javascript - How to reduce the form validation fields in AngularJS -


i have form 3 input fields. want use form other pages. therefore have reduced form. @ beginning i've defined view follows:

view:

<form class="form-horizontal" name="editform" novalidate>   <div ng-repeat="elements in form">     <div class="form-group-sm has-feedback" ng-repeat="el in elements.items" ng-class="{ 'has-error' : haserror(editform), 'has-success' : hassuccess(editform) }">        <label class="control-label" for="{{el.id}}">{{el.label}}</label>        <input type="{{el.fieldtype}}"               class="form-control"                placeholder="{{el.label}}"                 name="{{el.name}}"                id="{{el.id}}"               ng-model="selected[el.model]"                ng-disabled="{{el.disabled}}"               ng-pattern="el.pattern"                ng-required="{{el.required}}"        />        <p class="help-block" ng-show="editform.{{el.name}}.$error.required && editform.{{el.name}}.$touched">field required.</p>        <p class="help-block" ng-show="editform.{{el.name}}.$error.pattern">thats pattern error message.</p>    </div>  </div>     </form>

i want outsource error messages / validation in function. error messages in p-tag don't work.

i've tried in ctrl:

$scope.haserror = function (form) {    return form.firstname.$invalid && form.firstname.$dirty; }  $scope.hassuccess = function (form) {    return form.firstname.$valid; }

that inputfield firstname. how can define dynamically fields (firstname, lastname, age)?

pass dynamic field name function:

ng-class="{ 'has-error' : haserror(editform, el.name), 'has-success' : hassuccess(editform, el.name) }"

and in controller use bracket notation access variable ngmodelcontroller:

$scope.haserror = function (form, name) {    return form[name].$invalid && form[name].$dirty; };  $scope.hassuccess = function (form, name) {    return form[name].$valid; };
