    How do I use JSON.parse to get the value raw !?

  • Hi,

    If you use QML you can use JavaScript code:
    var obj = JSON.parser(json_string);
    console.log("raw: "+obj.results[0].raw);

    If you use C++ and Qt 5.x you can use QJsonDocument class:
    QVariantMap res = QJsonDocument::fromJson(json_str).toMap();
    qDebug()<<"raw: "<<res["results"].toList()[0].toMap()["raw"].toDouble();

    If you use C++ and Qt 4.x you need to use QJson lib from this "link":http://qjson.sourceforge.net.

  • thx :)
