How to get imagebuttonId in a gridview using jquery

I have resolved the issue using the following function:

Note:
appBtn is the css class name assigned to the button
Gvplacement  is the css class name assigned to  the gridview.
   

Please find below my code:

   function fReceiptExists() {
        var totalreceiptcount;
        var len = $("input:checkbox:checked").length;
        if (len == 0) {
            alert("Please select any timesheet for approval");
              return false;
            }
            else {
                 $('#<%=ExpensesGridView.ClientID%>').each(function() {

                    if ($(this).find('input:checkbox').attr("checked")) {
                        alert('inseide');


                        totalreceiptcount += parseInt($(this).find('input:text[id$="lblReceiptCount"]').attr("value"));
                        alert(totalreceiptcount);
                    }
                 
                });
       
            return true;
        }
    }

can you please share your code to debug your issue? also tell me what is the error message you are getting.

Thanks for you quick response.

Now I am able to check whether check box are selected or not.

I have to find the sum of  label controls for which the check box are selected .

I tried using .each function but some error was throwing.
