I have a very simple form and a strange behaviour:
<form name='signup_form' novalidate ng-submit=signupForm()>
<div class="row">
<div class="large12 columns">
<label>Email</label>
<input type="email" placeholder="Email"
name="email"
ng-model="signup.email"
required />
<div class="error" ng-show="signup_form.email.$dirty &&
signup_form.email.$invalid">
<small class="error" ng-show="signup_form.email.$error.required">
Email address is required
</small>
<small class="error" ng-show="signup_form.email.$error.email">
This is not a valid email
</small>
</div>
</div>
</div>
<button type='submit' class="button radius">Submit</button>
</form>
Typing email...:
still typing - making it valid...:
Label has disagreed it is showing back when I click anywhere on the page.
Angular.js : https://ajax.googleapis.com/ajax/libs/angularjs/1.4.5/angular.js
I don't use any custom css.

I am doing one register page using angularjs.
Follows my html code:
<form name="frominline" action="post" class="clearfix form-hidden" id="Register-form">
<div class="col-md-12">
<div class="input-group blmd-form">
<div class="blmd-line">
<input type="text" name="userid" autocomplete="off" id="username" class="form-control" required autofocus="" ng-model="user.name" ng-minlength="3" ng-maxlength="12" ng-model-options="{ allowInvalid: true }">
<label class="blmd-label">User Id</label>
</div>
<p class="login-error" ng-show="frominline.userid.$dirty && frominline.userid.$error.required">
<span style="color : red">required</span>
</p>
<p ng-show="frominline.userid.$error.minlength" class="help-block" style="color:red;">Username is too short.</p>
<p ng-show="frominline.userid.$error.maxlength" class="help-block" style="color:red;">Username is too long.</p>
</div>
<div class="input-group blmd-form">
<div class="blmd-line">
<input type="email" name="email" autocomplete="off" id="email" class="form-control" required autofocus="" ng-model="user.email">
<label class="blmd-label">Email</label>
</div>
<span class="login-error" ng-show="frominline.email.$error.required && frominline.email.$dirty" style="color:red;" ng-model-options="{ allowInvalid: true }">required</span>
<span class="login-error" ng-show="!frominline.email.$error.required && frominline.email.$error.email && frominline.email.$dirty" style="color:red;">invalid email</span>
</div>
<button type="reset" ng-click="resetform(frominline)">reset</button>
</form>
My js code:
app.controller('loginCtrl'['$scope',function('$scope'){
var user = this;
$scope.resetform(form){
user.name='';
user.email='';
$scope.frominline.$dirty = false;
$scope.frominline.$pristine = true;
$scope.frominline.$submitted = false;
}]);
Now, in first image, those are the validation errors.
Now, I hit the reset button and the validation errors are gone but in the second image I got required field.
Can you please help me removing or reseting the whole form on a button click?
I tried with many options like $setPristine() or $setValidity() but i can't fix this issue "required" error message.
Follows the image of the form with only required error message after clicking reset button:
The form is probably cleared, but those input fields are not. When you are display the error for a particular field (e.g. ng-show="frominline.userid.$error.minlength") include the state of the form as well (e.g. ng-show="frominline.$submitted && frominline.userid.$error.minlength").
Angular seems to not be raising minLength or maxLength error in the below code... the required error (as well as the email error) is working however. I know ng-minlength and ng-maxlength is working because the input box is changing its CSS. The text inside the <span> is not working for the min or max errors.
See the password input below:
<section class="row" data-ng-controller="AuthenticationController">
<h3 class="col-md-12 text-center">Sign Up</h3>
<div class="col-xs-offset-2 col-xs-8 col-md-offset-5 col-md-2">
<form name="userForm" data-ng-submit="userForm.$valid && signup()" class="signin form-validate" novalidate autocomplete="off">
<fieldset>
<div class="form-group">
<span ng-show="userForm.email.$dirty && userForm.email.$error.required" class="text-danger">This field is required</span>
<span ng-show="userForm.email.$dirty && userForm.email.$error.email" class="text-danger">This field must be a valid email address</span>
</div>
<div class="form-group">
<label for="username" class="control-label">Username</label>
<input type="text" id="username" name="username" class="form-control" data-ng-model="credentials.username" placeholder="Username">
</div>
<div class="form-group">
<label for="password" class="control-label">Password</label>
<input type="password" id="password" name="password" class="form-control" required data-ng-model="credentials.password" ng-minlength="8" ng-maxlength="24" placeholder="Password">
<span ng-show="userForm.password.$dirty && userForm.password.$error.required" class="text-danger">This field is required</span>
<span ng-show="userForm.password.$dirty && userForm.password.$error.minLength" class="text-danger">Please use a password of at least 8 characters</span>
<span ng-show="userForm.password.$dirty && userForm.password.$error.maxLength" class="text-danger">The charactar limit for passwords is 24</span>
</div>
<div class="text-center form-group mt">
<button type="submit" class="btn btn-large btn-primary">Sign up</button> or
Sign in
</div>
<div data-ng-show="error" class="text-center text-danger">
<strong data-ng-bind="error"></strong>
</div>
</fieldset>
</form>
</div>
any thoughts on what's gone wrong here?
It was just a syntax error: userForm.password.$error.minLength should have been userForm.password.$error.minlength (capitalization).
You should change && to && inside ng-show expression, you must have getting an error in console.
The updated ng-show version will look something like below.
ng-show="userForm.password.$dirty && userForm.password.$error.required"
The other more convenient way is to use ng-messages directive, to show and hide validation messages based on form & its field validity
I tried and searched a lot, but no solution. The form validation in my angular app still not working.
I tried for example:
<form data-ng-controller="ValidationController" name="validationForm" novalidate="novalidate">
<div class="form-group">
<label for="username">Mail</label>
<input name="username"
type="email"
data-ng-model="formData.username"
required="required">
<span ng-show="form.username.$invalid">Invalid mail address</span>
</div>
<button type="submit" class="btn btn-primary" data-ng-disabled="formData.$invalid">Submit</button>
<pre>
<tt>formData = {{formData}}</tt><br/>
<tt>formData.$valid = {{formData.$valid}}</tt><br/>
<tt>formData.username.$valid = {{formData.username.$valid}}</tt><br/>
<tt>formData.username.$error = {{formData.username.$error}}</tt><br/>
<hr>
</pre>
</form>
Another one I tried:
<div class="row">
<div class="large-12 columns">
<label>Your email</label> <input type="email" placeholder="Email"
name="email" ng-model="signup.email" ng-minlength=3 ng-maxlength=20
required />
<div class="error-container"
ng-show="signup_form.email.$dirty && signup_form.email.$invalid">
<small class="error" ng-show="signup_form.email.$error.required">
Your email is required. </small> <small class="error"
ng-show="signup_form.email.$error.minlength"> Your email is required
to be at least 3 characters </small> <small class="error"
ng-show="signup_form.email.$error.email"> That is not a valid email.
Please input a valid email. </small> <small class="error"
ng-show="signup_form.email.$error.maxlength"> Your email cannot be
longer than 20 characters </small>
</div>
</div>
</div>
But the validation does not work. If I have to enable the validation? But for this I also didn't find anything. It seems, that validation is still enabled in Angular. But why it does not work in my app? All other things works fine.

Try this:
<form data-ng-controller="ValidationController" name="validationForm" novalidate="novalidate">
<div class="form-group">
<label for="username">Mail</label>
<input name="username"
type="email"
data-ng-model="username"
required>
<span ng-show="validationForm.username.$invalid && validationForm.username.$dirty">Invalid mail address</span>
</div>
<button type="submit" class="btn btn-primary" data-ng-disabled="formData.$invalid">Submit</button>
<pre>
<tt>formData = {{validationForm}}</tt><br/>
<tt>formData.$valid = {{validationForm.$valid}}</tt><br/>
<tt>formData.username.$valid = {{validationForm.username.$valid}}</tt><br/>
<tt>formData.username.$error = {{validationForm.username.$error}}</tt><br/>
<hr>
</pre>
</form>
Actually your form is available by its name.
Check this plnkr.
You have some errors there.
First:
ng-show="form.username.$invalid"
You are referencing a variable form that does not exist in your scope. You should reference validationForm:
ng-show="validationForm.username.$invalid"
Second:
data-ng-disabled="formData.$invalid"
You are referencing the model of the input, instead of it's form object, that is, again, validationForm:
data-ng-disabled="validationForm.$invalid"
That should do.
Is there an automated way in Angular to display the error messages for invalid form. For Example, I have the below. It indeed works well in that it doesn't allow the user to submit but it doesn't give the user any automatic feedback to tell them that elements are required. Isn't there an automatic way to get it to print a field is required message by the field if the form is invalid on submit?
<div class="form-center">
<form name="loginform" class="forms" ng-controller="controllers.LoginController">
<fieldset> <legend><h3>Account Login</h3></legend>
<div class="advanced-search-item">
<label>Username:</label><br /> <input type="text" ng-model="username" name="username" placeholder="username" required><span class="error" ng-show="submitted && loginform.username.$error.required">Required!</span>
</div>
<div class="advanced-search-item">
<label>Password:</label><br />
<input type="password" name="password" ng-model="password" placeholder="password" required><span class="error" ng-show="submitted && loginform.username.$error.required">Required!</span>
</div>
<div class="advanced-search-item">
Login
</div>
</fieldset>
</form>
</div>
You will have to add some spans to show errors beside input fields like below
<span class="error" ng-show="submitted && loginform.username.$error.required">Required!</span>
<span class="error" ng-show="submitted && loginform.password.$error.required">Required!</span>
Hopefully you can keep this text in red color, below is the CSS
.error {
padding-left:10px;
color: #F00;
}
when form is submitted and if there are errors it will show above spans
Hope this helps

There are 2 mistakes in your code.
First one, you used - in your fields id (login-Name and login-Password). Replace them by _ (login_Name and login_Password). Angularjs see them as the substract operator and doesn't return an object to evaluate in the ng-show directives.
For the username (the email address), your error will never be displayed since the $error.required is set to false as soon as the field is not empty and $dirty is set to false if the field is empty. Your 2 conditions cannot be true at the same time.
For the password, you have the same problem for the required field, but your 2 other validations will work if you change your id.
