删除上一个父元素

Question

我需要有关jquery的帮助。 我想在推动<img class='deletework">从<img class='deletework">删除标签<input type="text" hidden="true" value="1" required="true" name="countWorks"></input> 。我尝试$('.deleteWork').click(function() { $(this).parent().parent().parent().parent().prev().remove(); });但它是行不通的。

<td align="center">
<b></b>
<input type="text" hidden="true" value="0" required="true" name="countWorks"></input>
<input type="text" hidden="true" value="1" required="true" name="countWorks"></input>
<table class="raw_inside2" width="100%" border="0" style="margin:0.3em 0.1em;">
    <tbody>
        <tr>
            <th class="rowD" width="10%" title="Work types">
               Work types
            </th>
            <th class="rowD" width="10%" title="Power">
                Power
            </th>
        </tr>
        <tr class="rowW">
            <td>
                <input type="text" value="Frezing" required="true" name="ManMnf"></input>
            </td>
            <td>
                <input type="text" value="150" required="true" name="DSELbr"></input>
            </td>
            <td align="center">
                <img class="deleteWork" title="Delete work type" src="../imglib/icon/del.gif"></img>
            </td>
        </tr>

尝试使用.closest().parent().find("input[name=countWorks]").eq(1)

 $("img.deleteWork").click(function() { $(this).closest("table").parent().find("input[name=countWorks]").eq(1) .remove() }) 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script> <table> <tbody> <tr> <td align="center"> <b></b> <input type="text" hidden="true" value="0" required="true" name="countWorks" /> <input type="text" hidden="true" value="1" required="true" name="countWorks" /> <table class="raw_inside2" width="100%" border="0" style="margin:0.3em 0.1em;"> <tbody> <tr> <th class="rowD" width="10%" title="Work types"> Work types </th> <th class="rowD" width="10%" title="Power"> Power </th> </tr> <tr class="rowW"> <td> <input type="text" value="Frezing" required="true" name="ManMnf" /> </td> <td> <input type="text" value="150" required="true" name="DSELbr" /> </td> <td align="center"> <img class="deleteWork" title="Delete work type" src="../imglib/icon/del.gif" /> </td> </tr> </tbody> </table> </tr> </tbody> </table>

为什么不给它一个ID，用jquery选择它并以这种方式删除它呢？ 似乎您每次在区域中修改html时都必须重写当前的选择器。

<input id="myCounter" type="text" hidden="true" value="1" required="true" name="countWorks"></input>

$('#myCounter').remove();
