如何使用jQuery计算GridView内部下拉菜单中的选定选项

问题描述

我在gridview中有几个下拉菜单，每个下拉菜单都有2个相同的选项，我想从所有这些下拉列表中计算出option1被选择的次数(selectedIndex = 1)以及第二个选项被选择的次数(selectedIndex = 2)使用jQuery.

I have a few dropdowns in my gridview, each has 2 same options, I want to calculate out of all these dropdowns how many times is option1 selected (selectedIndex = 1) and how many times the second option is selected (selectedIndex = 2) using jQuery.

   <asp:GridView ID="gd1" runat="server" AutoGenerateColumns="False"
           onrowdatabound="gd1_RowDataBound" >
           <Columns>
                      <asp:BoundField DataField="id"   Visible="False"/>
                      <asp:BoundField DataField="fullName" Visible="True"
           HeaderText="Full Name"/>
                         <asp:TemplateField >
                             <ItemTemplate>
    <asp:DropDownList ID="ddl1" runat="server" ></asp:DropDownList>
                           </ItemTemplate>
                         </asp:TemplateField>

                         <asp:TemplateField >
                             <ItemTemplate>
    <asp:DropDownList ID="ddl2" runat="server"></asp:DropDownList>
                           </ItemTemplate>
                         </asp:TemplateField>

                         <asp:TemplateField >
                             <ItemTemplate>
    <asp:DropDownList ID="ddl3" runat="server"></asp:DropDownList>
                           </ItemTemplate>
                         </asp:TemplateField>

                         <asp:TemplateField>
                             <HeaderTemplate>
             <asp:Label ID="Count1" runat="server" Text="First Count"></asp:Label>
                             </HeaderTemplate>
                             <ItemTemplate>
             <asp:Label ID="CountSelected1" runat="server" ></asp:Label>
                             </ItemTemplate>
                         </asp:TemplateField>

                         <asp:TemplateField>
                             <HeaderTemplate>
          <asp:Label ID="Count2" runat="server" Text="Second Count"></asp:Label>
                             </HeaderTemplate>
                             <ItemTemplate>
              <asp:Label ID="CountSelected2" runat="server" ></asp:Label>
                             </ItemTemplate>
                         </asp:TemplateField>
          </Columns>
</asp:GridView>

在最后两列中，我想显示option1和option2的选择总数.

In the final 2 columns I want to display the total number of selections of option1 and option2.
