validate form on button in angularjs - angularjs

Question

I have to validate a form only after click on button. Now it is working on blur and focus. How can I disable focus and blur validation and validate them on button click. fiddle
<form ng-app="form-example" class="row form-horizontal" novalidate>
<div class="control-group">
<label class="control-label" for="inputEmail">Email</label>
<div class="controls">
<input type="email" id="inputEmail" placeholder="Email" ng-model="email" required>
<div class="input-help">
<h4>Invalid Email</h4>
</div>
</div>
</div>
<div class="control-group">
<label class="control-label" for="inputPassword">Password</label>
<div class="controls">
<input ng-model="password" class="immediate-help" required type="password" id="inputPassword" placeholder="Password">
<div class="input-help">
<ul>
<li>required</strong></li>
</ul>
</div>
</div>
</div>
<div class="control-group">
<div class="controls">
<button class="btn">Create Account</button>
</div>
</div>
</form>

Answer 1

You could have dummy class on your form level that will tell the form has been submitted or not like ng-class="{submitted: submitted}", and on click of button we will use ng-click="submitted=true" so that after clicking on button form will have submitted class on it. Then we will apply our CSS rule for ng-invalid & ng-dirty to also consider an .submitted class by using concept of deep nesting of classes.
/* Show red border when stuff has been typed in, but its invalid */
.submitted .ng-dirty.ng-invalid {
border-color:#ec3f41;
}
Other CSS rules should be taken care of this thing like I shown above.

the problem is that you just added the validation and you're showing the message on ng-invalid ( with css). here is an example of working code to do what you want.
<div class="form-group col-xs-12 required" ng-class="{ 'has-error' : creditCardDetailsForm.security_code.$invalid && submitted}">
<label class="col-lg-28 col-l-5 col-md-5 text-left font-l-20 primary control-label">Security code (CVC) </label>
<div class="col-lg-3 col-md-4 text-left">
<input class="form-control" name="security_code" data-stripe="cvc" ng-model="payment_details.security_code" type="number" minLength="3" required>
<p ng-show="creditCardDetailsForm.security_code.$invalid && submitted" class="help-block">Security code is required.</p>
<p ng-show="creditCardDetailsForm.security_code.minLength.$invalid && submitted" class="help-block">Invalid CVC.</p>
</div>
</div>
see, here I check if the form is invalid and the submitted has been clicked...
in my controller:
$scope.purchasePackage = function (status, response) {
$scope.submitted = true;
if ($scope.creditCardForm.creditCardDetailsForm.$valid) {
//do something
}
};
since you did your hide and show with CSS you can just add the class on click to the form and then do .submitted .ng-invalid so it only shows up after you have submitted.
