Is it possible to retrieve all fields of a list (or default view) through the JavaScript Client Object Model and filter the fields on type (e.g. I only want the Choice fields).

 var clientContext = new SP.ClientContext.get_current(); var web = clientContext.get_web(); var list = web.get_lists().getByTitle(listName); var defaultview = list.getView('00000000-0000-0000-0000-000000000000'); this.listFields = defaultview.get_viewFields(); clientContext.executeQueryAsync(Function.createDelegate(this, this.onListFieldsQuerySucceeded), Function.createDelegate(this, this.onListFieldsQueryFailed)); function onListFieldsQuerySucceeded() { var fieldEnumerator = listFields.getEnumerator(); while (fieldEnumerator.moveNext()) { var oField = fieldEnumerator.get_current(); ... } }

Right now I'm getting following exception on listFields.getEnumerator()

Microsoft JScript runtime error: The collection has not been initialized. It has not been requested or the request has not been executed. It may need to be explicitly requested.

Same problem if I get the fields on the list directly.

  • Have you tried this.listFields.getEnumerator()? Commented Jan 5, 2012 at 13:01

You missed this line: clientContext.load(this.listFields); right after this.listFields = defaultview.get_viewFields(); , because your code not actually loads fields.

Complete code with field type checking looks like this one: 

var clientContext = new SP.ClientContext.get_current(); var web = clientContext.get_web(); var list = web.get_lists().getByTitle(listName); this.listFields = list.get_fields(); clientContext.load(this.listFields); clientContext.executeQueryAsync(Function.createDelegate(this, this.onListFieldsQuerySucceeded), Function.createDelegate(this, this.onListFieldsQueryFailed)); function onListFieldsQuerySucceeded() { var fieldEnumerator = listFields.getEnumerator(); while (fieldEnumerator.moveNext()) { var oField = fieldEnumerator.get_current(); var fType = oField.get_fieldTypeKind(); if(fType === SP.FieldType.choice) { ..... } } }

To verify field type you can use get_fieldTypeKind() or typeAsString() methods.

    and what about getting a specific listItem? Commented Feb 16, 2012 at 9:05
  • get_fieldTypeKind is not a function. Everthing goes good until this. Why please ? Commented Apr 7, 2016 at 13:40
