<!-- Include all compiled plugins (below), or include individual files as needed -->
<script src="../assets/js/bootstrap.min.js"></script>

</body>
</html>

```

And this js file (validation.js):

```
jQuery(function(){
    $('#loginForm').validate({
        rules: {
            loginEmail: {
                required: true
            }
        }
    });
});

```

And here are my included files:

```
    <script src="../assets/js/jquery-1.9.0.js"></script>
    <script src="../assets/js/jquery.validate.js"></script>
    <script src="../assets/js/validation.js"></script>

```

I do not get any errors about not loading files.
But i do get error about Object [object Object] has no method 'validate' . Anybody knows why?
