Here is my plunker:

You have to manually bootstrap them.
See :
Only one AngularJS application can be auto-bootstrapped per HTML document. The first ngApp found in the document will be used to define the root element to auto-bootstrap as an application http://docs.angularjs.org/api/ng.directive:ngApp

I'm learning Angular.js. I want to make a form where the user can see the output has they fill it out.
Here's test.html:
<head>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.0-rc.2/angular.js"></script>
<script src="test.js"></script>
</head>
<body ng-app="charter">
<div id="layout-wrapper" ng-controller="graphicLanguageCTRL">
<form id="graphic-language" ng-controller="graphicLanguageCTRL" novalidate>
<h3>Language</h3>
<input type="text" name="headline" placeholder="Headline" ng-model="graphic.hed"> <br>
</form>
</div>
<h1 class="graphic-title" ng-bind="graphic.hed"></h1>
</body>
Here's test.js:
var app= angular.module("charter",[]);
app.controller("graphicLanguageCTRL",function($scope){
$scope.master= {
hed: ''
};
});
I want the stuff typed into the input tag to be visible in the h1 tag. But when I type into the input tag, nothing appears in the h1 tag.
How do I fix this?
There are some errors in your code:
You are using ng-bind outside of controller
You are initializing graphicLanguageCTRL twice
In your script you are setting the wrong variable name
Below is the fixed code:
html
<body ng-app="charter">
<div id="layout-wrapper" ng-controller="graphicLanguageCTRL">
<form id="graphic-language" novalidate>
<h3>Language</h3>
<input type="text" name="headline" placeholder="Headline" ng-model="graphic.hed"> <br>
</form>
<h1 class="graphic-title" ng-bind="graphic.hed"></h1>
</div>
</body>
JS
var app = angular.module("charter",[]);
app.controller("graphicLanguageCTRL", function($scope){
$scope.graphic = {
hed : ''
};
});
var app = angular.module("charter",[]);
app.controller("graphicLanguageCTRL",function($scope){
$scope.graphic = {
hed: ''
};
});
or
var app = angular.module("charter",[]);
app.controller("graphicLanguageCTRL",function($scope){
$scope.graphic = {};
$scope.graphic.head = ''
});
2 things need to be taken care of:
Do not nest and use the same ng-controller
Move the h1 inside
the ng-controller block
Fixed version:
var app = angular.module('charter', []);
app.controller("graphicLanguageCTRL", function($scope) {
$scope.graphic = {
hed: ''
};
});

How to save data from the form by clicking on the button?
I do not understand where the error is.
As planned, when you click on the data from the field stored in the variable "master"
For example I use this tutorial: http://www.w3schools.com/angular/angular_forms.asp
<!DOCTYPE html>
<html lang="en">
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.4.8/angular.min.js"></script>
<body> <div ng-app="myApp" ng-controller="formCtrl">
<form novalidate>
First Name:<br>
<input type="text" ng-model="firstName"><br>
<button ng-click="copyData()">Click Me!</button>
</form>
<p>form = {{user}}</p>
<p>master = {{master}}</p>
</div>
<script>
var app = angular.module('myApp', []);
app.controller('formCtrl', function($scope) {
$scope.master = {uder.firstName};
$scope.reset = function() {
$scope.user = angular.copy($scope.master);
};
$scope.reset();
$scope.copyData=function(){
$scope.master1=angular.copy($scope.mas);
$scope.copyData();
}
});
</script>
</body>
</html>
First of all you have a typo error. Replace {uder.firstname} with {user.firstname}.
You should put some effort on understanding scopes and how you can use variables, that you declare on scopes.
You declare an input with ng-model="firstname", but on the controller you have a user object with the attribute firstname. You should change your form to:
<input type="text" ng-model="user.firstName"><br>
<button ng-click="reset()">RESET</button>
<button ng-click="copyData()">Click Me!</button>
and in your controller
app.controller('formCtrl', function($scope) {
$scope.user = { firstname:"", lastname:"" }; //init your user
$scope.master = user.firstname; //or user object itself, dont understand what exactly you would like to achieve
$scope.reset = function() {
$scope.user = $scope.master;
};
$scope.copyData=function(){ }//call your onclick event
//set the data, that you want directly here. Recursion will not work.
More information about scope and forms can definitely help you.
Firstly,There are some typos like $scope.mas and {uder.firstname}.
Inspite of that you are assigning a property to the $scope object using ng-model directive but in the controller you are trying to access it using an object called user which would be undefined at this point.Here is the change in your code
First Name:<br>
<input type="text" ng-model="user.firstName"><br>
<button ng-click="reset()">
RESET</button>
<button ng-click="copyData()">
Click Me!</button>
</form>
<p>
form = {{user}}</p>
<p>
master = {{master}}</p>
The controller would be like
$scope.reset = function() {
$scope.user = angular.copy($scope.master);
};
$scope.reset();
$scope.copyData = function () {
$scope.master = user.firstName;
$scope.master1=angular.copy($scope.master);
$scope.copyData();
};
Thanks to all!
A working version:
(function(angular) {
'use strict';
angular.module('scopeExample', [])
.controller('MyController', ['$scope', function($scope) {
$scope.username = 'World';
$scope.sayHello = function() {
$scope.greeting = 'Hello ' + $scope.username + '!';
};
}]);
})(window.angular);

I am having troubles with using ng-click. I have added ng-click directive to the button. It does not trigger the function associated with ng-click. In Angular Batarang tool, it says the functions are undefined.
I tried the problem in Plunker.It does work. And also If i hard code the file path it works.
index.html code
<!DOCTYPE html>
<HTML ng-app="myEventApp">
<head>
<meta charset="UTF-8">
</head>
<body>
<h1 ng-controller="HelloWorldController">{{ helloMessage }}</h1>
<div ng-controller="EventDetail">

<div ng-include="" src="fileName"></div>
<!--<ng-include src="fileName"></ng-include>-->
<!--<div ng-include="" src="'template/testing10000.html'"></div>-->
<button ng-click=incrementCounter()>Next</button>
<button ng-click=decrementCounter()>Back</button>
<script
src="https://cdnjs.cloudflare.com/ajax/libs/angular.js/1.5.0/angular.js"></script>
<script src="js/app.js"> </script>
</body>
</HTML>
app.js code
var app = angular.module("myEventApp", []);
app.controller('HelloWorldController', ['$scope', function($scope){
$scope.helloMessage = "Book Viewer";
}]);
app.controller('EventDetail', ['$scope', function($scope){
$scope.counter = 0;
$scope.fileName = 'template/testing1000'+$scope.counter+'.html';
$scope.incrementCounter = function(){
$scope.counter++;
$scope.fileName = 'template/testing1000'+$scope.counter+'.html';
console.log($scope.counter);
}
$scope.decrementCounter = function(){
$scope.counter--;
$scope.fileName = 'template/testing1000'+$scope.counter+'.html';
console.log($scope.counter);
}
}]);
You declared the functions inside the EventDetail controller, but you have the buttons outside of the controller container in the html.
<div ng-controller="EventDetail">
<div ng-include="" src="fileName"></div>
<button ng-click="incrementCounter()">Next</button>
<button ng-click="decrementCounter()">Back</button>
</div>
I have an application where a part of the page is implemented in angular js. I have a requirement where I have to reload the angular js template coming from the server, based on some user action. I have simulated the exact situation with a dummy code,
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.0.2/jquery.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.7/angular.min.js"></script>
<script type="text/javascript">
var angApp = angular.module("app", []);
angApp.controller("mainCtrl", function($scope){
$scope.p1 = "Hello1";
$scope.p2 = "Hello2";
})
angular.element(document).ready(function() {
angular.bootstrap(document, ['app']);
});
function add(){
var tpl = "<div>{{p1}}</div><div>{{p2}}</div>";
$("#container").html("");
$("#container").html(tpl);
angular.element(document).injector().invoke(function($compile){
var obj=$('#angApp');
var scope = angular.element($("#angApp")).scope();
$compile(obj.contents())(scope);
scope.$digest();
});
var angControllerScope = angular.element($("#angApp")).scope();
angControllerScope.$apply(function() {
angControllerScope.p1 = "New Hello";
});
}
</script>
<body>
<button type="button" onclick="add()">Add</button>
<div id="angApp" ng-controller="mainCtrl">
<div id="container">
<div>{{p1}}</div>
<div>{{p2}}</div>
</div>
</div>
</body>
On click of Add button how to get the value as "Hello" again.
Thanks.
Sorry if i have misunderstood what you mean but this is what i think you are trying to achieve...
var app = angular.module('app', []);
app.controller('mainController', function($scope) {
$scope.p1 = 'Hello';
$scope.add = function() {
$scope.p1 = 'New Hello'
}
});

<div class="container" ng-controller="mainController">
<button type="button" ng-click="add()">Add</button>
{{p1}}
</div>
</body>
</html>
Found the solution. I had to recompile the template so that the binding with controller again works fine. Below link was useful.

I have updated the initial code with the working version.
Im basic developer , just wanted to pass hidden values from my html page in a json array . Following is my code :-
Index.html
<!doctype html>
<html ng-app="plunker" >
<head>
<meta charset="utf-8">
<title>AngularJS Plunker</title>
<script>document.write('<base href="' + document.location + '" />');
</script>
<link rel="stylesheet" href="style.css">
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.0.5/angular.js"></script>
<script src="app.js"></script>
</head>
<body>
<div ng-controller="WorkingCtrl">
<h1 ng-bind="vm.heading"></h1>
<form name="myForm" novalidate>
<b> Text: </b>
<input ng-model="form.text" required /><br>
<button ng-click="submitForm()" bng-disabled="myForm.$invalid">Click Me!</button>
</form>
<p ng-bind="showValues"></p>
</div>
</body>
</html>
app.js
var app = angular.module('myApp');
app.controller('WorkingCtrl', ['$scope', '$http', function ($scope, $http) {
$scope.form = {};
$scope.submitForm = function () {
$scope.showValues = JSON.stringify($scope.form);
}
}]);
Now , the value from ng-model="form.text" successfully returns the result as for unhidden input types
{ "text":"What_ever_text" }
but how to send a defined value in array, consisting of hidden input type like :-
<input value="99999" type="hidden" ng-model="form.userid" required />
So , wanted desired output like :-
{ "text":"What_ever_text" , "userid":"99999" }
any solution ?
Note :- The input type should be hidden or any other easier method appreciated. Thanks in advance.
hidden input fields also works same as normal fields only.
see the below code
var app = angular.module('myApp', []);
app.controller('WorkingCtrl', ['$scope', '$http', function ($scope, $http) {
$scope.form = {
text: "some test",
userid: '12312312312'
};
$scope.submitForm = function () {
$scope.showValues = JSON.stringify($scope.form);
}
}]);
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="myApp">
<div ng-controller="WorkingCtrl">
<h1 ng-bind="vm.heading"></h1>
<form name="myForm" ng-submit="submitForm()" novalidate>Text:
<input ng-model="form.text" required />
<br/>
<input type="hidden" ng-model="form.userid" required />
<button bng-disabled="myForm.$invalid">Click Me!</button>
</form>
<p ng-bind="showValues"></p>
</div>
</div>
