[GIS] ArcGIS javascript API Update Records of a Feature Layer

arcgis-10.1arcgis-javascript-api

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!

i'd start by taking a look at the sample below, which demonstrates the use of a widget that simplifies the process of passing attribute edits back to ArcGIS Server.

if you aren't interested in using one of the APIs widgets, you can also make your own calls to featureLayer.applyEdits()

[GIS] Problem with identify task in ArcGIS JavaScript API 2.8

You have set up your identify parms to search in all layers with the following line of code.

identifyParams.layerOption = esri.tasks.IdentifyParameters.LAYER_OPTION_ALL

The identify task doesn't know which layers are visible in your map. In fact it doesn't even need that mapservice to be displayed in the map. And since you have set it to search in all layers, it wouldn't matter.

That's why you are getting results from all layers.

[GIS] Using update cursor on a field with a domain

It sounds like you need to get the coded value for Metre and calculate that coded value into the field, is that correct?

I've handled this with a dictionary before, but I created the coded-value domain myself with a dictionary (timezones below), so I already know the key: value pairs. So the trick is to, for a given value in the dict, get the key:

def get_timezone_key(timezone_val):
    """Get key value for a given timezone text value"""
    timezones = {1: "US/Alaska", 2: "US/Central", 3: "US/Eastern",
                 4: "US/Hawaii", 5: "US/Pacific"}
    # Get the subtype code from dict based on input def timezone user selected
    timezone_key = timezones.keys()[timezones.values().index(timezone_val)]
    return timezone_key

print get_timezone_key("US/Central") # gives 2

Please clarify if this is not what you are needing to accomplish.
