In my form validation there is part of server validations. So I should get back from the server list with the names of the fields and a string with the error in each of them. My idea was to write a general code knowledge to deal with all fields without knowing them in advance, by accessing them with their name. this is field for example:
<!-- Email -->
<div class="form-group" data-ng-class="{ 'has-error' : step1Form.email.$invalid && (!step1Form.email.$pristine || submitted) }">
<label>Email</label>
<input type="email" name="email" class="form-control" data-ng-model="user.email" required data-ng-minlength="5" data-ng-maxlength="60">
<p data-ng-show="step1Form.email.$error.required && (!step1Form.email.$pristine || submitted)" class="help-block">required!</p>
<p data-ng-show="step1Form.email.$error.minlength" class="help-block">too short1</p>
<p data-ng-show="step1Form.email.$error.maxlength" class="help-block">too long!</p>
<p data-ng-show="step1Form.email.$error.email" class="help-block">invalid email!</p>
<p data-ng-show="step1Form.email.$error.serverError" class="help-block">{{emailServerError}}</p>
</div>
like you can see, the variable emailServerError is saved for errors that come from the server validations... i have a lot fields in my application and i try to write generic code that will fit for all the fields...
so this is the angular code:
// function to submit the form after all validation has occurred
$scope.submitForm = function() {
// check to make sure the form is completely valid
if ($scope.step1Form.$valid) {
// now we will go to server side validation
// AJAX calls.......
// lets say we got this back:
var problem = { field: 'email', msg: 'this email is already registered'};
// now we need to setValidity for email input.
var errorVariableName = $parse(problem.field + 'ServerError'); // Get the name of the error string variable.
errorVariableName.assign($scope, problem.msg); // Assigns a value to it
console.log($scope.emailServerError); // = 'this email is already registered'
// HERE THE PROBLEM:
// now i need to do something like that:
// $scope.step1Form. + problem.field + .$setValidity('serverError', false);
// but i dont know how to this that.
// i think that i need to get this element ($scope.step1Form. + problem.field) in some way by name, and then use setValidity on it. but i dont know how..
}
};
the question is in the comments inside the code...
