Question

2つのコレクションFailedCountとSucceededCountを持つJSONがあります。最初の値SucceededCount取得方法

{ 
"FailedCount": [{ 
    "FailedCount_DATE_CURRENT_CHECK": "2016-11-30 10:40:09.0", 
    "FailedCount_DATE__CURRENT__CHECK": "10:40:09", 
    "FailedCount_MEAS_VALUE": 0 
    }, { 
    "FailedCount_DATE_CURRENT_CHECK": "2016-11-30 10:45:09.0", 
    "FailedCount_DATE__CURRENT__CHECK": "10:45:09", 
    "FailedCount_MEAS_VALUE": 0 
    }, { 
    "FailedCount_DATE_CURRENT_CHECK": "2016-11-30 10:50:09.0", 
    "FailedCount_DATE__CURRENT__CHECK": "10:50:09", 
    "FailedCount_MEAS_VALUE": 1 
    }], 
    "SucceededCount": [{ 
    "SucceededCount_MEAS_VALUE": 555 
    }, { 
    "SucceededCount_MEAS_VALUE": 547 
    }, { 
    "SucceededCount_MEAS_VALUE": 339 
    }] 
} 

？

は、私が試した：

jsonObj.SucceededCount[1]; 

しかし、結果は良好ではない：[object Object]。

Answer 1

この

jsonObj.SucceededCount[0].SucceededCount_MEAS_VALUE; 

を試してみてはこの情報がお役に立てば幸いです。

Answer 2

オブジェクトのプロパティSucceededCountを用意してください。今は配列があります。この配列SucceededCount[0]の拳オブジェクトを取り、その後、jsonObj.SucceededCountを使用し、あなたがSucceededCount[0].SucceededCount_MEAS_VALUE

var obj = { 
 
    "FailedCount": [{ 
 
    "FailedCount_DATE_CURRENT_CHECK": "2016-11-30 10:40:09.0", 
 
    "FailedCount_DATE__CURRENT__CHECK": "10:40:09", 
 
    "FailedCount_MEAS_VALUE": 0 
 
    }, { 
 
    "FailedCount_DATE_CURRENT_CHECK": "2016-11-30 10:45:09.0", 
 
    "FailedCount_DATE__CURRENT__CHECK": "10:45:09", 
 
    "FailedCount_MEAS_VALUE": 0 
 
    }, { 
 
    "FailedCount_DATE_CURRENT_CHECK": "2016-11-30 10:50:09.0", 
 
    "FailedCount_DATE__CURRENT__CHECK": "10:50:09", 
 
    "FailedCount_MEAS_VALUE": 1 
 
    }], 
 
    "SucceededCount": [{ 
 
    "SucceededCount_MEAS_VALUE": 555 
 
    }, { 
 
    "SucceededCount_MEAS_VALUE": 547 
 
    }, { 
 
    "SucceededCount_MEAS_VALUE": 339 
 
    }] 
 
}; 
 

 
console.log(obj.SucceededCount[0].SucceededCount_MEAS_VALUE);
