each(function (object) {
        // Do something with object
        object.save();
    }).then(function (success) {
        request.success("OK");
    }, function(err) {
        request.error(err);
    });
});

使用Parse Cloud Code一次更新多个对象
