问题 There seems to be a bug where model data fetched from an http call is present in the $scope but not in a directive. Here is the code that illustrates the problem: Jsfiddle: http://jsfiddle.net/supercobra/hrgpc/ var myApp = angular.module('myApp', []).directive('prettyTag', function($interpolate) { return { restrict: 'E', link: function(scope, element, attrs) { var text = element.text(); //var text = attrs.ngModel; var e = $interpolate(text)(scope); var htmlText = "<b>" + e + "</b>"; element
