I have an Arduino Yun where I host a webpage. Now I want to display the wifi signal quality on that page. I managed to dig in the system and I am able to pop up this JSON-like-array array

Complex JSON-array

I have an Arduino Yun where I host a webpage. Now I want to display the wifi signal quality on that page. I managed to dig in the system and I am able to pop up this JSON-like-array

{ "conncount": 5, "leases": {  }, "wan": { "proto": "dhcp", "ipaddr": "192.168.0.13", "link": "/cgi-bin/luci/;stok=235c7aba0f5cbf5cf752ad119ece74e6/admin/network/network/lan", "netmask": "255.255.255.0", "gwaddr": "192.168.0.1", "expires": -1, "uptime": 4407, "ifname": "wlan0", "dns": [ "192.168.0.1" ] }, "membuffers": 15708, "connmax": 16384, "memfree": 1576, "uptime": 4481, "wifinets": [ { "device": "radio0", "networks": [ { "ifname": "wlan0", "encryption": "WPA2 PSK (CCMP)", "bssid": "04:A1:51:D3:BC:E8", "mode": "Client", "quality": 70, "noise": -95, "ssid": "Skynet-ITA", "link": "/cgi-bin/luci/;stok=235c7aba0f5cbf5cf752ad119ece74e6/admin/network/wireless/radio0.network1", "assoclist": { "04:A1:51:D3:BC:E8": { "rx_short_gi": true, "noise": -95, "rx_mcs": 7, "tx_40mhz": true, "rx_40mhz": true, "tx_rate": 135000, "tx_packets": 14825, "tx_short_gi": true, "rx_packets": 101935, "tx_mcs": 6, "inactive": 360, "rx_rate": 150000, "signal": -61 } }, "txpoweroff": 0, "bitrate": 135, "txpower": 16, "name": "Client \u0022Skynet-ITA\u0022", "channel": 6, "country": "NL", "signal": -61, "up": true, "frequency": "2.437" } ], "name": "Generic 802.11bgn Wireless Controller (radio0)", "up": true } ], "memtotal": 61116, "localtime": "Wed Feb  3 12:09:13 2016", "memcached": 17596, "loadavg": [ 0.04052734375, 0.125, 0.20263671875 ] }

Unfortunately, this is the way it comes and I can't change it nor do I know how it is produced.

Is there a way to extract the bit that says "Quality": 70?

I tried it with the following code but no luck (it came back as undefined). I used data[3] as it looks like multiple arrays and Quality is in the 4th one.

var q;

$(document).ready(function() {
var refresh = setInterval(getData, 5000);
});

function getData() {
$.ajax({
        type: "POST",
        url: "/cgi-bin/luci/;stok=6ea83154346f9c42e99ac14ae8856b2b?status=1&_=0.16447926725451678",
        dataType: "JSON",
        cahce: "false",
        success: function(data){
        q  = data[3].quality;
}
});
}
