Thank you for the help. I assume I did this incorrectly since it's not
zooming in when I search (longwood, fl, 5mi for example).
Here is my code:
function searchLocationsNear(center) {
clearLocations();
var radius = document.getElementById('radiusSelect').value;
var searchUrl = 'phpsqlsearch_genxml.php?lat=' + center.lat() +
'&lng=' + center.lng() + '&radius=' + radius;
downloadUrl(searchUrl, function(data) {
var xml = parseXml(data);
var markerNodes = xml.documentElement.getElementsByTagName("marker");
var bounds = new google.maps.LatLngBounds();
sidebarInfo = ""; //this clears the list in the sidebar with each
search
var visibleMarkersCount=0;
if (markerNodes[0].getAttribute("street")=="No properties found"){
map.setZoom(8);
}
for (var i = 0; i < markerNodes.length; i++) {
var id = markerNodes[i].getAttribute("property_id");
var city_id = markerNodes[i].getAttribute("city");
var state_id = markerNodes[i].getAttribute("state");
var country_id = markerNodes[i].getAttribute("country");
var postal_code = markerNodes[i].getAttribute("postal_code");
var address = markerNodes[i].getAttribute("street");
var price = markerNodes[i].getAttribute("price");
var bedrooms = markerNodes[i].getAttribute("bedrooms");
var bathrooms = markerNodes[i].getAttribute("bathrooms");
var category_id = markerNodes[i].getAttribute("type");
var living_area = markerNodes[i].getAttribute("sqft");
var lot_area = markerNodes[i].getAttribute("lotsqft");
var listing_type_id = markerNodes[i].getAttribute("listing");
var building_name = markerNodes[i].getAttribute("building_name");
var distance = parseFloat(markerNodes[i].getAttribute("distance"));
var googlemap_ltgooglemap_ln = new google.maps.LatLng(
parseFloat(markerNodes[i].getAttribute("googlemap_lt")),
parseFloat(markerNodes[i].getAttribute("googlemap_ln")));
createOption(address, distance, i+1);
createMarker(googlemap_ltgooglemap_ln, address, city_id, state_id,
country_id, postal_code, price, bedrooms, bathrooms, category_id,
living_area, lot_area, building_name, listing_type_id, id);
bounds.extend(googlemap_ltgooglemap_ln);
visibleMarkersCount++;
}
switch(visibleMarkersCount){
case 0:
// no markers have been created
// set map zoom and center accordingly - or just it leave it as it
is
map.setZoom(8);
break;
case 1:
// a single marker has been created
// center on the marker but set a zoom level that's not fully
zoomed in
map.setZoom(8);
break;
default:
// two or more markers have been created
// fit the map to the markers
map.fitBounds(bounds);
}
map.fitBounds(bounds);
//map.setZoom(8);
/*locationSelect.style.visibility = "visible";
locationSelect.onchange = function() {
var markerNum =
locationSelect.options[locationSelect.selectedIndex].value;
google.maps.event.trigger(markers[markerNum], 'click');
};*/
});
}
The commented out map.setZoom(8); (8 lines from the bottom) set the zoom of
the map on search, but didn't zoom out when there were more than one
properties (if that made sense).
What did I do wrong?
Thank you for the help.
