如何在Codeigniter控制器中使用JavaScript确认？

Question

I want to make a confirm box in controller (CI). How should i do that? I know to write javascript confirm in view.php file but for now i have sessions and validate to null or valid at the last submit form on click submit button. So, I need to make confirm dialog into CI Controller function. Please help me.

Here is my view code.

<div align="center" class="col-md-9" id="label">
   <form method="post" id="formsubmit1" name="formsubmit1" action="{base_url('home/completionform')}" enctype="multipart/form-data">
     <div class="form_block">       
        <p class="question">
        You can now submit that you answered above or you can continue to answer next questions.
        </p>
           <br>
             <input type="submit" name="submit" class="btn btn-default nextbutton" id="btn_submit" value="Submit" onclick="completionform();" />
        <a href="{base_url('home/question5')}" class="btn btn-default">Continue</a>
     </div>
    </form>
</div>

Here is my submit completion form controller function code.

public function completionform()
{

    $sess_data=$this->session->userdata();
    $ses_key = key($sess_data);
    if (empty($sess_data['user_info']))

        echo "Session has been destroyed~!";
    }
    else
    {
        $user_info = ($sess_data['user_info']);

        if (!empty($sess_data['question5']))

Answer 1

try this in controller function

echo "<script language=\"javascript\">confirm('confirm box');</script>";

this can help you

$this->load->library('session');
$result = $this->your_model->user_ques($question);
if ($result) {

    foreach ($result as $ans)
    {
        $sess_array = array(
            'full_name' => $ans->full_name,
            'catagory' => $ans->catagory,
            );
        $this->session->set_userdata('logged_in', $sess_array);
    }
    return TRUE;
