Thanks, Joel--
Thanks for the suggestion.
I tried your code suggestion in several tests. The "log" command was executed
only once each time, suggesting that the "delay" command was never executed.
Then I tried rearranging so that the delay came before the log: still only one
log command per test.
I tried Quitting Safari so as to take much longer. Still only one log command
appeared, but the page never appeared. Evidently "open location" creates an
invisible window, so I added an "activate".
This, plus the delay that you suggested to update the status, seems to have
done the trick.
Here's what worked:
set SecondsToWait to 30 -- Number of seconds to wait on Safari
tell application "Safari"
quit --set up for the test
delay 3 -- wait until almost certainly quiescent for the test
activate
open location "https://www.disney.com"; --begin test
repeat SecondsToWait * 2 times
delay 0.5 -- Add a small delay for Safari to update its status
set ReadyState to do JavaScript "document.readyState" in
document 1
log "ReadyState=" & ReadyState
if ReadyState is "complete" then exit repeat
end repeat
end tell
(*ReadyState=loading*)
(*ReadyState=interactive*)
(*ReadyState=interactive*)
(*ReadyState=complete*)
Much better than adding ad hoc delays to my code.
Thanks for the suggestion, Joel!
