It seems like you're mixing some things in the documentation of the Angular, I'll try to explain the problems:
This url you are using returns JSONP to bypass the access restriction policy to another domain. To receive data in this format, you must use the $http.jsonp method instead of $http.get .
According to the documentation for this method, the callback parameter of url must have the value JSON_CALLBACK , not herois as you are using. Otherwise the Angular will not know how to handle the result (if you want to keep your way, you would need to have a herois function that would handle the result).
The data returned by this URL looks like this:
{"name":"Super Hero","salutation":"Dia Duit","greeting":"Dia Duit Super Hero!"}
That is, it is an object, not an array. But the code in your view is treating it as if it were an array of objects, which would create a row in the table for each object with ng-repeat . This will not work with this data, you would need to eliminate the repeat and get the properties directly from the object.
Correcting these issues, your code would look like this:
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script><scripttype="text/javascript">
var app = angular.module('myApp', []);
app.controller('heroisCtrl', function($scope, $http) {
$http.jsonp("https://angularjs.org/greet.php?callback=JSON_CALLBACK&name=Super%20Hero")
.success(function(data) { $scope.dados = data;});
});
</script>
</head>
<body>
<div ng-app="myApp" ng-controller="heroisCtrl">
<table>
<tr>
<td>{{ dados.name }}</td>
<td>{{ dados.greeting }}</td>
</tr>
</table>
</div>
</body>
</html>
