DataGrid要实现这样的功能，要用到JS，求助?

Question

在DataGrid中最左边是一模板列,一组checkbox
<asp:TemplateColumn>
<ItemTemplate>
<asp:CheckBox ID="chk" Runat="server" style="CURSOR:hand;background-Color:#99ccff" tooltip="选择接口"></asp:CheckBox>
</ItemTemplate>
</asp:TemplateColumn>最右边也一模板列是一组超链接,单击用window.open新打开一个窗口
<asp:TemplateColumn>
<ItemTemplate>
<a href="#" onclick='<%#FormatUrl( DataBinder.Eval( Container.DataItem,"id").ToString() )%>' title="定制字段信息">
[字段定义]</a>
</ItemTemplate>现在要实现这样的功能，当左边的复选框没选中时，对应那一行的右边超链接没用，只是显示文本
当选中时，让右边的超链接有用，怎么实现呢?
</asp:TemplateColumn>

<script language="javascript">
        function funcTest(obj)
        {
           var tmp = obj.id.replace('CheckBox1','HyperLink1');
           if(obj.checked)
                document.all[tmp].innerHTML = 'aaaaaaaaa';
                else
                document.all[tmp].innerHTML = '';
        }
        </script>

....
<asp:TemplateColumn>
                        <ItemTemplate>
                            <asp:CheckBox id="CheckBox1" runat="server" Text="AAAAA" onclick="funcTest(this);"></asp:CheckBox>
                        </ItemTemplate>
                    </asp:TemplateColumn>
                    <asp:TemplateColumn>
                        <ItemTemplate>
                            <a id="HyperLink1" href="#" runat=server></a>
                        </ItemTemplate>
                    </asp:TemplateColumn>

Answer 2

改进一下：
function funcTest(obj)
        {
           var tmp = obj.id.replace('CheckBox1','HyperLink1');
           if(obj.checked)
                document.all[tmp].style.display = 'inline';
           else
                document.all[tmp].style.display = 'none';
        }
