accessing fields with periods in field names

[DennisAkins]

I issue a query from a layer in my map service that has a join to a table in SQLServer.  Typically I can get the value by using a construct such as 'result.features[0].attribute.fieldID'  However, the field names in the joined table have names such as "dbasename.user.fieldname"  If I use the periods in my previous construct like 'result.features[0].attribute.dbasename.user.fieldID' it of course will not run. 

What is a quick and easy way to get around the dots in the field names?

Try this instead:

result.features[0].attributes['dbasename.user.fieldID']
