如何在codeigniter的控制器中调用javascript函数？

snailslowdx_619 发布于 2023-02-08 23:55

css

function

require

xss

我有这样的看法

//at this div have css .alert{display:none;} X oops! username atau password yang anda masukan salah

在我的控制器里

public function login_form() {
    $this->form_validation->set_rules('username', 'Username', 'required|trim|xss_clean');
    $this->form_validation->set_rules('password', 'Password', 'required|md5|xss_clean');
    $this->form_validation->set_error_delimiters('', '');

    if($this->form_validation->run()==FALSE) {
        $this->load->view('v_admin_login');
    } else {
        $username = $this->input->post('username');
        $password = $this->input->post('password');

        $cek = $this->m_admin_login->getAdmin($username, $password, 1, 1);

        if($cek <> 0) {
            $this->session->set_userdata('isLogin', TRUE);
            $this->session->set_userdata('username',$username);
            $this->session->set_userdata('level',$level);

            redirect('admin');
        } else {
            //I want to change class alert to .alert{display:block}
            //What should I do?
        }
    }
}

关键是我想在输入用户名或密码错误的情况下用class alert显示div.

打印javascript代码就像使用ECHO命令的字符串一样,但不要忘记放置标记.看我的例子:

<?

class Test extends CI_Controller {

    function Test() {
        parent::__construct();

    }

    function index() {

        echo "<script language=\"javascript\">alert('test');</script>";
    }
}
