You have declared alertmsg outside controller function. Move it inside a myCntrl controller factory function. So basically because of $scope.alertmsg function kept outside $scope variable isn't defined, that's why JS compiler yelling there. And further statement aren't get executed. Since myService service doesn't get register in myApp angular module and it says myService unknown provider
http://errors.angularjs.org/1.6.5/ $injector/unpr?p0=myServiceProvider%20%3C-%20myService
var app = angular.module("myApp", [])
.controller("myCntrl", function ($scope, myService) {
$scope.LoginCheck = function () {
//code as is
}
function clearFields() {
$scope.uName = '';
$scope.uPwd = '';
}
//move this function inside `myCntrl` controller function.
$scope.alertmsg = function () {
$("#alertModal").modal('hide');
};
});
Apart from angularjs errors, you have fix all the error appearing in console. Likewise load
jQuerybeforebootstrap.js
