如何从指令中的ng-model获得价值？

Question

我有代码：

<input check-value-type-array type-value="node.type_value" type-element="node.type" ng-value="item" class="form-control">

指令：

.directive('checkValueTypeArray', function() {
         return {

             restrict: 'A',
             require: 'ngModel',
             scope: {
                 typeElement: '=',
                 typeValue: '=',
                 ngModel: '='
             },

             link: function(scope, element, attrs, ngModel) {


                 ngModel.$validators.required = function(v) {}

             }

如何获取ng-model inside指令并进行验证：

ngModel.$validators.required = function (v) {
}

Answer 1

轻微改动，你正在寻找ngModel。$ modelValue：

ngModel.$validators.required = (value) => {
  // the value of the model will be ngModel.$modelValue
}
