I had a bit of a "derrr" moment, today. When trying to set custom zoom
levels for markers (the value of which I pulled from an XML PHP MySQL
readout), I was trying to do this:
var zoomLevel = markers[i].getAttribute("zoomLevel");
map.setCenter(latlng, zoomLevel);
Much to my dismay, it was definitely not working. Replacing the
reference to zoomLevel like so:
map.setCenter(latlng, 13);
worked quite without fail.
After five minutes of head scratching, I remembered something I
learned when working with javascript last time. It tends to treat,
what would appear to be integers, as strings.
In order to make it work, I had to first perform a mathematical
operation on the string, to force javascript to recognise it as an
integer:
var zoomLevel = markers[i].getAttribute("zoomLevel");
zoomLevel = zoomLevel / 1;
map.setCenter(latlng, zoomLevel);
Just in case any other javascript noobs stumble across that little
annoyance.
