Javascript getting object properties

Question

I want to create a google.Visualization.DataTablein the end, to show a graph. By now, I have a Problem with the following:

This is my code for getting Object from JSON-string and listing Properties:

var jsonData = <?php echo "'". $jsonTable. "'"; ?>;
var parsed = JSON.parse(jsonData);

var sensors = [];

for (var x in parsed){
    sensors.push(parsed[x]);
}
var text ="";
for (var sensor in sensors){
    if (sensors.hasOwnProperty(sensor)){
        var measures = sensors[sensor];
        text += ('\r\n' + sensor);
        for (var time in measures){
            if(measures.hasOwnProperty(time)){
                text += ('\r\n' + time + " = " + measures[time]);
            }
        }
    }
}

$(document.getElementById('chart_div')).text(text);

And my jsonData looks like this:

    jsonData = '{"sensor1":
                  {"Date(2016,1,08,10,30,03)":19.187,
                   "Date(2016,1,08,10,00,02)":18.937[,...]},
                 "sensor2":
                  {"Date(2016,1,08,10,30,04)":18.687,
                   "Date(2016,1,08,10,00,03)":18.437[,...]}
                [,...]}'

My Problem is that i don't get the values "sensor1", "sensor2" and so on in the loop. text += ('\r\n' + sensor); only returns the index of the sensor-object in the sensors-object.

How can I get the sensor name instead of the index?

Answer 1

One simple workaround

Remove the var sensors = [];

Find sensors and replace with parsed.

Code:

for (var sensor in parsed){
if (parsed.hasOwnProperty(sensor)){
    var measures = parsed[sensor];
    text += ('\r\n' + sensor);
    console.log(parsed);
    for (var time in measures){
        if(measures.hasOwnProperty(time)){
            text += ('\r\n' + time + " = " + measures[time]);
        }
    }
}

How can I get the sensor name instead of the index?

You need to do something with the property name in your first loop.

At present you are taking the property name (sensor1), using it to get the value ({"Date...) and then putting the value in an array while discarding the property name.

The simplest option would be to get rid of your first loop entirely and work with parsed instead of sensors in your second loop.
