I got an email from ESRI today showing how to add shapefiles, textfiles or GPS files to an ArcGIS.com map, including by drag+drop (details here if you missed it).
This looks great - can we do the same using the JS API directly?
The sample here shows how to use drag+drop but I'm more interested in the ability to load a local shapefile, using an Add Data methodology (so it'll work on IE and Safari).
Could we have a sample showing how to add a local shapefile to a JS API map?
