选择JSON结果

Question

我正在使用WifiWizard来扫描当前网络。为此，我使用以下

    WifiWizard.startScan(success, fail);

    function success()
    {
    WifiWizard.getScanResults(networks,fail);   
    }

    function fail()
    {
    alert('not found');
    }    

    function networks(networkResult)
    {
    result =(JSON.stringify(networkResult));
    alert(JSON.stringify(networkResult));
    }

这确实为我提供了像这样的网络结果

networks = [
{   "level": signal_level, // raw RSSI value
    "SSID": ssid, // SSID as string, with escaped double quotes: "\"ssid name\""
    "BSSID": bssid // MAC address of WiFi router as string
    "frequency": frequency of the access point channel in MHz
    "capabilities": capabilities // Describes the authentication, key management, and encryption schemes supported by the access point.
    "timestamp": timestamp in microseconds (since boot) when this result was last seen.
}
]

但我只想要BSSID，我认为这将是networkResult.BSSID，但这是未定义的。我如何获得BSSID＆gt;

Answer 1

networkResult变量是一个数组，因此您需要它的第一个元素：

networkResult[0]['BSSID']

或

networkResult[0].BSSID
