I'm new to ArcGIS javascript API, now I want to create a feature layer and then add an array of attributes or simply update the array of attributes of a specific field. I only need to replace the original values array as my own array. Is that possible? There's a method: attr(name,value), Can I use this? Can any one give me some hints or code? Thanks in advance!
