CSOM – Stuff For SharePoint

In order to activate a feature via the client side we simply have to know the GUID of the feature.

If this is a site scoped feature this is pretty straight forward.

The following can be run from a script editor webpart;

	var featureCollection;
	var oneFeature;
	var site;
	var guid

	function findFeatureId() {
	var clientContext = new SP.ClientContext();
	site = clientContext.get_web();
	clientContext.load(site);
	featureCollection = site.get_features();
	clientContext.load(featureCollection);
	clientContext.executeQueryAsync(Function.createDelegate(this, this.onQuerySucceeded), Function.createDelegate(this, this.onQueryFailed));
	}
	function onQuerySucceeded() {
	var listEnumerator = featureCollection.getEnumerator();
	var featureInfo = '';
	while (listEnumerator.moveNext()) {
	oneFeature = listEnumerator.get_current();
	featureInfo += 'Feature ID: ' + oneFeature.get_definitionId() + '\n';
	guid = oneFeature.get_definitionId();
	}
	alert(featureInfo);
	}
	function onQueryFailed(sender, args) {
	alert('Request failed. ' + args.get_message() + '\n' + args.get_stackTrace());
	}

We can then use the GUID found with the next function

	function activateFeature(rawGuid){
	//get contextr of newly created site
	var clientContext = new SP.ClientContext($site_url);

	web = clientContext.get_web();

	//Activate Features
	ActivateWebFeature(web);
	function ActivateWebFeature(web){
	//trinedy branding feature GUID
	var guid = new SP.Guid('{'+rawGuid+'}');
	var featDefinition = web.get_features().add(guid, true, SP.FeatureDefinitionScope.farm);
	}
	}

This is especially useful when running with a function that manages site creation.
