repeat you can create repetative behavior, that often will shorten the code a lot, if done correctly.
Its basic format is this:
repeat 10 times say "Hello." end repeat
And it can be used to do a specific task for every item you drop into a script that has been turned into a program.
on open (ListItem) repeat with thisItem in ListItem -- bunch of kick*** code end repeat end open
One example of actual script that utilizes repeat-function can be found here.
While, here is one example of code that will wait until a page in Safari is fully loaded:
tell application "Safari" to activate -- Brings Safari frontmost application. repeat tell application "Safari" if source of document in window frontmost contains "</html>" then tell application "Script Editor" to activate exit repeat -- This will quit the loop. else delay 1 -- Will wait for 1 second. end if end tell end repeat
