が$scope.myVar = 'https://www.w3schools.com';
のようにこれを試してみてください、とあなたが値を持っている必要があります。
var app = angular.module('myAngularApp', []);
var myController = app.controller('myController', MyController);
myController.$inject = ['$scope'];
function MyController($scope){
$scope.myVar = 'https://www.w3schools.com';
}
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<html>
<body ng-app="myAngularApp">
<div ng-controller = "myController">
<h1>Tutorials</h1>
<p>Go to <a ng-href="{{myVar}}">{{myVar}}</a> to learn!</p>
</div>
<p>This example could use the original href attribute, but in AngularJS, the ng-href attribute is safer.</p>
</body>
