我想在控制器（CI）中创建一个确认框。我该怎么做？我知道在view.php文件中写javascript确认但是现在我有会话并在点击提交按钮的最后提交表单上验证为null或有效。所以，我需要在CI控制器功能中进行确认对话。请帮帮我。
这是我的观看代码。
<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>
这是我的提交完成表单控制器功能代码。

答案 0 :(得分：0)
在控制器功能
中尝试此操作echo "<script language=\"javascript\">confirm('confirm box');</script>";
这可以帮到你
$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;
