  $scope.updateFunction = function(updateId) {
    $http.get("http://localhost/crud/public/registration_update_page/" + updateId).then(function successCallback(response) {
      console.log('successCallback');
      console.log(response);
      alert("Row with id " + updateId + ", updated..!");
    }, function errorCallback(response) {
      console.log('errorCallback');
      console.log(response);

    I solved this problem myself This works for ANGULAR.JS with Laravel 4 to run insert,update,delete and select queries of the MySql DataBase.

    VIEW

    <!DOCTYPE html>
<html>
<head>
  <script src="http://ajax.googleapis.com/ajax/libs/angularjs/1.4.8/angular.min.js"></script>

</head>
<body ng-app="myApp" ng-controller="myCtrl">

<h2>Registration</h2><br/>
<table border=1>
<tr><td>Name:</td><td><input type="text" ng-model="nam" name="nam"><br/></td></tr>
<tr><td>Email:</td><td><input type="email" ng-model="email" name="email"><br/></td></tr>
<tr><td>Password:</td><td><input type="password" ng-model="password" name="password"><br/></td></tr>
<tr><td>City:</td><td><input type="text" ng-model="city" name="city"><br/></td></tr>
<tr><td><button ng-click="insertFunc()" type="submit">Submit</button></td></tr>
</table>

</div>
</form>

<table style="width:100%" border=1>
  <tr>
    <th>Id</th>
    <th>Name</th>
    <th>Email</th>
    <th>Password</th>
    <th>City</th>
    <th>Update</th>
    <th>Delete</th>

  </tr>

  <tr ng-init='show = true' ng-repeat="x in query" ng-hide='!show'></div>
    <!-- ng-hide will work when it is true in condition -->
    <td>{{x.id}}</td>
    <td>{{x.name}}<input type="text" ng-model="edited_name"></td>
    <td>{{x.email}}<input type="text" ng-model="edited_email"></td>

    <td><input type="submit" ng-click="updateFunction(x.id,edited_name,edited_email,edited_password,edited_city);" value="Update"></td>
    <td><button ng-click="deleteFunction(x.id);show = false">Delete</button></td>

    | Here is where you can register all of the routes for an application.
    | It's a breeze. Simply tell Laravel the URIs it should respond to
    | and give it the controller to call when that URI is requested.
    |
    */

    Route::get('/', function () {
        return view('welcome');
    });

    Route::auth();

Route::get('/registration', 'NewController@registration_function');

Route::post('/registration_data_page', 'NewController@registration_data_function');

Route::get('/registration_json_page', 'NewController@registration_json_function');

Route::get('registration_delete_page/{id}', 'NewController@registration_delete_function');

Route::get('registration_update_page/{id}/{edited_name}/{edited_email}/{edited_password}/{edited_city}', 'NewController@registration_update_function');
