如何從此JSON數據中的第二個元素獲取第一個值？

我有2個集合FailedCount和SucceededCount的JSON。如何從此JSON數據中的第二個元素獲取第一個值？

{ 
"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 
    }] 
}

如何獲得第一個值SucceededCount？

我想：

jsonObj.SucceededCount[1];

但結果並不好：[object Object]。

使用jsonObj.SucceededCount [1] .SucceededCount_MEAS_VALUE –

'obj.SucceededCount [0] [ 「SucceededCount_MEAS_VALUE」]的屬性' – nicovank

**第一個**將會是索引0，而不是1，但是說了'[object Object]'是一個對象如何顯示爲一個字符串 –

試試這個

jsonObj.SucceededCount[0].SucceededCount_MEAS_VALUE;

希望這有助於。

以你的對象的屬性SucceededCount。你現在有一個數組。藉此陣列SucceededCount[0]的拳頭對象，然後選擇需要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);
