I am attempting to update a list outside of my app web. When I find the list, I am finding my column, then casting that into a TaxonomyField. The purpose of casting is to be able to play with
get_termGuid() which would then let me get to
The following works just fine, but I'm not getting the results that I am expecting.
myField.get_typeDisplayName() gives me 'Managed Metadata'
taxFieldValue.get_termGuid() gives me "". So when I attempt to load taxFieldValue, I get
'Object doesn't support property or method 'get_$19_0''
Something seems off, what am I missing here? Most of the samples that I have seen out there are for getting the value of a specific list item. What I am trying to do is alter the Term Store Settings for a specific list column. Not seeing too much out there on that.
var appweburl = decodeURIComponent(getQueryStringParameter("SPAppWebUrl")); var clientContext = new SP.ClientContext.get_current(); var hostweburl = decodeURIComponent(getQueryStringParameter("SPHostUrl")); siteUrl = hostweburl + '/' + url; var hostcontext = new SP.AppContextSite(clientContext, siteUrl); oWeb = hostcontext.get_web(); oList = oWeb.get_lists().getByTitle(title); listFields = oList.get_fields(); myField = listFields.getByInternalNameOrTitle("ACKeyWord"); taxField = clientContext.castTo(myField, SP.Taxonomy.TaxonomyField); taxFieldValue = taxField.getFieldValueAsTaxonomyFieldValue(); clientContext.load(oList); clientContext.load(myField); clientContext.load(taxField); clientContext.executeQueryAsync(Function.createDelegate(this, onListFieldsSucceeded), Function.createDelegate(this, onListFieldsFailed));
