I'm using Google Maps API v3 and need to offset markers based on the
current zoom level.
I have a global variable current_zoom_level, and an event listener for
zoom in/out:
google.maps.event.addListener(map, 'zoom_changed', function() {
current_zoom_level = map.getZoom(); alert(current_zoom_level); });
I've tried this bit in the initialization code and the code that
calculates the offset. The alert displays the correct current zoom
level, but when I access it in build_loan_markers() (where I calculate
offsets) current_zoom_level is undefined.
function build_loan_markers () {
var offset; alert(current_zoom_level); if(!window.current_zoom_level){
window.current_zoom_level = 1; } offset =
1/(window.current_zoom_level^2); alert('zoom: ' + current_zoom_level
+ ' offset: ' + offset); etc.. }
How can I globally set this variable?
Thank you!
