Passing location coordinates to google maps as variable

Anyone know why this will work:

var wickedLocation =  new google.maps.LatLng(44.767778, -93.2775);

But this won't:

var wickedCoords = "44.767778, -93.2775";
var wickedLocation =  new google.maps.LatLng(wickedCoords);

I tried passing the latitude and longitude as separate variables and that didn't do the trick either. How can I pass the coordinates successfully as a variable? Thanks!

If you are getting the coordinates as a string, in the format you showed in your example, you could do this:

var b=wickedCoords.split(",");
var wickedLocation=new google.maps.LatLng(parseFloat(b[0]), parseFloat(b[1]));

In this example, you are passing two distinct numerical values into a constructor and then assigning the newly created object to wickedLocation:

var wickedLocation =  new google.maps.LatLng(44.767778, -93.2775);

In this example, you're passing a single string value into a constructor that requires two distinct numerical coordinates:

var wickedCoords = "44.767778, -93.2775";
var wickedLocation =  new google.maps.LatLng(wickedCoords);

The data types are both completely different.

With that said, if you want to represent a coordinate as a single object, you can do so like this:

var myHome = { "lat" : "44.767778" , "long" : "-93.2775" };

var yourHome = { "lat" : "23,454545" , "long" : "-92.12121" };

Then when you need to create the coords object from Google, you can pass the data in as individual arguments derived from a single object:

var wickedLocation =  new google.maps.LatLng( myHome.lat, myHome.long );

I believe you can use strings to define the coordinates, but you need two (one for each parameter) not one.

wickedLat = '44.767778';
wickedLon = '-93.2775';
wickedLocation = new google.maps.LatLng(wickedLat, wickedLon);

If not either use floats directly or parse your strings into floats with parseFloat()
