Question

Markers are showing correctly in Firefox, not in Chrome or Opera. I think i have some scope problem, as the db_locations array is ‘sometimes’ losing it’s value and is arriving empty to buildMap(). I said ‘sometimes’ because when i add alert(db_locations) in BuildMap() in the first page refresh ‘tends’ to show the actual values.

Appreciate any help.

var db_locations = new Array();
$.ajax({
    type: "GET",
    url: "markers_xml.php",
    dataType: "xml",
    success: function(xml) {
...
var inside = new Array(val1,val2,val3 etc);
db_locations[i]=inside;
...
});

function buildMap() { /* this is the init function */
...
setMarkers(map, db_locations);
...
}

function setMarkers(map, locations) {
// markers loop
}

window.onload = buildMap;

Most likely the AJAX request is not returning on time. Wrap the AJAX call in a function, call buildMap within the Ajax success function, and call the AJAX request wrapping function when the window loads.
