如何从json输出中检索值

Question

我想从 console.log 的共享输出下面检索转录值。但只有具有另一个键的那个转录值需要是confidence 。

console.log 的输出：

  Data: {
    "results": [
    {
    "keywords_result": {
    "blocked": [
    {
    "normalized_text": "blocked",
    "start_time": 1.1,
    "confidence": 0.64,
    "end_time": 1.68
    }
    ]
    },
    "alternatives": [
    {
    "confidence": 0.81,
    "transcript": "your Name is Charlie "
    },
    {
    "transcript": "your Name is Charlie and "
    },
    {
    "transcript": "your Name is Charlies "
    }
    ],
    "final": true
    }
    ],
    "result_index": 0
    }
    Close: 1000

预期输出：

your Name is Charlie

请注意，我的预期值应该来自 console.log 输出到我可以进一步使用的变量。

Answer 1

你可以做这样的事情：

const confidenceObj = event.Data.results[0].alternatives.filter((ele)=>ele.confidence)
if(confidenceObj.length>0){console.log(confidenceObj[0].transcript);}

Answer 2

请参考以下代码。

 var jsonData = { "results": [{ "keywords_result": { "blocked": [{ "normalized_text": "blocked", "start_time": 1.1, "confidence": 0.64, "end_time": 1.68 }] }, "alternatives": [{ "confidence": 0.81, "transcript": "your Name is Charlie " }, { "transcript": "your Name is Charlie and " }, { "transcript": "your Name is Charlies " } ], "final": true }], "result_index": 0 }; for (var i = 0; i < jsonData.results[0].alternatives.length; i++) { if (jsonData.results[0].alternatives[i].confidence > 0) { console.log(jsonData.results[0].alternatives[i].transcript); } }
