Create Javascript Object

I have this function // add history paths and save data function AddPath( strTag, strUserName, arrayLatLngPoints, pathColour) { for (var i = 0; i < arrayLatLngPoints.length;

Solution 1:

How can i create this object?

Pretty much exactly like you did:

varobj= { strUserName : { timestamp :point.timestamp , LatLng :point.LatLng }, strUserName : { timestamp :point.timestamp , LatLng :point.LatLng } };

Or more readably:

varobj= {
    strUserName : {
        timestamp :point.timestamp ,
        LatLng :point.LatLng
    },
    strUserName : {
        timestamp :point.timestamp ,
        LatLng :point.LatLng
    }
};

That's an object initializer. It creates a new object with the given properties (actually, three new objects) and returns a reference to the outermost of them.

Taking some simpler examples:

// Create a blank object (an objectwith no properties of its own):
var a = {};

// Create an objectwith a `name` propertywith the value "Fred"
var b = {name: "Fred"};

// Create an objectwith a `foo` property, which is *another* freshly-created
// objectwith a `name` propertywith the value "Barney"
var c = {
    foo: {
        name: "Barney"
    }
};

Re your updated question:

the username has not worked and im not getting an item for each timestamp, its just overwriting the one entry?

Of course it is, you're overwriting history on each loop, without storing the earlier copy anywhere. For instance, you can store them in an array:

// add history paths and save datafunctionAddPath( strTag, strUserName, arrayLatLngPoints, pathColour) {

  var historyArray = [];
  for (var i = 0; i < arrayLatLngPoints.length; i++)
    {
    var point = arrayLatLngPoints[i];
    var pos = new google.maps.LatLng(point.lat, point.lng);

    historyArray[i] = {
        strUserName : {
            timestamp : point.timestamp ,
            LatLng : pos
        }
    };

    var date = newDate( parseInt( point.timestamp));
    addMarkers(point.timestamp, point.lat, point.lng, point.timestamp, strUserName, pathColour, date.toString());
    date = null; 
    }
console.log(historyArray);
}

Solution 2:

varobj= {strUserName: {timestamp:point.timestamp, lat:point.lat, long:point.long}}
