Hey Team!
So, long story short, I'm creating an application that allows users to adopt road segments as the OOTB Esri option won't work for our needs. I've got to the point where users can click on the app, a form gets created and populated, they can input the necessary information, and apply the edits. However, as it stands, users can only select one feature at a time, which won't work.
I need users to be able to select multiple features on a map, fill out one form, and have the fields in the form be applied as unique edits to each of the selected features. The testing code block is below:
<!DOCTYPE html>

The way I've done it in my application (using JS 3.x) is to take a FeatureSet returned by the feature layer's selectFeatures method, run it through a loop to apply all the new attributes, and save those edits. I have a form where the user selects the attributes to be changed ('cboPriority', etc)
array.forEach(featureSet, function (feature) {
feature.attributes.Priority = registry.byId('cboPriority').get("value");
feature.attributes.Management = registry.byId('cboManagement').get("value");
feature.attributes.Criteria = registry.byId('cboCriteria').get("value");
});
layerFeatureLayer.applyEdits(null, featureSet, null, function () { console.log("Features updated!"); }, function (error) { console.log("Features not updated! ", error); });by

Is that application on github? I'd love to see how you accomplish this in the greater context of your application!

No, I haven't put it up on Github. The full site is here, but it requires an account to do the editing in the Prioritization tab.

n anyone had the sample code that should call applyEdits on a layer with multiple features in it. Thanks.
