无法find指令“…”所需的控制器'ngModel'

这里发生了什么？

这是我的指示：

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

这里是一个使用指令的例子：

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

以下是实际的错误文字：

 Error: [$compile:ctreq] Controller 'ngModel', required by directive 'submitRequired', can't be found! http://errors.angularjs.org/1.2.2/$compile/ctreq?p0=ngModel&p1=submitRequired at http://www.domain.ca/Scripts/angular/angular.js:78:12 at getControllers (http://www.domain.ca/Scripts/angular/angular.js:5972:19) at nodeLinkFn (http://www.domain.ca/Scripts/angular/angular.js:6139:35) at compositeLinkFn (http://www.domain.ca/Scripts/angular/angular.js:5550:15) at nodeLinkFn (http://www.domain.ca/Scripts/angular/angular.js:6132:24) at compositeLinkFn (http://www.domain.ca/Scripts/angular/angular.js:5550:15) at publicLinkFn (http://www.domain.ca/Scripts/angular/angular.js:5458:30) at http://www.domain.ca/Scripts/angular/angular.js:1299:27 at Scope.$get.Scope.$eval (http://www.domain.ca/Scripts/angular/angular.js:11634:28) at Scope.$get.Scope.$apply (http://www.domain.ca/Scripts/angular/angular.js:11734:23) <input submit-required="true"> angular.js:9159 (anonymous function) angular.js:9159 $get angular.js:6751 nodeLinkFn angular.js:6141 compositeLinkFn angular.js:5550 nodeLinkFn angular.js:6132 compositeLinkFn angular.js:5550 publicLinkFn angular.js:5458 (anonymous function) angular.js:1299 $get.Scope.$eval angular.js:11634 $get.Scope.$apply angular.js:11734 (anonymous function) angular.js:1297 invoke angular.js:3633 doBootstrap angular.js:1295 bootstrap angular.js:1309 angularInit angular.js:1258 (anonymous function) angular.js:20210 trigger angular.js:2315 (anonymous function) angular.js:2579 forEach angular.js:300 eventHandler angular.js:2578ar.js:7874 

Answer 1

如下所述： Angular NgModelController ，你应该提供<input与所需的控制器ngModel

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

Answer 2

这个问题的一个可能的解决scheme是使用该指令需要ng-model属性。

因此，添加'ng-model'属性可以解决问题。

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