Question

我必须从我的数据整理中获取检查点，这些检查点由objectId跟踪并匹配其中一个指针。我试过了。

var checkpoint = Parse.Object.extend("Checkpoint");
        var q1 = new Parse.Query(checkpoint);
        q1.equalTo("mission", {
            __type: "Pointer",
            className: "Mission",
            objectId: mid
        });
        q1.equalTo("checkpointType", {
            __type: "Pointer",
            className: "CheckpointType",
            objectId: "HJBdFD1p5f"
        })

        var q2 = new Parse.Query(checkpoint);
        q2.equalTo("mission", {
            __type: "Pointer",
            className: "Mission",
            objectId: mid
        });
        q2.equalTo("checkpointType", {
            __type: "Pointer",
            className: "CheckpointTYpe",
            objectId: "m17T0wLzwl"
        })

        var q3 = new Parse.Query(checkpoint);
        q3.equalTo("mission", {
            __type: "Pointer",
            className: "Mission",
            objectId: mid
        });
        q3.equalTo("checkpointType", {
            __type: "Pointer",
            className: "CheckpointTYpe",
            objectId: "mXPtoIRsI2"
        })

        var compquery = Parse.Query.or(q1,q2,q3);
        return compquery.find({
            success: function (results) {
                console.log(results);

            },
            error: function (results, error) {
                console.log(error);
            }
        });
    }

我有这个代码，它返回一个空数组。有没有办法完成这项工作？

此代码的问题是语法错误，

className: "CheckpointTYpe",

在所有查询中，

应为CheckpointType，但在我的代码中仅在第一次查询中

 var q2 = new Parse.Query(checkpoint);
    q2.equalTo("mission", {
        __type: "Pointer",
        className: "Mission",
        objectId: mid
    });
    q2.equalTo("checkpointType", {
        __type: "Pointer",
        className: "CheckpointType",
        objectId: "m17T0wLzwl"
    })

    var q3 = new Parse.Query(checkpoint);
    q3.equalTo("mission", {
        __type: "Pointer",
        className: "Mission",
        objectId: mid
    });
    q3.equalTo("checkpointType", {
        __type: "Pointer",
        className: "CheckpointType",
        objectId: "mXPtoIRsI2"
    })

    var compquery = Parse.Query.or(q1,q2,q3);
    return compquery.find({
        success: function (results) {
            console.log(results);

        },
        error: function (results, error) {
            console.log(error);
        }
    });
}

解析angularjs或AND或查询
