How to Disable Not modified validation for specific fields

[manosingh]

I have a custom field , each time when i edit that field i change the value of that field to 0 using javascript , in view page it will show the actual db value.

Now in edit page if user tries to give the same db value then it shows a warning message 'You have not modified any changes'

How to ignore this warning for specific field i need user to update with same value again in the edit page.

Let me know if any solution there . Thanks in Advance
