How to show multiple bookmarks in Google Map API v3?

Question

I cannot mark several points on the map. They could check if there is something wrong with the code?

var map;
var idInfoBoxAberto;
var infoBox = [];
var marker ;
var geocoder;

function initialize() {
    var latlng = new google.maps.LatLng(latitudes, longitudes);

    var options = {
        zoom: 14,
        center: latlng,
        mapTypeId: google.maps.MapTypeId.ROADMAP
    };

    map = new google.maps.Map(document.getElementById("mapa"), options);
    geocoder = new google.maps.Geocoder();

    for (var i = 0; i < coord.length; i++) {
        marker = new google.maps.Marker({
            position: new google.maps.LatLng(coord[i]),
            map: map,
        });
    }
}

initialize();

Being his array coord one string, the section you set the position of each marker is incorrect, since the class constructor google.maps.LatLng there must be at least two arguments, which is latitude and longitude (in this order), as defined in the variable latlng at the beginning of the function initialize().

Therefore, you first need to separate the values to define the values of latitude and longitude to then play in the property position in class options google.maps.Marker:

for (var i = 0; i < coord.length; i++) {
    var location = coord[i].split(",");

    var marker = new google.maps.Marker({
        position: new google.maps.LatLng(location[0], location[1]),
        map: map
    });
}
