javascript如何设置获取GridView模板列的值

Question

如题。

比如如下一个GridView 

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" 
        DataKeyNames="NewsID" DataSourceID="SqlDataSource1">
        <Columns>
            <asp:BoundField DataField="Title" HeaderText="Title" SortExpression="Title" />
            <asp:BoundField DataField="AddTime" HeaderText="AddTime" 
                SortExpression="AddTime"  DataFormatString="{0:yyyy-MM-dd}"/>
            <asp:BoundField DataField="AccountID" HeaderText="AccountID" 
                SortExpression="AccountID" />
            <asp:BoundField DataField="NewsID" HeaderText="NewsID" InsertVisible="False" 
                ReadOnly="True" SortExpression="NewsID" />
                <asp:TemplateField>
                <ItemTemplate>
                <asp:TextBox ID="txtbx" runat="server" Text='<%# Eval("AccountID") %>'></asp:TextBox>
                </ItemTemplate>
                </asp:TemplateField>
        </Columns>
    </asp:GridView>

 

我要用javascript获取txtbx的值，然后根据这个值做些修改。用什么能实现。谢谢各位啦。
