Question

I’m trying to generate a random location for a Marker on a google map. I have successfully managed to add the users latitude to a random number using parseFloat (when I simply + them it didnt work…).

However, I use the exact same code to parse the users longitude with a random number, and nothing happens.

E.g:

Latitude = 49.0291

Longitude = -0.9912

Both of these numbers are added to a number generated by (Math.floor(Math.random() * 300)/1000)

The latitude is randomly generated, and the marker moves accordingly. However, when I try to move that same marker vertically, nothing happens (despite the fact that the value does actually change!).

I have attached a JS FIDDLE of my code.

All help is greatly appreciated, thank you.

Instead of jamming a bunch of code into one line, I split it out and got it to work:

var newLat = parseFloat(geoplugin_latitude()) +  Math.floor(Math.random() * 300)/1000.0;
var newLng = parseFloat(geoplugin_longitude()) + Math.floor(Math.random() * 300)/1000.0;

Nesting functions in code is bad.
