I've created a basic angular form and can't determine why it's not submitting.
http://contact-info.checkoutbiblebowl.com/
The form validation is valid and it still won't submit. I feel like I've overlooked something silly, but have looked at this over the last few days and can't figure out what it is. Any suggestions?
<form method='post' action='' name='form' novalidate ng-controller="myController">
<div class="row form">
<div class="form-inline">
<div class="form-row">
<label class="form-label" style='margin-top: 20px'>Name</label>
<div class="form-item">
<div style="float: left">
First<br/>
<input type="text" ng-model="firstName" name="firstName" class="small" style="width: 200px" maxlength="32" required>
<div ng-cloak ng-show="form.firstName.$error.required" class="required">First name is required</div>
</div>
<div style="float: left; margin-left: 1em">
Last<br/>
<input type="text" ng-model="lastName" name="lastName" class="small" style="width: 200px" maxlength="32" required>
<div ng-cloak ng-show="form.lastName.$error.required" class="required">Last name is required</div>
</div>
<div style="clear:both"></div>
</div>
</div>
<div class="button-row">
<button ng-disabled="!form.$valid" type="submit" class="btn" ng-click="debug()">Submit</button>
</div>
</div>
</div>
</form>
My Controller:
<script type="text/javascript">
angular.module('contact', []).
controller('myController', function ($scope) {
$scope.debug = function () {
console.log($scope.form);
}
});
</script>
I think you just need to specify the action explicitly, not with an empty string otherwise angular will prevent the submission.

I Want to validate when user clicks the button, and mark in red the field that have erros, but I'm pretty new with angular so I not sure how I do that, if some one could give me example I'll be able to finish my application. Thank you everyone.
As mentioned in Gonzalo's answer, "you should be add attribute name to the inputs that you want validate".
After it, you can use ngMessages to validate your inputs.
Here's a snippet working:
var app = angular.module('app', ['ngMessages']);
app.controller('mainCtrl', function ($scope) {
// Any JS code.
});

I would recommend you to check this tutorial also.
PS: As you may have noticed I commented all the "ng-include" (which contains the file that contains all the messages to show when input is invalid) that I put, because I don't know even if is possible to add a new "file" here in snippet, but I'm posting here almost the complete code and you can check the complete here.
error-messages.html:
<p ng-message="required">This field is required</p>
<p ng-message="minlength">This field is too short</p>
<p ng-message="maxlength">This field is too long</p>
<p ng-message="required">This field is required</p>
<p ng-message="email">This needs to be a valid email</p>
I hope it helps!!
Firstly, you should be add attribute name to the inputs that you want validate.
Then In the controller, more specifically in the $scope object, you have available a key with the name of your form, and inside this, keys associated to each input that you added a name attrubute.
Example based in your html:
angular
.module('exampleApp')
.controller('ExampleController', Controller);
Controller.$inject = ['$scope'];
function Controller($scope){
var vm = this;
var theForm = $scope.cadastroEmpresa;
console.log(theForm);
vm.handleValidation = function(){
var theForm = $scope.cadastroEmpresa;
console.log($scope);
console.log($scope.cadastroEmpresa);
}
}
Working

Form validation works when automatically when you submit the form. So you should add a submit type button anywhere inside the form like:
<button type="submit" class="btn btn-primary">Submit data</button>
And if you now require proper validation message and if you are using Bootstrap library, you can check out this library to provide validation messages in Angular with Bootstrap.
You just need to create a CSS for that, angular already adds the required classes for validation.
this class is added automatically to required fields, you just need to give it your style, for example:
.ng-submitted .ng-invalid {
color: #f00;
border: 1px solid #f00;
}

I am working on AngularJS with ui-grid. In the grid when i edit a row I am opening a modal window like this
$scope.editRow = function(row){
var modalInstance = $modal.open({
templateUrl : contextPath+ '/row/edit',
controller : 'EditController',
size : 'lg',
scope: $scope,
resolve : {
result : function() {
return row;
}
}
});
modalInstance.result.then(function() {
.......
});
}
and the model window gets open with the row details after calling Editcontroller default function. Until this point it is working fine.
Now i am trying to do the validation on the opened modal window using AngularUI and the validation is not working. Below is my UI page where the validation is not working
<div class="modal-content">
<div class="modal-header">
<h4 class="modal-title"></h4>
<h3 align="center">Edit Row Details</h3>
</div>
<div class="modal-body">
<form class="form-horizontal" name="myform" ng-submit="submitForm(myform.$valid)" novalidate>
<!-- Content Start -->
<div class="container">
<div class="row">
<div class="form-group required"
ng-class="{ 'has-error' : myform.name.$invalid && !myform.name.$pristine }">
<label for="name" class="control-label"> Name
</label>
<div>
<input type="text" name="myform.name" class="form-control input-sm"
ng-model="myform.name" placeholder="Name"
required />
<p ng-show="myform.name.$invalid && !myform.name.$pristine" class="help-block"> Name is required.</p>
</div>
</div>
</div>
<div class="row">
<div class="form-group">
<div>
<button type="submit" ng-model="myform.save" ng-disabled="myform.$invalid"
class="btn btn-primary" ng-click="edit(myform)">EDIT</button>
</div>
</div>
</div>
</div>
<!-- Content End -->
</form>
</div>
Somebody please help me how to do the validation. one more thing if i open the modal window normally the validation is working but i have the issue when i edit the row. I think this is a scope issue and the child scope is not getting bind. Your help is very much appreciable.
You don't need to include the form name in the name of the input, it's within a form so the input is bound to that form already. I'd also recommend binding your ng-model to another object on your scope (below I've used model) rather then the form itself.
You would write it like this.
<div class="row">
<div class="form-group required"
ng-class="{ 'has-error' : myform.name.$invalid && !myform.name.$pristine }">
<label for="name" class="control-label"> Name </label>
<div>
<input type="text" name="name" class="form-control input-sm"
ng-model="model.name" placeholder="Name"
required />
<p ng-show="myform.name.$invalid && !myform.name.$pristine" class="help-block"> Name is required.</p>
</div>
</div>
</div>
Also I'd change the ng-submit to the following
<form class="form-horizontal" name="myform" ng-submit="myform.$valid && submitForm()" novalidate>
Finally, I am able to find the solution
in EditController add below code
$scope.form={};
and your form should have form.myform like this
<div class="modal-content">
<div class="modal-header">
<h4 class="modal-title"></h4>
<h3 align="center">Edit Row Details</h3>
</div>
<div class="modal-body">
<form class="form-horizontal" name="form.myform"
ng-submit="submitForm(form.myform.$valid)" novalidate>
<!-- Content Start -->
<div class="container">
<div class="row">
<div class="form-group required"
ng-class="{ 'has-error' : form.myform.name.$invalid && !form.myform.name.$pristine }">
<label for="name" class="control-label"> Name </label>
<div>
<input type="text" name="myform.name"
class="form-control input-sm" ng-model="myform.name"
placeholder="Name" required />
<p ng-show="form.myform.name.$invalid && !form.myform.name.$pristine"
class="help-block">Name is required.</p>
</div>
</div>
</div>
<div class="row">
<div class="form-group">
<div>
<button type="submit" ng-model="myform.save" ng-disabled="form.myform.$invalid" class="btn btn-primary"
ng-click="edit(myform)">EDIT</button>
</div>
</div>
</div>
</div>
<!-- Content End -->
</form>
</div>
I am posting this becoz it may be helpful someone..
<form name="LPform">
<div class="form-row clearfix">
<label class="lbl-fld" style="margin-left: 12%;">Email ID</label>
<input class="mob-adj-inpbx" type="email" name="uemail" ng-model="useremail" placeholder=" me#example.com" ng-required="true"/>
<div ng-show="LPform.uemail.$valid">Enter a valid email.</div>
</div>
</form>
Here, I'm adding validations to 'email' and trying to display error message only when the user enters invalid email. However this is not working.
I suppose you want to show the error message if the input is invalid so
ng-show="!LPform.uemail.$valid"
Maybe you forgot to bind it to a scope variable? cause it seems to work fine.
function Ctrl($scope) {
$scope.useremail = '';
}
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.9/angular.min.js"></script>
<div ng-app>
<div ng-controller="Ctrl">
<form name="LPform">
<div class="form-row clearfix">
<label class="lbl-fld">Email ID</label>
<input class="mob-adj-inpbx" type="email" name="uemail" ng-model="useremail" placeholder=" me#example.com" ng-required="true" />
<div style="font-size: 11px; color: red; margin: 5px 65px;"
ng-show="!LPform.uemail.$valid">Please enter a valid email.</div>
</div>
</form>

I am trying to modify the Jhipster template by doing the following:
If the user is not authenticated , the authentication form is showing (instead of showing a link to the authentication page as it is set by default). I m showing it in the main.html view
<div class="row">
<div class="col-md-4">
<span class="hipster img-responsive img-rounded"></span>
</div>
<div class="col-md-8">
<h1 translate="main.title">Welcome, Java Hipster!</h1>
<p class="lead" translate="main.subtitle">This is your homepage</p>
<div ng-switch="authenticated">
<div class="alert alert-success" ng-switch-when="true"
translate="main.logged.message" translate-values="{username: '{{account.login}}'}">
You are logged in as user "Admin".
</div>
<div ng-switch-when="false">
<div class="row">
<div class="col-md-4">
<h1 translate="login.title">Authentication</h1>
<div class="alert alert-danger" ng-show="authenticationError" translate="login.messages.error.authentication">
<strong>Authentication failed!</strong> Please check your credentials and try again.
</div>
<form class="form" role="form" ng-submit="login()">
<div class="form-group">
<label for="username" translate="global.form.username">Login</label>
<input type="text" class="form-control" id="username" placeholder="{{'global.form.username.placeholder' | translate}}" ng-model="username">
</div>
<div class="form-group">
<label for="password" translate="login.form.password">Password</label>
<input type="password" class="form-control" id="password" placeholder="{{'login.form.password.placeholder' | translate}}"
ng-model="password">
</div>
<div class="form-group">
<label for="rememberMe">
{{"login.form.rememberme" | translate}}
<input type="checkbox" class="checkbox inline_class" id="rememberMe"
ng-model="rememberMe" checked>
</label>
</div>
<button type="submit" class="btn btn-primary" translate="login.form.button">Authenticate</button>
</form>
<p></p>
<div class="alert alert-warning" translate="global.messages.info.register">
You don't have an account yet? Register a new account
</div>
</div>
</div>
</div>
</div>
</div>
</div>
and modified apps.js :
.otherwise({
templateUrl: 'views/main.html',
controller: 'LoginController',
access: {
authorizedRoles: [USER_ROLES.all]
}
});
It works if I m not using the ng-switch-when="false" statement.
If I m using this statement, the value of $scope.password and $scope.login are "undefined" in the LoginController.
Of course this statement is mandatory if I want to show the authentication form only if the user is not authenticated.
I can't understand why.
If you can help me on this, it would be great.
Thanks.
It's a common gotcha with ng-switch and other directives that create sub-scopes. This should work:
<div class="row">
<div class="col-md-4">
<span class="hipster img-responsive img-rounded"></span>
</div>
<div class="col-md-8">
<h1 translate="main.title">Welcome, Java Hipster!</h1>
<p class="lead" translate="main.subtitle">This is your homepage</p>
<div ng-switch="authenticated">
<div class="alert alert-success" ng-switch-when="true"
translate="main.logged.message" translate-values="{username: '{{account.login}}'}">
You are logged in as user "Admin".
</div>
<div ng-switch-when="false">
<div class="row">
<div class="col-md-4">
<h1 translate="login.title">Authentication</h1>
<div class="alert alert-danger" ng-show="authenticationError" translate="login.messages.error.authentication">
<strong>Authentication failed!</strong> Please check your credentials and try again.
</div>
<form class="form" role="form" ng-submit="login()">
<div class="form-group">
<label for="username" translate="global.form.username">Login</label>
<input type="text" class="form-control" id="username" placeholder="{{'global.form.username.placeholder' | translate}}" ng-model="$parent.username">
</div>
<div class="form-group">
<label for="password" translate="login.form.password">Password</label>
<input type="password" class="form-control" id="password" placeholder="{{'login.form.password.placeholder' | translate}}"
ng-model="$parent.password">
</div>
<div class="form-group">
<label for="rememberMe">
{{"login.form.rememberme" | translate}}
<input type="checkbox" class="checkbox inline_class" id="rememberMe"
ng-model="$parent.rememberMe" checked>
</label>
</div>
<button type="submit" class="btn btn-primary" translate="login.form.button">Authenticate</button>
</form>
<p></p>
<div class="alert alert-warning" translate="global.messages.info.register">
You don't have an account yet? Register a new account
</div>
</div>
</div>
</div>
</div>
</div>
Instead of $parent you may bind values to an object, but then you will need to modify Jhipster's LoginController accordingly (and also make sure to update login.html or create a variant of the controller for the main screen only)
I have the following code:
<div id="messageArea">
<div ng-messages="text1.$error">
<div ng-message="required">
Text1 is required ...
</div>
</div>
<div ng-messages="text2.$error">
<div ng-message="required">
Text2 is required ...
</div>
</div>
<div ng-messages="text3.$error">
<div ng-message="required">
Text3 is required ...
</div>
</div>
</div>
<div>Text1<input id="text1" ng-model="text1" name="text1" ng-required="true"></div>
<div>Text2<input id="text2" ng-model="text2" name="text2" ng-required="true"></div>
<div>Text3<input id="text3" ng-model="text3" name="text3" ng-required="true"></div>
I wanted to show one error message at a time. When the first error is solved then the next error message will show. Anyone has any idea how I can do this? Thanks.
Nice solution is use CSS and ng-class
var app = angular.module('app', ['ngMessages']);
.error-wrapper {
color: red;
}
.error-wrapper > .view {
display: block;
}
.error-wrapper > .view ~ .view{
display: none;
}

It's show only the first error message with class .view, at the plunker http://plnkr.co/edit/kBSpRJLs6QA2D0jctKXB?p=preview
If you wrap the inputs in a form tag with an ID you can use ng-messages on the form to pick up errors from all the inputs. You can see this here: http://jsbin.com/tikufuvawe/2/edit.
<form name="userDetails">
<input name="userName" type="number" ng-model="number" required ng-maxlength="2" />
<textarea name="text" type="text" ng-model="text" required></textarea>
<div ng-messages="userDetails.$error">
<div ng-message="required">This is required</div>
</div>
</form>
EDIT:
I have updated my example http://jsbin.com/zadojamifo/3/edit using ng-show to hide other errors such that only one will show at a time. Its not a great solution but works for the situation described.
<div ng-messages="userDetails.number.$error">
<div ng-message="required">number is required</div>
</div>
<div ng-messages="userDetails.text.$error" ng-show="!userDetails.number.$error.required">
<div ng-message="required">text is required</div>
</div>
<div ng-messages="userDetails.other.$error" ng-show="!userDetails.number.$error.required && !userDetails.text.$error.required">
<div ng-message="required">other is required</div>
</div>
As you can see the ng-show will get bigger and bigger in size if more validation types are added and if more controls are added that require validation.
Maybe is too late but this is my solution, use ng-messages-multiple to show one or more message, angular respect the order of validation messages:
<form name="loginForm" ng-submit="login()">
<label>Email</label>
<input required name="email" type="email" ng-model="email">
<div ng-messages="loginForm.email.$error" ng-show="loginForm.email.$dirty && loginForm.email.$invalid" ng-messages-multiple>
<div ng-message="required">El email es requerido!</div>
<div ng-message="email">El email debe cumplir con el formato: email#dominio.com!</div>
</div>
<label>Contraseña</label>
<input required name="password" type="password" ng-model="password" ng-pattern="passwordPattern" md-maxlength="12">
<div ng-messages="loginForm.password.$error" ng-show="loginForm.password.$dirty && loginForm.password.$invalid">
<div ng-message="required">La contraseña es requerida!</div>
<div ng-message="pattern">Se requieren de 6 a 12 caracteres, por lo menus un dígito, una letra mayuscula y una minúscula</div>
</div>
<div layout="row" layout-align="center center">
<button ng-disabled="loginForm.$invalid>Login</button>
</div>
</form>
You can do something like this
<div id="messageArea">
<div ng-messages="number.$error">
<div ng-message="required">
Number is required ...
</div>
</div>
<div ng-messages="text.$error" ng-if="!number.$error">
<div ng-message="required">
Text is required ...
</div>
</div>
In this case you show the second block of messages only if the first one does not exists (and it's hidden if number.$errors exists)
This sample (http://www.yearofmoo.com/2014/05/how-to-use-ngmessages-in-angularjs.html) uses a follow solution:
<div ng-messages="my_form.first_name.$error"
ng-if="interacted(my_form.first_name)">
$scope.submitted = false;
$scope.submit = function() {
$scope.submitted = true;
};
$scope.interacted = function(field) {
return $scope.submitted || field.$dirty;
};
If you don't want to show on page load but either on page submit or on change of value then use
<form name="frmSome">
<div ng-messages="userDetails.$error"
ng-if='frmSome.userName.$dirty || frmSome.$submitted'>
<span ng-message="required">Name is Required</span>
<span ng-message="maxlength">Max. 100</span>
</div>
<input name="userName" type="text"
ng-model="model.name"
ng-required='true'
ng-maxlength="30" />
..............................
..............................
<input type='submit' value='Submit' />
</form>
If you touch the text box it will be "dirty"
if try to submit the page "Submitted"
It works on the name not the model
