javascript - 如何解析来自 Bigquery 结果的 json 响应？

Question

我尝试了示例 javascript 代码来调用 Google bigQuery API ( https://developers.google.com/bigquery/docs/authorization#client-side-javascript )

Js:

function runQuery() {
   var request = gapi.client.bigquery.jobs.query({
      'projectId': project_id,
      'timeoutMs': '30000',
      'query': 'SELECT TOP(repository_language, 5) as language, COUNT(*) as count FROM [publicdata:samples.github_timeline] WHERE repository_language != "";'
    });
    request.execute(function(response) {     
        console.log(response);
        var results = response.result.rows ;
        $('#result_box').html(JSON.stringify(results, null));
    });
}

上面的大查询返回:

[{"f":[{"v":"JavaScript"},{"v":"949899"}]},{"f":[{"v":"Ruby"},{"v":"640659"}]},{"f":[{"v":"Java"},{"v":"568202"}]},{"f":[{"v":"Python"},{"v":"484852"}]},{"f":[{"v":"PHP"},{"v":"453830"}]}]

请帮助我如何以 JSON 格式解析上述结果中的值？

{"JavaScript": "949899", "Ruby": "640659", "Java": "568202", "Python": "484852", "PHP": "453830" }

Eval 存在安全风险。

var text = '[{"f":[{"v":"JavaScript"},{"v":"949899"}]},{"f":[{"v":"Ruby"},{"v":"640659"}]},{"f":[{"v":"Java"},{"v":"568202"}]},{"f":[{"v":"Python"},{"v":"484852"}]},{"f":[{"v":"PHP"},{"v":"453830"}]}]';
myData = JSON.parse(text);
alert(myData[4].f[0].v);​
