Best method of discovering the state

Question

I need to find out the status that the user is accessing the page, to select already be marked, and some functions enabled.

I was seeing that finding the status from the IP is pretty flawed. Ai saw that had to use the HTML5 Geolocation, however it only returns the latitude and longitude. Would somehow it return the state ?

I was looking for some function that would return the state, after informing the latitude and longitude, but did not find.

Does anyone know what I can do to precisely get what status the user is accessing ?

Answer 1

Using HTML5 and Oppenstreetmaps looks like this:

navigator.geolocation.getCurrentPosition(function(posicao) {
    var url = "http://nominatim.openstreetmap.org/reverse?lat="+posicao.coords.latitude+"&lon="+posicao.coords.longitude+"&format=json&json_callback=preencherDados";

    var script = document.createElement('script');
    script.src = url;
    document.body.appendChild(script);
});



function preencherDados(dados) {
  alert(dados.address.state);  
}
