Angularjs 1.2 Form validation


Angularjs 1.2 Form validation

Hope that helps rather than deactivating the submit button, you can allow user to submit. and if there are any errors, show those errors, and suspend the submit process
why is that better, if button is disabled, and no error message are displayed, user wont be able to know the reason why the button is disabled.
code :

With these it helps If the id field is not a form field, then you can add that to your form but add it as a non-mapped field (i.e. it doesn't relate to a property on the entity):
code :
$builder->add('id', 'hidden', array('mapped' => false));

seems to work fine Refer to my another answer: AngularJS v1.3.x Email Validation Issue
Try to use ng-pattern in your email input.
code :
<input type="email" name="input" ng-model="text" ng-pattern="/^[_a-z0-9]+(\.[_a-z0-9]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,4})$/" required>

it should still fix some issue I've made form validation using angularjs. But I am facing a problem Which is error message shown at the page load. But this message will show after getting error. Just I want to remainder that I have set validation summary using directive. What can I do? , You can add new Variable in scope to check if form is submitted.
code :
$scope.isFormSubmit = false
if($scope.form.$valid)
{
      //Submit your form
      $scope.isFormSubmit = false
}
else
{
     $scope.isFormSubmit = true
}
<div validation-message ng-show="customerForm.UserName.$error.required && isFormSubmit" class="error">
 Username is required
</div>

will be helpful for those in need I think the main benefit is the ability to testing and ease of use. Angular approaches form validation declaratively whereas more complex JQuery validation is done via JavaScript. Angular validation falls in line with the way HTML5 elements should be validated and it believes all validation constraints should be declared in the markup rather than in code (which I agree).
The biggest problem (in my opinion) with validation in angular is that while it is good pratice to decalare your validation rules on the element that displays the data I don't believe it is good practice to have to also define your validation messages in markup at the same time.
code :
<form name="signupFrm" novalidate="novalidate">  
  <div classs="form-row">
    <label>Username:</label>
    <input name="username" 
    ng-model="model.username"
    ng-minlength="3"
    ng-maxlength="10"
    required/>
    <div class="errors" 
    ng-show="signupFrm.username.$dirty && signupFrm.username.$invalid">
      <small class="error" ng-show="signupFrm.username.$error.required">Please input a username</small>
      <small class="error" ng-show="signupFrm.username.$error.minlength">Please enter a min length of 3</small>
      <small class="error" ng-show="signupFrm.username.$error.maxlength">Please enter a max length of 10</small>
  </div>
</div>

it helps some times There's no built-in functionality, but it requires little effort.
ng-messages does not depend on anything specific. It just needs an object whose keys can be referenced by ng-message. The simplest solution would be to hook into the submit event (which you probably do anyway) and run additional validation.
code :
<form ng-submit="post()" name="myForm">
  <input type="checkbox" name="one" ng-model="one" />
  <input type="checkbox" name="two" ng-model="two" />
  <input type="submit" />
  <div ng-messages="formErrors">
    <p ng-message="tooMany">Please, check one checkbox only</p>
    <p ng-message="required">Please, check a checkbox</p>
  </div>
</form>
$scope.post = function() {
  ...
  var hasErrors = false;
  $scope.formErrors = {
  };

  if ($scope.one && $scope.two) {
    $scope.formErrors.tooMany = hasErrors = true;
  }

  if (!$scope.one && !$scope.two) {
    $scope.formErrors.required hasErrors = true;
  }

  if (hasErrors) {
     return;
  }
}
