Get value from asp:RadioButton on mouseover

Question

I have a asp:RadioButton inside a asp:GridView:

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="false" GridLines="None">
 <Columns>
    <asp:TemplateField>
     <ItemTemplate>
      <asp:RadioButton ID="RB" runat="server" Text='<%#Eval("Name").ToString() %>' AutoPostBack="true"/>
     </ItemTemplate>
    </asp:TemplateField>
 </Columns>
</asp:GridView>

I can change the background-color like this:

$(function () {
 $("[id*=GridView1] td").hover(function () {
    $("td", $(this).closest("tr")).addClass("hover_row");
  }
});

but I don't know how to extract the value of the RadioButton on mouseover. I tried using the val() function but I always get 'undefined'

Answer 1

尝试

var myval = label[for='" + $(this).find("input:radio").attr("id") + "']").text();

Answer 2

我必须使用text（）而不是val（）：

$("td", $(this).closest("tr")).text();
