AngularJS 检查 Controller 中的表单是否有效

Question

我需要检查表单在 Controller 中是否有效。

查看:

<form novalidate=""
      name="createBusinessForm"
      ng-submit="setBusinessInformation()"
      class="css-form">
 <!-- fields -->
</form>

在我的 Controller 中:

.controller(
    'BusinessCtrl',
    function ($scope, $http, $location, Business, BusinessService, 
              UserService, Photo)
    {

        if ($scope.createBusinessForm.$valid) {
            $scope.informationStatus = true;
        }

        ...

我收到此错误:

TypeError: Cannot read property '$valid' of undefined

Answer 1

试试这个

View 中:

<form name="formName" ng-submit="submitForm(formName)">
 <!-- fields -->
</form>

在 Controller 中:

$scope.submitForm = function(form){
  if(form.$valid) {
   // Code here if valid
  }
};

或

View 中:

<form name="formName" ng-submit="submitForm(formName.$valid)">
  <!-- fields -->
</form>

在 Controller 中:

$scope.submitForm = function(formValid){
  if(formValid) {
    // Code here if valid
  }
};
