Javascript AJAX-如何在弹出菜单中运行脚本

我有一个弹出菜单，可以打开并显示当前的文本。我想要的是能够将控制器连接到弹出菜单。例如：我希望显示一个编辑配置文件弹出窗口，其中包含编辑配置文件所需的所有输入

userprofile_view.php：

        <div class="upload">
    <?php
        $data = array('id' => 'test'); 
        echo form_open('', $data); 
        echo form_submit('upload', 'Upload'); 
        echo form_close(); 
    ?>
    </div>      
<div id="popupbox">     
            <center>
                <p class="head">Terms and Conditions</p>

                <p class="term_full">By entering your email, you allow Musiclear to send you information regarding Musiclear and 
                    related services <br><br> By entering your email, you also understand that you can break our hearts and unsubscribe 
                    at anypoint.  <br><br> And feel free kick us if we ever share your email address (you can trust us)</p>
            </center>

        </div> 

在按钮上单击“我使窗体可见”

如何使用弹出菜单中的表单使其工作

编辑：

上传控制器（我想在弹出窗口中显示的内容）：

userprofile_view.php（popubox）：

将函数调用放在脚本标记内-

<div id="popupbox">

    <?php 
        echo '<script type="text/javascript">';
        echo "form_open_multipart('upload/do_upload_profilepicture');";
        echo '</script>';
    ?>
    <input type="file" name="userfile" size="20" />
    <br /><br />
    <input type="submit" value="upload" />
    </form>
</div> 

优化这个？这不需要优化。您是在问如何向弹出窗口添加功能吗？很抱歉，是的，措辞错误。我想更改一下，向弹出窗口添加功能与添加事件处理程序没有什么不同，就像您为
#test
所做的一样。现在可以工作了！：D谢谢。如果你愿意，你可以发布一个答案，我会投票决定并接受它。Divergent@itDone-很高兴能帮你找到答案。
function do_upload_profilepicture()
{

$this->load->model('model_users');
$userID = $this->model_users->getUserID($this->session->userdata('username'));

$config['upload_path'] = './img/profilepictures/';
