有没有办法使用javascript访问gridview中复选框的选中值

Question

So I have a template field with a checkbox and a hidden field in it.

 <asp:TemplateField>
    <ItemTemplate>
       <asp:CheckBox runat="server" ID="chkAdd" />
       <asp:HiddenField runat="server" ID="hfValue" Value='<%Item.SomeValue%>'/>
    </ItemTemplate>
 </asp:TemplateField>

Using javascript, I want to able to look through to see which checkboxes are checked and get the corresponding value stored in the the HiddenValue control.

I know how to loop through the rows of a gridview and get a cell's innerText. How would I go about getting a checkbox's checked and a hidden field's value?

IF you want to find hidden field value from gridview on check changed of check box of gridview by javascript then you can use like below function.

   function IAmSelected(source, eventArgs) {
                if (source) {
                    // Get the HiddenField ID.
                    var hiddenfieldID = source.get_id().replace("chkAdd", "hfValue");// here you can add any control of your gridview row which value you want
                    $get(hiddenfieldID).value = eventArgs.get_value();
                }
      }
