  function getListContentTypes() {
  var clientContext = new SP.ClientContext.get_current();
  if (clientContext != undefined && clientContext != null) {
   var web = clientContext.get_web();
  this.listCollection = web.get_lists();
  this.list = listCollection.getByTitle("List Request");
  this.contentTypeCollection = list.get_contentTypes();
  clientContext.load(this.contentTypeCollection);
  clientContext.executeQueryAsync(Function.createDelegate(this, this.onQuerySucceeded), Function.createDelegate(this, this.onQueryFailed));
  }
  }
 
  function onQuerySucceeded() {
  var contentType = 'List Content Types:\n '
  var contentTypeEnumerator = this.contentTypeCollection.getEnumerator();
  while (contentTypeEnumerator.moveNext()) {
  var content = contentTypeEnumerator.get_current();
  contentType += content.get_name() + '\n';
  }
  alert(contentType);
  }
 
  function onQueryFailed(sender, args) {
  alert('Request failed. ' + args.get_message() + '\n' + args.get_stackTrace());
  }</script>
  <input id="btnGetListContentTypes" onclick="getListContentTypes()" type="button"
