Get column index from column name in Kendo grid in Javascript

Is there a way we can find out the index of column in grid, if we know the column name in Kendo grid?

e.g. 

EmployeeID| Name
123       | John

I want to know the index of 'Name' field i.e. 1 in the grid. Any suggestions.

Thanks.

                    if (columns[i].field == strName) { // columns[i].title -- You can also use title property here but for this you have to assign title for all columns
                        index = i;
                    }
                }

            if (index == -1) {

            else {
                alert("column index is:- " + index);
            }
        }
    </script>
</body>
