Basic function in AngularJS
发布于 2020-03-27 15:41:12
I'm trying to write a simple "Hello World" application with AngularJS.
I would expect the function greeting() to print the name inserted in the text input in real time, but instead I get simply {{greeting()}} in output. What's wrong?
<!doctype html>
<body ng-app="myApp">
<div ng-controller="userController">
<p>Name: <input type="text" ng-model="user.name"></p>
<p>Surname: <input type="text" ng-model="user.surname"></p>
<p>{{greeting()}}</p>
</div>
<script type="text/javascript">
angular.module("myApp", [])
.controller("userController",
function ($scope) {
$scope.user = {name: "Mario", surname: "Rossi"};
$scope.greeting = function() {
return "Hello " +
$scope.user.name + " " +
$scope.user.surname + "!"
};
});
</script>
</body>
</html>
Here's an example: I would like to see Hello John Smith! instead of {{greeting()}}.
