Error: Unknown provider: $elementProvider <- $element

routing angularjs

~~$element is not injectable (it is not something that is registered with the AngularJS injector), so you can't pass it into your controller that way.~~

Your productsCtrl, and hence your search() method, has access to all of the form data because of the ng-model directives, which setup two-way binding between your form and your controller. E.g., inside your search() method, you already have access to the keywords as $scope.keywords.

See if this works for you:

var dt = $($scope.keywords).serialize();  // or maybe just  $scope.keywords.serialize();

Update: this fiddle http://jsfiddle.net/michelpa/NP6Yk/ seems to inject $element into a controller. (I'm not sure how/why that works... maybe because the controller is attached to a form tag/directive?)

Update #2: injecting $element into a controller is possible, but that "goes deep against the angular way" -- https://groups.google.com/d/msg/angular/SYglWP_x7ew/lFtb75NWNWUJ

As mentioned in the comments, I think the answer to your question is to put your form data into a single, larger object and send that along in your $http request.

i am trying to use routing in angularjs application as follows:

app.js

    angular.module('productapp', []).
    config(['$routeProvider', function($routeProvider) {
    $routeProvider.
        when('/productapp', {templateUrl: 'partials/productList.html',   controller: productsCtrl}).
        //~ when('/productapp/:phoneId', {templateUrl: 'partials/phone-detail.html', controller: PhoneDetailCtrl}).
        otherwise({redirectTo: '/productapp'});
}]);

controller.js

function productsCtrl($scope, $http, $element) {
        //~ $scope.url = 'php/search.php'; // The url of our search
        // The function that will be executed on button click (ng-click="search()")
        $http.get('php/products.php').success(function(data){
            alert("hi");
            $scope.products = data;
        });

    $scope.search = function() {
        var elem = angular.element($element);
        var dt = $(elem).serialize();
        dt = dt+"&action=index";
        alert(dt);
        console.log($(elem).serialize());
        $http({
            method: 'POST',
            url: 'php/products.php',
            data: dt,
            headers: {'Content-Type': 'application/x-www-form-urlencoded'}
        }).success(function(data, status) {
            //console.log(data);
            $scope.products = data; // Show result from server in our <pre></pre> element
        }).error(function(data, status) {
            $scope.data = data || "Request failed";
            $scope.status = status;
        });
    }; //....

<div>
            <label>Search</label>
            <input type="text" name="searchKeywords" ng-model="keywords" placeholder="enter name..." value="{{rs.name}}">
            <button type="submit" ng-click="search()">Search</button>
            <label>Add New Product:</label>
            <input type="text" name="keywords" ng-model="rs.name" placeholder="enter name..." value="{{rs.name}}">
            <input type="text" name="desc" ng-model="rs.description" placeholder="enter description..." value="{{rs.description}}">

            <button type="submit" ng-click="save(rs.product_id)">Save</button>

            <p>enter product name...</p>
            <table border='2'>
                <th>Name</th>
                <th>Description</th>
                <th>Edit</th>
                <th>Delete</th>

                <tr ng-repeat="product in products" ng-model = 'products'>
                <td>{{product.name}}</td>
                <td>{{product.description}}</td>
                    <td><a href='' ng-click = "fetch(product.product_id)">edit</a></td>
                    <td> <a href='' ng-click = "del(product.product_id)" ng-hide="isHidden">delete</a></td>
                </tr>
            </table>
</div>

when i run this code i get the following error in the console(of google chrome) :

Error: Unknown provider: $elementProvider <- $element

i came to know that this error occurred because i am using the $element in the productsCtrl. but then what should i do? how do i solve this problem?

keywords is the name of just one textbox. i use $element as i want to serialize the content of all the form fields. if i use $scope.field then i have to specify all the fields manually. is there any other way round?

Reading around, it seems you shouldn't have to use jQuery's serialize() method at all. See if these help (note that $xhr was replaced with $http): groups.google.com/d/msg/angular/ySpF18OiETo/uyKCM1oWknAJ and deansofer.com/posts/view/14/… -- here Dean suggests putting all your form data into a larger object, hence <input type="text" name="searchKeywords" ng-model="data.keywords"

thanks mate! solution given in groups.google.com/forum/#!msg/angular/ySpF18OiETo/uyKCM1oWkn‌AJ works. i used $(elem.parent()).serialize() to make it work.

yeah, that would not be a very "angular" way of doing things. I would have a model containing an array of objects and for each of those ng-foreach generate the form elements, then just serialize the object.

Does that really work for you? It doesn't work for me.
