[html] <!Doctype html> <html ng-app> <head> <script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/angularjs/1.0.1/angular.min.js"></script> <script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.8.1/jquery.min.js"></script> <script type="text/javascript"> […]
