我想在控制器（CI）中做一個確認框。我應該怎麼做？我知道在view.php文件中寫javascript確認，但現在我有會話，並在點擊提交按鈕的最後提交表單上驗證爲空或有效。所以，我需要確認對話框進入CI控制器功能。請幫幫我。如何在codeigniter控制器中使用javascript確認？
這是我的視圖代碼。
<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>
這是我的提交完成表格控制器功能代碼。

顯示控制器代碼 - 或@least到目前爲止，你已經嘗試過什麼，恕我直言，你可以隨時使用一個視圖或一個js文件，無論如何;） – sintakonte
我更新了我的問題。請檢查我的代碼。在那個函數中有來自整個項目的會話數據，我想檢查該控制器中的會話數據，並使確認框提交或不提交。 –
