Firstly if have only one form on page, like:
<form class="form-horizontal" name="formCreateCtb">
...
Then i can easily access it in my controller in following way:
$scope.formCreateCtb.$setPristine(); // reset form validation
But as soon as i added second form on page, like:
<form class="form-horizontal" name="formCreateCtb">
...
<form class="form-horizontal" name="formCreateCtbs">
...
Then i can't access second form in scope like previosly:
$scope.formCreateCtb.$setPristine(); // still work OK
$scope.formCreateCtbs.$setPristine(); // Exception: formCreateCtbs is underfined
Why this behavior, and how to access form in scope, when i have multiple forms on page.
Thanks!
EDIT:
It seems the issue is that in project i have more complex markup, the second form
live in bootstrap tab, that is not visible at the moment of forms shown.
When i added second form out of modal, it works fine. The workaround is wrap entire tabs in one form element.
Use the ng-form directive

I am creating a to-do list in angular js. I am trying to access the form in the controller. However, when I click the add new button, it doesn't add to the list.
There is also no error displaying which shows to me that the function probably isn't doing anything.
How do I get the add new button to add to the list.
Here is the index.html:

Here is app.js:
var app = angular.module('myApp', []);
app.controller('todoCtrl',['$scope' ,function ($scope) {
$scope.toDoList = [{todoText: "check", done: false}];
function todoAdd() {
var vm=this;
vm.toDoAdd=toDoAdd;
$scope.toDoAdd = function () {
$scope.toDoList.push({todoText: $scope.todoInput, done: false});
$scope.todoInput = "";
}
}
}])
I have made some changes to your application:
<body ng-app="myApp" ng-controller="todoCtrl">
<form ng-submit="toDoAdd()">
<input type="text" ng-model="todoInput" size="50" placeholder="Add New">
<input type="submit" value="Add New">
<br>
<div ng-repeat="x in toDoList">
<input type="checkbox" ng-model="x.done" /><span ng-bind="x.todoText">
</span>
</div>
<p>
<button type="button" ng-click="remove()">Remove marked</button></p>
</form>
</body>
var app = angular.module('myApp', []);
app.controller('todoCtrl',['$scope' ,function ($scope) {
$scope.toDoList = [{todoText: "check", done: false}];
$scope.toDoAdd = function () {
$scope.toDoList.push({todoText: $scope.todoInput, done: false});
$scope.todoInput = "";
}
}])
There are two ways of using controllers, one with $scope and other with controller as vm in this case for simplicity I am using $scope you can read more about the other notation in this guide

I am always getting the alert message from the else part which states form invalid
Form directive is bounded to scope, so you need to write it as $scope.sampleForm.$valid. Since your name is dynamic, you can use a bracket notation: $scope[form].$valid. But either way you need to inject $scope into your controller.
Here is a demo:

You are passing form as a string in ng-click method not a form Object.So u have to pass the form object without Single-cotts.
ng-click="sm.submitForm('sampleForm')" to ng-click="sm.submitForm(sampleForm)"
I am new to AngularJS. I am creating single page application in which a form consists of multiple steps. I have used buttons and input fields. Form is getting submitted. I want to fetch the form fields values but i don't know the ways to do it. I have added my code. I want to see what user is filling so i can store the values in database. How do i get my values in console log.? Please someone guide me how to do it.
// Code goes here
var app = angular.module("MyApp", ["ngAnimate"]);
app.controller('MyCtrl', function($scope, $timeout) {
$scope.submitForm = function(isValid) {
// check to make sure the form is completely valid
if (isValid) {
alert('our form is amazing');
console.log(myform);
}
};
$scope.sliderValue = null;
$scope.name = '';
$scope.data = {
singleSelect: null,
multipleSelect: [],
option1: 'option-1',
};
$scope.forceUnknownOption = function() {
$scope.data.singleSelect = 'nonsense';

My suggestion is to use data object for all of your ng-model inputs.
this is my JSFiddle example: JSFiddle
HTML:
<div ng-app>
<form ng-controller="FormController" name="myForm">
<div class="header padding-b--10">Form Area</div>
<div class="padding-b--10">
<input name="empId" placeholder="Employee ID" ng-model="data.empId"
style="padding:5px" required/>
<span ng-if="myForm.empId.$dirty && myForm.empId.$invalid" ng-bind="invalid" class="error"></span>
</div>
<div class="padding-b--10">
<input name="empEmail" type="email" placeholder="Email" ng-model="data.empEmail"
style="padding:5px" required/>
<span ng-if="myForm.empEmail.$dirty && myForm.empEmail.$invalid" ng-bind="invalid" class="error"></span>
</div>
<input type="button" value="Submit" ng-click="submit()" class="button" ng-disabled="myForm.$invalid">
<pre>{{data}}</pre>
<pre>myForm.empId.$valid = {{myForm.empId.$valid}}</pre>
<pre>myForm.empEmail.$valid = {{myForm.empEmail.$valid}}</pre>
</form>
</div>
JS:
function FormController($scope){
$scope.invalid = "Invalid";
$scope.submit = function(){
console.log($scope.data);
}
};
Is it possible in Angular to validate a single, isolated <input> in a similar way the forms are validated? I'm thinking about something like this:
<div class="form-group">
<input name="myInput" type="text" class="form-control" ng-model="bindTo" ng-maxlength="5">
<span class="error" ng-show="myInput.$error.maxlength">Too long!</span>
</div>
The example above doesn't work. Enclosing it in a <form> and replacing ng-show with ng-show="myForm.myInput.$error.maxlength" helps.
Is it possible to do this without using <form>?
You may use the ng-form angular directive (see docs here) to group anything, even outside a html form. Then, you can take advantage from angular FormController.
<div class="form-group" ng-form name="myForm">
<input name="myInput" type="text" class="form-control" ng-model="bindTo" ng-maxlength="5">
<span class="error" ng-show="myForm.myInput.$error.maxlength">Too long!</span>
</div>
Example
Building on Silvio Lucas' answer, if you are iterating in a loop and need to be able to interpolate form names and valid states:
<div
name="{{propertyName}}"
ng-form=""
class="property-edit-view"
ng-class="{
'has-error': {{propertyName}}.editBox.$invalid,
'has-success':
{{propertyName}}.editBox.$valid &&
{{propertyName}}.editBox.$dirty &&
propertyValue.length !== 0
}"
ng-switch="schema.type">
<input
name="editBox"
ng-switch-when="int"
type="number"
ng-model="propertyValue"
ng-pattern="/^[0-9]+$/"
class="form-control">
<input
name="editBox"
ng-switch-default=""
type="text"
ng-model="propertyValue"
class="form-control">
<span class="property-type" ng-bind="schema.type"></span>
</div>
