angular validation not working - angularjs

I am using angular validation on an html page, where I have defined a form along with validation on the form. However, when I run the page, all the validations I have used on the page is visible. Is there a way I can hide all the validations?
<form ng-controller="validateCtrl"
name="loginForm" novalidate>
<p>UserName:<br>
<input type="text" name="uName" ng-model="uName" required>
<span style="color:red" ng-show="loginForm.uName.$dirty && loginForm.uName.$invalid && loginForm.uName.$error.required">
Username is required
</span>
</p>
<p>Password:<br>
<input type="text" name="pwd" ng-model="pwd" required>
<span style="color:red" ng-show="loginForm.pwd.$dirty && loginForm.pwd.$invalid">
<span ng-show="loginForm.pwd.$error.required">Password is required.</span>
</span>
</p>
<p>
<input type="submit" ng-click="popupuser()"
ng-disabled="loginForm.$invalid ">
</p>
</form>
<script src="https://code.angularjs.org/1.2.3/angular.min.js"></script>

Your code for form is fine please see here http://jsbin.com/figuve/1/edit
Make sure that your validateCtrl exist otherwise validation will not work plase see here
http://jsbin.com/figuve/2/edit
or
remove ng-controller="validateCtrl" from your form if you don't need it.
please see here http://jsbin.com/figuve/3/edit

You can try use variable to check is form submited, like that
<span ng-show="(loginForm.uName.$dirty || isSubmitted) && loginForm.uName.$error.required">Username is required</span>

Resting Form and Clear Error Validations in register form on clicking a button

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").

ng-minlength Angular Form Validation

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

How to use element name in ng-show and form validation

I was looking at the W3school example of form validation for Angular JS, here is the code:
<form name="myForm">
<p>Name:
<input name="myName" ng-model="myName" required>
<span ng-show="myForm.myName.$touched && myForm.myName.$invalid">The name is required.</span>
</p>
<p>Adress:
<input name="myAddress" ng-model="myAddress" required>
<span ng-show="myForm.myAddress.$untouched">Please enter address.</span>
</p>
</form>
note the ng-show="myForm.myName.$touched", does Angular find the element's name attribute as default? What if the input has an id and I want to use that instead of name?
You can use this in below way..
<input name="myName" id="myNameId" ng-model="myName" required>
<span ng-show='angular.element($("#myNameId")).$touched && angular.element($("#myNameId")).$invalid'>The name is required.</span>
</p>

AngularJS and Bootstrap: Red border on invalid input field on submit

I've this basic form implemented using AngularJS and Bootstrap:
http://jsfiddle.net/dennismadsen/0stwd03k/
HTML
<div ng-controller="MyCtrl">
<form class="well" name="formTest" ng-submit="save()">
<div class="form-group">
<label for="name">Name*</label>
<input type="name" class="form-control" id="name" placeholder="Enter name" required />
</div>
<button type="submit" class="btn btn-default">Submit</button>
</form>
</div>
JavaScript
var myApp = angular.module('myApp', []);
function MyCtrl($scope) {
$scope.save = function () {
};
}
Result
The Name input field is required. When I click the submit button, I need the input field to have a red border if it's invalid. How can this be done?
Alternatively, if I unfocus the input field and it's still not valid, it would be great that the red corder is shown on that time, instead of waiting for the form submit.
Twitter Bootstrap has an has-error class, so I would use this in conjunction with ng-class for the form group, then a label with the label and label-danger classes for good measure:
<div class="form-group" ng-class="{'has-error': errors.Name }">
<label for="name">Name*</label>
<input type="name" class="form-control" id="name" placeholder="Enter name" required />
<span class="label label-danger" ng-if="errors.Name">{{errors.Name}}</span>
</div>
Then in your controller, have an errors object, and set the Name property of this to a string when the name is invalid.
The first thing you were missing was adding ng-model='name' to input field, then only will the form become invalid once you click submit, otherwise the form will always be valid since it considers that there is no field present.
Then I'd add the submitted class on the submit click button, then put the border css like .submitted would be the parent and .ng-invalid would be the child so we can put the style on .submitted .ng-invalid
HTML
<div ng-controller="MyCtrl">
<form class="well" name="formTest" ng-class="{'submitted': submitted}" ng-submit="save()" >
<div class="form-group">
<label for="name">Name*</label>
<input type="name" class="form-control" id="name" placeholder="Enter name" ng-model="name" required />
</div>{{submitted}}
<button type="submit" class="btn btn-default" ng-click="submitted= true;">Submit</button>
</form>
</div>
CSS
.submitted .ng-invalid{
border: 1px solid red;
}
Working Fiddle
Hope this could help you, Thanks.
Basically you need angular to take over validation, so add novalidate to form. Also add ng-class to input field to determine wether to add error css
<form name="myForm" novalidate ng-submit="test()">
<input type="text" name="user" ng-model="user" required ng-class="myForm.user.$invalid && myForm.user.$dirty ? 'error' : ''">
<span style="color:red" ng-show="myForm.user.$dirty && myForm.user.$invalid">
<span ng-show="myForm.user.$error.required">Username is required. </span>
</span>
<p>
<input type="submit"
ng-disabled="myForm.user.$dirty && myForm.user.$invalid ||
myForm.email.$dirty && myForm.email.$invalid">
</p>
</form>
Good luck..

AngularJS validation on submit only

I want to implement some simple form validation in my AngularJS app, but I don't want it to show any validation errors until after the user has clicked the form submit button. I don't want it to validate as I type or even on exiting the field.
Is there a way to do this? I'll need to write at least one custom validator directive so it will need to work with that.
I am finding form validation in AngularJS to be very difficult so far, it's hard to get it to work exactly as you want.
You could do something like this. Here's an example
<form name="form" ng-app>
<div class="control-group" ng-class="{true: 'error'}[submitted && form.email.$invalid]">
<label class="control-label" for="email">Your email address</label>
<div class="controls">
<input type="email" name="email" ng-model="email" required />
<span class="help-inline" ng-show="submitted && form.email.$error.required">Required</span>
<span class="help-inline" ng-show="submitted && form.email.$error.email">Invalid email</span>
</div>
</div>
<button type="submit" class="btn btn-primary btn-large" ng-click="submitted=true">Submit</button>
</form>
