Hi. Code not working because of async query and variable scope problem. I can't understand how to solve this. Change to $.ajax method with async:false - not an option. I know about closures, but how I can implement it here - don't know. I've seen all topics here about closures in js and jQuery async problems - but still nothing. Help, please.
Here is the code:
var map = null;
var marker;
var cluster = null;
function refreshMap()
{
var markers = [];
var markerImage = new google.maps.MarkerImage('/images/image-1_32_t.png', new google.maps.Size(32, 32));
$.get('/get_users.php',{},function(data){
if(data.status == 'error')
return false;
var users = data.users; // here users.length = 1 - this is ok;
for(var i in users)
{
//here I have every values from users - ok
var latLng = new google.maps.LatLng(users[i].lat, users[i].lng);
var mark = new google.maps.Marker({
position: latLng,
icon: markerImage
});
markers.push(mark);
alert(markers.length); // length 1
}
},'json');
alert(markers.length); // length 0
//if I have alert() above - I get result
cluster = new MarkerClusterer(map, markers,
{
maxZoom: null,
gridSize: null
});
}
Thanks.
