I'm new to AngularJS and I tried creating a sample login page and I tried routing to other page on successful login but nothing shows up in ng-view
and my code has no error. What could be the problem?
index.html
<html>
<head>
<script
src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.4/angular.min.js">
</script>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.4/angular-
route.js"></script>
<script src="maincontroller.js"></script>
</head>
<body>
<div ng-view>
</div>
</body>
</html>
controller
var app = angular.module('myapp', ['ngRoute']);
app.config(function($routeProvider) {
$routeProvider
.when('/', {
templateUrl: 'login.html',
controller: 'maincontroller'
})
.when('/dashboard', {
templateUrl: 'dashboard.html'
})
.otherwise('/', {
templateUrl: '/'
})
});
app.controller('maincontroller', function($scope, $location) {
$scope.submit = function($scope) {
var username = $scope.username;
var password = $scope.password;
if ($scope.username == 'ashok' && $scope.password == 'ashok') {
$location.path('/dashboard');
} else {
windows.alert('wrong stuff');
}
};
});
login.html
<div ng-controller="maincontrol">
<form action="/" name="formgroup">
<label>Username:<input type="text" id="username" ng-model="username"/></label><br>
<label>Password:<input type="password" id="password" ng-model="password"/></label><br>
<button type="button" ng-click="submit()">Login</button>
</form>
You should mention ng-app
in your HTML to make this an Angular app.
<html ng-app='myapp'>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.4/angular.min.js">
</script>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.4/angular-
route.js"></script>
<script src="script.js"></script>
</head>
<body>
<div ng-view>
</div>
</body>
</html>
Maincontroller.js
var app = angular.module('myapp', ['ngRoute']);
app.config(function($routeProvider) {
$routeProvider
.when('/', {
templateUrl: 'login.html',
controller: 'maincontroller'
})
.when('/dashboard', {
templateUrl: 'dashboard.html'
})
.otherwise('/', {
templateUrl: '/'
})
});
app.controller('maincontroller', function($scope, $location) {
$scope.submit = function() {
var username = $scope.username;
var password = $scope.password;
if ($scope.username == 'ashok' && $scope.password == 'ashok') {
$location.path('/dashboard');
} else {
windows.alert('wrong stuff');
}
};
});
$scope
is already injected in to the controller and you are passing that as a parameter to your submit function which is undefined
since you did not pass anything on submit.
Login.html
<form action="/" name="formgroup">
<label>Username:<input type="text" id="username" ng-model="username"/></label><br>
<label>Password:<input type="password" id="password" ng-model="password"/></label><br>
<button type="button" ng-click="submit()">Login</button>
</form>
Since you are injecting controller on routing, You don't have to use ng-controller
in your login.html
. It makes the controller execute again.
