OK, I have a simple cancer web map in Leaflet and I'm stumped on a problem.
1. I have an HTML check box which when clicked turns on a layer. (Layer switcher is not an option) this basically calls a function and passes the cancer layer name. i.e.updateLayerVis("lung")
2. I have different types of cancer defined by name. i.e. var throat = new L.GeoJSON(data .....
3. So the function listed above passes the value 'lung' to 'a' below. It appears to be passing a dumb string called 'lung' while addTo is looking for a layer. Is it possible to use this string to add the appropriate layer to the map?
console.log(a); // lung
a.value.addTo(map); // returns an error "a.addTo is not a function"
a.addTo(map); // returns an error "a.addTo is not a function"
lung.addTo(map); //works but with 15 check boxes, I'd need a large switch function.
