Angularjs not binding data and html not printing scope variables

Question

That's my complete code angular is not printing vars in the body tag of the html pice, console.log() everywhere is working. ng-click at submit button is also working.

<html ng-app="fb">

<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap      /3.3.7/css/bootstrap.min.css"
 integrity="sha384-   BVYiiSIFeK1dGmJRAkycuHAHRg32OmUcww7on3RYdg4Va+PmSTsz/K68vbdEjh4u" 
crossorigin="anonymous">

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.5  /angular.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.4/angular-route.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/angular-cookie/4.1.0/angular-cookie.js"></script>

<script>
var app=angular.module('fb', []);

app.controller('home',function($scope){
    var hi;
    $scope.hi=5;
    //$rootScope.hola=9;
    console.log($scope.hi);
    //console.log($rootScope.hola);

    $scope.submitSignup=function()
    {
    var hi;
    $scope.hi=5;
    //$rootScope.hola=9;
    console.log($scope.hi);
    //console.log($rootScope.hola);
    console.log($scope.username);
        alert('button pressed');
    };
});

</script>
<head>
<title>Index</title
</head>

<body>
<div ng-controller='home'>
<input type="text" placeholder="Username" ng-model="username">
<br>
<input type="password" placeholder="Password" ng-model="password">
<br>

<button type="button" ng-click="submitSignup()">SignUp</button>

<br>

<p> {{username}} </p>


<p> {{hi}} </p>


{{hola}}


</div>

<p> index </p>
</body>
</html>

Scratching my head for hours and hours at this, any help will be appreciated.

add ng-app in your template with ng-app="fb"

DEMO

<html ng-app="fb">
<head>
<title>Index</title>
</head>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.5/angular.min.js"></script>
<script>
var app=angular.module('fb', []);
app.controller('home',function($scope){
    var hi;
    $scope.hi=5;
    //$rootScope.hola=9;
    console.log($scope.hi);
    //console.log($rootScope.hola);

    $scope.submitSignup=function()
    {
    var hi;
    $scope.hi=5;
    //$rootScope.hola=9;
    console.log($scope.hi);
    //console.log($rootScope.hola);
    console.log($scope.username);
        alert('button pressed');
    };
});
</script>
<body>
<div ng-controller='home'>
<input type="text" placeholder="Username" ng-model="username">
<br>
<input type="password" placeholder="Password" ng-model="password">
<br>
<button type="button" ng-click="submitSignup()">SignUp</button>
<br>
<p> {{username}} </p>
<p> {{hi}} </p>
{{hola}}
</div>
<p> index </p>
</body>
</html>

ng-app="fb" is added above all sources in the <html> tag.

Sajeetharan Over a year ago

did you check the demo? in your html there is no reference for angular and script

Asim Over a year ago

These are the links I have added, ng-click works so angular does work. <link rel="stylesheet" href="maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" integrity="sha384-BVYiiSIFeK1dGmJRAkycuHAHRg32OmUcww7on3RYdg4Va+PmSTsz/K68vbdEjh4u" crossorigin="anonymous"> <script src="ajax.googleapis.com/ajax/libs/angularjs/1.6.5/…> <script src="ajax.googleapis.com/ajax/libs/angularjs/1.6.4/…> <script src="cdnjs.cloudflare.com/ajax/libs/angular-cookie/4.1.0/…>

where is the reference for your controller and module script

Asim Over a year ago

they are in the same file so maybe no reference needed?

You forgot to initiate your app with ng-app="fb"

 <body ng-app="fb">
    <div ng-controller="home">
        <input type="text" placeholder="Username" ng-model="username">
        <br>
        <input type="password" placeholder="Password" ng-model="password">
        <br>
        <button type="button" ng-click="submitSignup()">SignUp</button>

        <p> {{username}} </p>

        <p> {{hi}} </p>

        {{hola}}

    </div>
    <p> index </p>
</body>

</html>

Show your files which are loaded in ur above html

Asim Over a year ago

These are the links I had from angular's documentation. Angular is working, but data is not being displayed also ng-click does calls my function and generates alert.

Try to abstract your angular code into a js and give the reference to that js file in your above html

Asim Over a year ago

that space was added maybe while posting, its not in my source code. Okay going to put it in js file. But it should work this way.
