java script calculation in tabular form

Today i found very interesting Question on Apex forum

Question:

Java script Calculation in Tabular form apex oracle 5.0

So, basically it something like there are multiple columns and each column will have numeric and character values.We need to calculate numeric values and give its particular output(result).

Java script:

1. sal=  (parent_row.find('input[name=f05]').val().replace(/,/g,'') == ' ') ? 0 : 
2. parseFloat(parent_row.find('input[name=f05]').val().replace(/,/g,'') );     

Everything else remain same.
