Call AppleScript on file change ?

Question

Hi,
is it possible somehow to start AppleScript when content of file change? (using FolderAction or whatever??)
I'm using textedit (Coda) for HTML and PHP coding and I want to Safari reload page every time when I save file (hit Command+S).
Q: is it possible to triger AppleScript when I save from some App or to detect that content of file is changed (due saving file from App)?
Thank you in advance!

'Is it possible somehow to start AppleScript when content of file change?' - no.
'using FolderAction ...' - no.
'... or whatever??' - depending on 'whatever', most likely - not.
'Q: is it possible to triger AppleScript when I save from some App or to detect that content of file is changed (due saving file from App)?' - no.
Possible solutions:
01. You can create an AppleScript applet (application) which constantly checks a known files' 'modification date', and act accordingly.
02. You could use an utility application such as 'Butler' and via its 'Smart Item, AppleScript, AppleScript'' feature - assign a keyboard equivalent for 'TextEdit', 'Coda', or another editor application to save the contents of the applications' frontmost document, and then tell 'Safari' to open (and thus - reload) a respective web page.
For example:
Within 'Butler' a 'Smart Item, AppleScript, AppleScript' was created, and assigned '<control> <shift> c'.
The associated starter Source Code is ...
-- Code starts here --
set tFile to (((path to desktop folder from user domain) as string) & "index.html")
tell application "TextEdit"
activate
save document 1
end tell
tell application "Safari"
activate
open (tFile as alias)
end tell
-- Code ends here --
Make sure to set 'Bulter's 'Triggers' tabs' 'Hot Key' 'Exceptions' popup button menu to 'Only'; add 'TextEdit', and / or what text editor(s) you use, to the textedit field beneath the just mentioned popup button; and actually assign a 'Hot Key' value - such as '<control> <shift> c'.
The code is brief, crude, and works.
You will have to refine the code so ...
set tFile to (((path to desktop folder from user domain) as string) & "index.html")
... can be removed, and whatever document is the front most of 'TextEdit', 'Coda', etc. is saved, and then opened by 'Safari'.
