未知提供程序: 使用 AngularJS 的 $modalProvider <-$modalerror

小开

最佳答案

This kind of error occurs when you write in a dependency for a controller, service, etc, and you haven't created or included that dependency.

In this case, $modal isn't a known service. It sounds like you didn't pass in ui-bootstrap as a dependency when bootstrapping angular. angular.module('myModule', ['ui.bootstrap']); Also, be sure you are using the latest version of ui-bootstrap (0.6.0), just to be safe.

The error is thrown in version 0.5.0, but updating to 0.6.0 does make the $modal service available. So, update to version 0.6.0 and be sure to require ui.boostrap when registering your module.

Replying to your comment: This is how you inject a module dependency.

<!-- tell Angular what module we are bootstrapping -->
<html ng-app="myApp" ng-controller="myCtrl">

js:

// create the module, pass in modules it depends on
var app = angular.module('myApp', ['ui.bootstrap']);


// $modal service is now available via the ui.bootstrap module we passed in to our module
app.controller('myCtrl', function($scope, $uibModal) {


});

Update:

The $modal service has been renamed to $uibModal.

Example using $uibModal

// create the module, pass in modules it depends on
var app = angular.module('myApp', ['ui.bootstrap']);


// $modal service is now available via the ui.bootstrap module we passed in to our module
app.controller('myCtrl', function($scope, $uibModal) {
//code here
});

Just an extra side note for an issue I also experienced today: I had a similar error "Unknown provider: $aProvider" when I turned on minification/uglify of my source code.

As mentioned in the Angular docs tutorial (paragraph: "A Note on Minification") you have to use the array syntax to make sure references are kept correctly for dependency injection:

var PhoneListCtrl = ['$scope', '$http', function($scope, $http) { /* constructor body */ }];

For the Angular UI Bootstrap example you mention you should this replace this:

var ModalInstanceCtrl = function ($scope, $modalInstance, items) {
/* ...example code.. */
}

with this array notation:

var ModalInstanceCtrl = ['$scope', '$modalInstance', 'items', function ($scope, $modalInstance, items) {
/* copy rest of example code here */
}];

With that change my minified Angular UI modal window code was functional again.

var ModalInstanceCtrl = ['$scope', '$modalInstance',  function ($scope, $modalInstance, items) {
/* copy rest of example code here */
}];

5 years later (this would not have been the problem at the time):

The namespacing has changed - you may stumble across this message after upgrading to a newer version of bootstrap-ui; you need to refer to $uibModal & $uibModalInstance.

The obvious answer for the provider error is the missing dependency when declaring a module as in the case of adding ui-bootstrap. The one thing many of us do not account for is the breaking changes when upgrading to a new release. Yes, the following should work and not raise the provider error:

var app = angular.module('app', ['ui.router', 'ngRoute', 'ui.bootstrap']);
app.factory("$svcMessage", ['$modal', svcMessage]);

Except when we are using a new version of ui-boostrap. The modal provider now is defined as:

.provider('$uibModal', function() {
var $modalProvider = {
options: {
animation: true,
backdrop: true, //can also be false or 'static'
keyboard: true
},

The advise here is once we have make sure that the dependencies are included and we still get this error, we should check what version of the JS library we are using. We could also do a quick search and see if that provider exists in the file.

In this case, the modal provider should now be as follows:

app.factory("$svcMessage", ['$uibModal', svcMessage]);

One more note. Make sure that your ui-bootstrap version supports your current angularjs version. If not, you may get other errors like templateProvider.

hope it helps.

after checking that I had all dependancies included, I fixed the issue by renaming $modal to $uibmodal and $modalInstance to $uibModalInstance
