【问题描述】：

在我的查询中，如何访问Parse 类中的对象？喜欢将对象awayTeam 设置为等于newAwayTeam 对象？

类似

CloseGameTime.set("awayTeam", "the newAwayTeam object");

原始代码

    Parse.Cloud.job("CloseGameTime", function(request, response) {
 
  Parse.Cloud.useMasterKey();
  
  var query = new Parse.Query("Score");

  query.first({
    success: function(CloseGameTime) {

    var newAwayTeamVar = request.object.get("newAwayTeam");

      CloseGameTime.set("isGameTime", "NO");
      CloseGameTime.set("awayTeam", newAwayTeamVar);


      CloseGameTime.save(null, {
        success: function(CloseGameTime) {
          response.success("Successfully updated the server.");
        },
        error: function(CloseGameTime, error) {
          response.error("Could not save changes to the server.");
        }
      });
    },
    error: function(error) {
      response.error("Could not find object.");
    }
  });
});

【解决方案1】：

不应该太难。我在解析云代码上做了类似的事情，所以试一试：

var awayTeamObject = request.object.get("newAwayTeam");
CloseGameTime.set("awayTeam", awayTeamObject);

这看起来是正确的，但是当我运行它时（参见上面的更新代码）我收到了这个错误Failed with: TypeError: Cannot call method 'get' of undefined

【解决方案2】：

我发现你只需要调用success函数，后面跟着.get。

var newAwayTeamVar = CloseGameTime.get("nextAwayTeam");

完整代码：

Parse.Cloud.job("CloseGameTime", function(request, response) {
 
  Parse.Cloud.useMasterKey();
  
  var query = new Parse.Query("Score");

  query.first({
    success: function(CloseGameTime) {

     var newAwayTeamVar = CloseGameTime.get("nextAwayTeam");


      CloseGameTime.set("isGameTime", "NO");
      CloseGameTime.set("awayTeam", newAwayTeamVar);
      CloseGameTime.set("nextAwayTeam", "");


      CloseGameTime.save(null, {
        success: function(CloseGameTime) {
          response.success("Successfully updated the server.");
        },
        error: function(CloseGameTime, error) {
          response.error("Could not save changes to the server.");
        }
      });
    },
    error: function(error) {
      response.error("Could not find object.");
    }
  });
});
