Therefore, Applescript is ideal for automating Safari to do it
right. However, the problem is knowing when the HTML is ready for
capture, without waiting forever++
I offer you guys the following code, which works MOST of the time
(eg. a frames problem that Gary clarified on another posting.)
Questions:
Why should it have to be this damn complicated?
Any ideas for doing it better?
Doesn't this do about the same thing, John?
----------
to getHTML from myURL
tell application "Safari" to tell document 1
set URL to myURL
repeat 40 times
if URL is myURL then return source
delay 0.5
end repeat
end tell
error "Oops - problem accessing internet..."
end GetHTML
getHTML from "http://www.apple.com/";
----------
----------------------------------------------------------------------
----------
on run
GetHTMLfromWebsite("http://www.apple.com";)
end run
----------------------------------------------------------------------
----------
on GetHTMLfromWebsite(myURL)
tell application "Safari"
set URL of document 1 to myURL
if my WindowLoadProblem(id of window 1) then error "Oops -
problem accessing internet..."
return source of document 1
end tell
end GetHTMLfromWebsite
----------------------------------------------------------------------
----------
on WindowLoadProblem(winID)
--------------------------------------------
-- Step #1: Window name change signals the start of a load.
-- Note: WINDOW name is testable, but DOCUMENT name is not!
--------------------------------------------
tell application "Safari"
set the name of window id winID to "Waiting to Start!!!"
set thisName to "Untitled"
repeat until thisName does not contain "Waiting to Start!!!"
delay 0.5
set thisName to name of window id winID
end repeat
end tell
--------------------------------------------
-- Step #2: Javascript "readyState" signals the completion
-- Problem: apparently, use of HTML frames may set readyState
prematurely!
--------------------------------------------
set pagefailed to true
set n to 0
repeat until (not pagefailed) or (n = 40)
delay 0.5 -- seconds delay between tries, with a timeout
after 40 tries
set n to n + 1
tell application "Safari" to set r to ¬
(do JavaScript "document.readyState" in document 1 of
window id winID)
if r = "complete" then
set pagefailed to false
end if
end repeat
return pagefailed
end WindowLoadProblem
