A simplified version of the code:
<!DOCTYPE html>
<html ng-app="main">
<head>
<meta charset="UTF-8">
<title></title>
<script type="text/javascript" src="https://code.angularjs.org/1.4.3/angular.min.js"></script>
<script>
var app = angular.module("main", []);
app.controller("TestController", function($scope) {
$scope.addresses = [{street: ""}, {street: ""}];
$scope.next = function() {
if ($scope.addressMainForm.addressForm.$valid) {
console.log("valid");
} else {
console.log("invalid");
}
$scope.addresses.push({street: ""});
};
$scope.remove = function(index) {
$scope.addresses.splice(index, 1);
};
});
</script>
</head>
<body>
<div ng-controller="TestController" style="width: 500px;">
<form name="addressMainForm">
<div ng-repeat="address in addresses">
<ng-form name="addressForm">
<input ng-model="address.street" required name="street" type="text" placeholder="street" />
<button ng-if="$index > 0" ng-click="remove($index)">REMOVE</button>
</ng-form>
<br>
</div>
</form>
<br>
<button ng-click="next()">NEXT</button>
</div>
</body>
</html>
which looks in the browser like this:
When I click "REMOVE" and then "NEXT" - javascript error is produced:
Error: $scope.addressMainForm.addressForm is undefined
Why is it undefined if there is clearly still one element remaining in the array? Everything otherwise works fine (console.log output), until all the elements are removed but the last one and "NEXT" is clicked.
When you call $scope.addressMainForm.addressForm.$valid , you are attempting to call check to see if the adressForm element is valid, but your remove function has removed the addresses entry associated with that element. So the form indeed still exists, but that call becomes illegal.
Try this:
<!DOCTYPE html>
<html ng-app="main">
<head>
<meta charset="UTF-8">
<title></title>
<script type="text/javascript" src="https://code.angularjs.org/1.4.3/angular.min.js"></script>
<script>
var app = angular.module("main", []);
app.controller("TestController", function($scope) {
$scope.addresses = [{street: ""}, {street: ""}];
$scope.next = function() {
if ($scope.addressMainForm.$valid) {
console.log("valid");
} else {
console.log("invalid");
}
$scope.addresses.push({street: ""});
};
$scope.remove = function(index) {
$scope.addresses.splice(index, 1);
};
});
</script>
</head>
<body>
<div ng-controller="TestController" style="width: 500px;">
<form name="addressMainForm">
<div ng-repeat="address in addresses">
<ng-form name="addressForm">
<input ng-model="address.street" required name="street" type="text" placeholder="street" />
<button ng-if="$index > 0" ng-click="remove($index)">REMOVE</button>
</ng-form>
<br>
</div>
</form>
<br>
<button ng-click="next()">NEXT</button>
</div>
</body>

i've been stuck here for a while, when i'm using "form" tag everything is ok but in "div" tag ...
main.js:
var app = angular.module('demo', []);
app.controller('appctrl', function ($scope) {
$scope.start = function (name) {
console.log(name);}
}
index.html:
<!DOCTYPE html>
<html ng-app="demo">
<head>
<script src="js/angular.min.js"></script>
<script src="js/main.js"></script>
</head>
<body>
<div id="container" ng-controller="appctrl">
<input id="input" autocorrect="off" spellcheck="false" autocapitalize="off" autofocus="true" placeholder="Please enter your full name" type="text" ng-model="name">
<div id="button" ng-click="show()">Start Demo</div>
</div>
</body>
</html>
I think you need this, you need to name the function as show , also you need to pass parameter to the function show.
additionaly you are missing ) in your controller.
app.controller('appctrl', function ($scope) {
$scope.show = function (name) {
console.log(name);}
}
DEMO
var app = angular.module('demo', []);
app.controller('appctrl', function ($scope) {
$scope.start = function (name) {
console.log(name);
}
});
<!DOCTYPE html>
<html ng-app="demo">
<head>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.5.5/angular.min.js"></script>
</head>
<body>
<div id="container" ng-controller="appctrl">
<input id="input" autocorrect="off" spellcheck="false" autocapitalize="off" autofocus="true" placeholder="Please enter your full name" type="text" ng-model="name">
<div id="button" ng-click="start('TEST')">Start Demo</div>
</div>
</body>
</html>
app.controller('appctrl', function ($scope) {
$scope.name = null;
$scope.show = function (name) {
console.log(name);
}
});
<div id="container" ng-controller="appctrl">
<input id="input" autocorrect="off" spellcheck="false" autocapitalize="off" autofocus="true" placeholder="Please enter your full name" type="text" ng-model="name">
<div id="button" ng-click="show(name)">Start Demo</div>
</div>
You're calling show() but you defined start()

So many mistakes. This is just sample. You should use $route (ng-view or ui-view) for route navigation.. I was updated plnkr.

I have angularjs front end code as follows:
function addController($scope, $http) {
$scope.tableNames = [];
$scope.addNewColumn = function(item) {
$scope.tableNames.push({})
}
}
<html ng-app>
<head>
<title></title>
<meta charset="utf-8" />
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.6/angular.min.js"></script>
<link rel="stylesheet" href="http://maxcdn.bootstrapcdn.com/bootstrap/3.2.0/css/bootstrap.min.css">
</head>
<body ng-controller="addController">
<div class="col-sm-10">
<fieldset ng-repeat="item in tableNames track by $index">
<span> TextBox1:<input type="text" ng-model="item.item1" />
TextBox2:<input type="text" ng-model="item.item2" /></span>
</fieldset>
<button class="btn btn-default" ng-click="addNewColumn()">Add Colname</button>
</div>
<pre>{{tableNames|json}}</pre>
</body>
</html>
So when I enter text in the textbox1 and textbox2 it shows array of below format:
[{
"item1":"textbox1value",
"item2":"textbox2value"
}]
and also when i click addColname button and generate another textbox, values are pushed in different property as follows,it generates:
[{
"item1":"textbox1value",
"item2":"textbox2value"
},
{
"item1":"textbox1value",
"item2":"textbox2value"
}
]
but what actually i need is of structure,
[{
"textbox1value":"textbox2value",
"textbox1value":"textbox2value",
.....
}]
note(:"textboxvalue" are values entered inside textboxes.
somebody help me to get desired output. thanks in advance

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: ''
};
});

I am trying to have the web page as easy to use with the keyboard as with the mouse and need to be able to respond when a control receives and loses the focus. I've built a small plunk to illustrate this. I've used the event names from jquery as the documentation seemed to say that was the appropriate thing to do.
Tabbing through the screen to each button should show text saying which button has focus.
Here's the html
<!DOCTYPE html>
<html ng-app="app">
<head>
<title>Demo</title>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"> </script>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.0/angular.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.0/angular-route.js"></script>
<script type="text/javascript" src="script.js"></script>
</head>
<body data-ng-controller="bbbb">
<input id="b1" type="button" value="button1">
<input id="b2" type="button" value="button2">
<input id="b3" type="button" value="button3">
<h2 ng-show="showb1">Button1 has focus</h2>
<h2 ng-show="showb2">Button2 has focus</h2>
<h2 ng-show="showb3">Button3 has focus</h2>
</body>
</html>
and the js
var app = angular.module('app', []);
var controllerId = 'bbbb';
app.controller('bbbb', ['$scope', function ($scope) {
$scope.showb1 = false;
$scope.showb2 = false;
$scope.showb3 = false;
var b1 = angular.element('#b1');
b1.on('focusin', function (event) {
$scope.showb1 = true;
});
b1.on('focusout', function (event) {
$scope.showb1 = false;
});
var b2 = angular.element('#b2');
b2.on('focusin', function (event) {
$scope.showb2 = true;
});
b2.on('focusout', function (event) {
$scope.showb2 = false;
});
var b3 = angular.element('#b3');
b3.on('focusin', function (event) {
$scope.showb3 = true;
});
b3.on('focusout', function (event) {
$scope.showb3 = false;
});
}
]);
Help greatly appreciated
