How to pass variables value from Applescript to Javascript?

I want to use “do script” in my applescript, but I need javascript to accept the variables which are being processed by applescript. It will prompt me error as the variables value from applescript is not being passed to javascript.

I search through the Board but found no solution on this issue. Hope someone can help me to solve this problem.

Thanks!

Your JavaScript is nothing more than a string of text so you should just be able to concatenate the parts together just remember that JavaScript is Zero based so you need to -1 for object values and object counts.
This should give you the basic idea.

tell application "Adobe Acrobat 7.0 Professional"
	activate
	tell active doc
		-- Get a variable from AppleScript
		set Page_Count to count of pages
		-- Concatenate into the JavaScript string
		do script "app.alert( 'This PDF has " & Page_Count & " pages.' );"
	end tell
end tell

What application are you scripting?

Some Adobe applications seem to support a with arguments option. You might try passing your arguments that way (they become available on the JavaScript side in a special array called arguments).

set jsCode to "frob( arguments[0], arguments[1] )"
tell application "Whatever"
	do script jsCode with arguments {"A", 3} -- on the JS side, arguments[0] == "A" and arguments[1] == 3
end tell

Great! Thanks, Mark67!

I think what I have confused is the usage of quotes (both ’ & "). I did try something similar before but received an error because I have added in extra quotes as below (after “This PDF has” and before “pages…”:-

I will try to figure them out later. Thanks again!

Is that with arguments something specific for Adobe or does it work generally?

It’s specific, as is the do script method. Eg, Safari’s do Javascript and Chrome‘s execute take a single string containing the script. Which makes a lot more sense.
