Is that possible to detect if a page goes back(history.back()) using javascript?

RE: history.back()

What exactly are you trying to do?  Are you trying to prevent someone going back to avoid accidental submission of the same form twice?  ...or... what?


RE: history.back()

I have 2 pages, input.asp & error.asp

input.asp has 3 textboxes.  When this page is first loaded, all textboxes are disabled.  They have to enable (press a button) and edit before submit.  

On top of input.asp, error checking is done.  If error(s) is/are found, the page is redirect

A back button is in error.asp.  So user can go back.  The good thing about the back(history.back() ) is that it retains old values.  I mean those erroneous input.  But the textbox are still disabled.  

How to enable those?..  I mean how to distinguish between page when it is first loaded and page that is (go back) from error.asp?

RE: history.back()

Do you need form elements on the input.asp page to be filled in with the values previously entered?

I am trying all sorts of tests and can't figure out anything right now.  

My instinct, then, is to make your 'back' button on the error.asp page call a function which actually goes forward, calling input.asp with a URL parameter (e.g., document.location = 'input.asp?dis=F';), catch that in the input.asp page and use the BODY tag's onload event to UNDISABLE certain form elements if the URL parameter value was F.

Anyone else?
