how to login with ajax

[rjusman90]

I am quite new to JS and AJAX and I am having a hard time understanding what the other person has implemented and how I can get it to function properly.

this is my login CI code that is working perfectly, but now i want to do it with ajax
`class Login extends Admin_Controller
    {

    public function index()
        {
            if ( $this->session->userdata('user'))
            {
                return redirect('admin/dashboard');
            }
            $this->form_validation->set_rules('txtemail','Email','required');
            $this->form_validation->set_rules('txtpassword','Password','required');
            if ($this->form_validation->run() == TRUE)
            {
                $username = $this->input->post('txtemail');
                $password = $this->input->post('txtpassword');
                $query = $this->database_model->GetRecord('cms_users', false, array('EmailAddress' => $username, 'Password' => $password));
                if ($query == false) {
                    $this->session->set_flashdata('display_msg', 'Invalid Username/Password.');
                    return redirect('admin/login');
                } else
                {
                    $this->session->set_userdata('user', $query);
                    return redirect('admin/dashboard');
                }
            }else
            {
                $this->load_view('admin/login');
            }

        }
    }`
    and this is my js
    `var options = {
    success:    function() {
        window.location = 'admin/master_templete';
    },
    error:    function() {
        alert('Thanks for error comment!');
    }
};
$(document).ready(function(){
$('#form_login').validate({
        errorElement: 'span',
        errorClass: 'error',
        focusInvalid: false,
        ignore: "",
        rules: {
            email: {
                required: true,
                email: true
            },
            password: {
                required: true
            }
        },
        messages: {
            email: 'Please enter email address',
            password: 'Please enter password'
        },

        errorPlacement: function (error, element) { // render error placement for each input type
            error.insertAfter(element.next());
        },

        submitHandler: function (form,status) {
            $('#form_login').ajaxSubmit(options);
            return false;
        }

    });
});
`
