<tr>
<td>
                        <div class="line">
                            <div class="div_id"><span id="GridView1_ctl08_id">37</span></div>
                            <div class="div_jap"><span id="GridView1_ctl08_japanese" class="japanese">はし</span></div>
                            <div class="div_kuohao"><span id="GridView1_ctl08_chinese">(</span></div>
                            <div class="div_chn"><span id="GridView1_ctl08_Label1"></span></div>
                            <div class="div_kuohao"><span id="GridView1_ctl08_Label2">)</span></div>
                        </div>
                        <div>
                  &nbsp;&nbsp;<span id="GridView1_ctl08_A" class="option" style="display:inline-block;width:10px;">A.</span>

                        </div>
                    </td>
</tr>
我需要点击GridView1_ctl08_answer1，<span id="GridView1_ctl08_Label1">获取GridView1_ctl08_answer1的值，并显示。function choiceAnswer(obj)
{
    $yourChoice=$(obj).val();
    $(".div_chn",$(obj).parent().parent()).val=$yourChoice;
}
我是这样写的，好像错了，请问该怎么写？

Answer 1

$(".div_chn",$(obj).parent().parent()).val($yourChoice); 

Answer 2

是把GridView1_ctl08_answer1的内容赋给GridView1_ctl08_Label1吧
$yourChoice=$("GridView1_ctl08_answer1").text();
$("#GridView1_ctl08_Label1").text($yourChoice); 

Answer 3

不行啊 $yourChoice=$(obj).val();这句有问题啊
$yourChoice是空的，没有值？

Answer 4

当然有问题了 
你没看我用的是text()么
