如何获取动态控件里的值

Question

如上图
页面加载时只有两行，但是当用户填写最后一行时会自动增加一行，以此类推，
现在怎样获得那些控件的值
那些动态生成的控件是JS生成的不是后台生成的？
页面代码如下
<tr>
                    <td>
                        <input id="c1-1" type="hidden" value="0" /><input id="c1-2" type="hidden" value="" /><input
                            id="c1-3" type="hidden" value="" /><div class="uploadphoto" onclick="productview_OpenUpdateImage(this)">
                            </div>
                        <a href="image/button_update_product_photo.gif" title="打开图片" target="_blank">
                            <img src="image/button_update_product_photo.gif" /></a>
                    </td>
                    <td class="input_No">
                        <input id="c1-4" onchange="productview_inputChange(this);productview_nocin(this)"
                            type="text" value="" />
                    </td>
                    <td class="input_Intro">
