控制器'ngModel'，由指令所要求的“...”，无法找到 [英] Controller 'ngModel', required by directive '...', can't be found

问题描述

这是怎么回事？

下面是我的指令：

  app.directive（'submitRequired'，函数（objSvc）{
    返回{
        要求：'ngModel'，
        链接：功能（范围，榆树，ATTRS，CTRL）{          // 做一点事
        }
    };
}）;
 

下面是使用中的指令的一个例子：

 ＆LT;输入提交要求的=真正的＆GT;＆LT; /输入＆GT;
 

下面是实际的错误文本：

解决方案

如下所述：角NgModelController ，您应该提供＆LT;输入与所需的控制器ngModel

 ＆LT;输入提交要求的=真正的NG-模式=user.Name＆GT;＆LT; /输入＆GT;
 

What's going on here?

Here is my directive:

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

          // do something
        }
    };
});

Here is an example of the directive in use:

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

Here is the actual error text:

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

解决方案

As described here: Angular NgModelController, you should provide the <input with the required controller ngModel

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