Access Basemap Value

ChrisSeeger

I would like to access and reset the value for the basemap and zoom via a javascript form field. my question is how to I access these. I am able to acces the map width but not these three items.

function init() {
      map = new esri.Map("map", {
        center: [-31.036, 42.747],
        zoom: 8,
        basemap: "streets"
      });

Found this in the whats new at 3.3
Two new map methods, getBasemap and setBasemap, make switching basemaps easy. setBasemap accepts one of the strings mentioned....

Cool, that looks much easier.

  function init() {
   map = new esri.Map("map", {
   center: [-31.036, 42.747],
   zoom: 8,
   basemap: "streets"
      });

You can get to the array of basemaps using map.basemapLayerIds, so the first basemap will be map.basemapLayerIds[0]

map.getZoom() will return the zoom level while map.setZoom(10) will set the level.

Cheers,
Steve
