Angular JS TypeError: f is not a function

You need to define callAtTimeout first then use it.

var callAtTimeout=function(){console.log("hi")}
$timeout(callAtTimeout,3000);

Initializations in Javascript are not hoisted.


You are defining the callAtTimeout function after it its call. You need to have it above it.

Working fiddle

Sample code:

(function () {

    var app = angular.module('Tutorial', []);
    app.controller("MyController", function ($scope, $timeout) {

        var callAtTimeout = function () {
            $scope.data = "hello";
        }
        $scope.data = "hi";
        $timeout(callAtTimeout, 3000);


 }); })();

You just need to re-arrange the order of your code, the definition for callAtTimeout function should be before you use it. Working example:

(function() {

  var app = angular.module('Tutorial', []);
app.controller("MyController",function($scope,$timeout){

    var callAtTimeout=function(){$scope.data="hello";}
    
    $scope.data="hi";
    $timeout(callAtTimeout,3000);

   
});
})();
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<body ng-app="Tutorial" ng-controller="MyController">  
     <input type="text" ng-model="data" />
</body>
