Question

我在控制器中有这段代码

app.controller('Ctrl', function($scope, $invalid, $location) {
$scope.upd_check = function()
    {
        console.log($scope.MyForm);
        if($scope.MyForm.$invalid){
            $("#modal_traffic_incorrect").modal('show');
        }

    }

我的HTML代码是

 <form name="MyForm">
          <div class="item_title">Text</div>
          <div class="item_contentbox">
            <input class="inputs len_md" name="number" ng-model="text" ng-required ng-pattern="/^([1-9])$/"   >

          </div><br />
<div class="col-md-offset-1 col-md-10 col-sm-12 text_right">
                <button type="submit" class="button" ng-click="upd_check()">Save</button><br><br><br>
          </div>
        </form>

        </div><br />

我收到此错误：错误：[$ injector：unpr] http://errors.angularjs.org/1.4.8/ $ injector / unpr？p0 = NaNnvalidProvider％20％3C-％20％24invalid％20％3C-％20Ctrl

我怎么能想解决这个问题？谢谢你的帮助

Error: $injector:unpr

This error results from the $injector being unable to resolve a required dependency. To fix this, make sure the dependency is defined and spelled correctly. For example:

angular.module('myApp', [])
.controller('MyController', ['myService', function (myService) {
// Do something with myService
}]);

The above code will fail with $injector:unpr if myService is not defined.

Making sure each dependency is defined will fix the problem, as noted below.

angular.module('myApp', [])
.service('myService', function () { /* ... */ })
.controller('MyController', ['myService', function (myService) {
// Do something with myService
}]);

so for your part, try:

app.controller('Ctrl', ['$scope','$invalid','$location',function($scope,$invalid, $location) 
{}];

错误：[$ injector：unpr] http://errors.angularjs.org/1.4.8/$injector/unpr?p0=NaNnvalidProvider%20%3C-%20%24invalid%20%3C-%20Ctrl
