找不到指令“ ...”所需的控制器“ ngModel”

这里发生了什么？

这是我的指令：

app.directive('submitRequired', function (objSvc) {
    return {
        require: 'ngModel',
        link: function (scope, elm, attrs, ctrl) {
          // do something
        }
    };
});

这是使用中的指令的示例：

<input submit-required="true"></input>

这是实际的错误文本：

Error: [$compile:ctreq] Controller 'ngModel', required by directive 'submitRequired', can't be found!

回答：

如此处所述：Angular

NgModelController，您应提供<input所需的控制器ngModel

<input submit-required="true" ng-model="user.Name"></input>
