get RowIndex of Grid from a checkbox

I'm trying to get the row index of my checkbox, the current code i can get the checked value of the checkbox. the closest doesn't work and i'm stack. If i check a box on grid row 1 an alert should shows 1

        $(":checkbox").change(function () {
            if ($(this).is(':checked')) {
                var id = $(this).closest("tr");

                alert(id.innerText);


            } else {
                alert("Failed");
            }
        });

EDIT: iv'e added this line

var $id = $(this).closest("tr");
   alert($id.index() + 1)
   var table = document.getElementById("tblSearchLogs");
   var appid = table.rows[$id].cells[1].innerText

But it gives me an error

0x800a138f - JavaScript runtime error: Unable to get property 'cells' of undefined or null reference

InnerText is for getting and setting text property of element. Also its not working here as you are calling it on jquery object of element and not DOM element.

You need to use index of element here:

 var $id = $(this).closest("tr");
 alert($id.index() + 1); // as index starts from 0
