Using Javascript to enter text fields

I’ve been trying to select text fields and change their value and then click a button using javascript in Safari, but I can’t seem to get the code right.

Can anyone give me some examples of what I need to do?


Hit the Search button (above) and enter “do AND JavaScript AND document” (you’ll find several examples using Safari)

cool, that got me what I needed…

I’ve got one more question (for the moment :rolleyes: )

Is there a way that I can set a variable to a particular piece of text on the web page, like I want to copy a number that occurs on the web page (the number changes, so I can’t do something like a find) but it is always in the same spot, and I want my script to be able to preform some math on it.

So how can I select that number and put it in to a variable so I can use it in the script?

Thanks agian

If you ask for the page’s properties formally…

tell application "Safari" to properties of document 1

You’ll see that you can retrieve both the “source” (html) and the “text” (displayed text).
So, you can:

tell application "Safari" to set theText to source of document 1

Now, the variable “theText” contains the following:


And you can get it as follow:

set theNumber to text ((offset of "<b>" in theText) + 3) thru ((offset of "</b>" in theText) - 1) of theText as number

But depending on the complexity of the text to search in, you can use different methods.

I’ve got a handler I use for this since I do this kind of thing a lot. You can send it a list, where the list is {sourceText, textBeforeDesiredText, textAfterDesiredText}. You can also send it a record if you want more control. The default behavior is to find the first occurrence of your search items. There are two samples shown below:

set someText to "Contact:Jeff Robertson" & return & "Phone:856-321-4567" & return & "Fax:856-321-9999"

getTextBetween({someText, ":", return})
--> "Jeff Robertson"

getTextBetween({sourceText:"Jeff is my friend", beforeText:"Jeff", afterText:"friend"})
--> " is my "

on getTextBetween(prefs)
	-- version 1.4, Daniel A. Shockley <>
	-- gets the text between specified occurrence of beforeText and afterText in sourceText
	-- the default textItemNum should be 2
	set defaultPrefs to {textItemNum:2}
	if (class of prefs is not list) and (class of prefs is not record) then
		error "getTextBetween FAILED: parameter should be a record or list. If it is multiple items, just make it into a list to upgrade to this handler." number 1024
	end if
	if class of prefs is list then
		if (count of prefs) is 4 then
			set textItemNum of defaultPrefs to item 4 of prefs
		end if
		set prefs to {sourceText:item 1 of prefs, beforeText:item 2 of prefs, afterText:item 3 of prefs}
	end if
	set prefs to prefs & defaultPrefs -- add on default preferences, if needed
	set sourceText to sourceText of prefs
	set beforeText to beforeText of prefs
	set afterText to afterText of prefs
	set textItemNum to textItemNum of prefs
		set oldDelims to AppleScript's text item delimiters
		set AppleScript's text item delimiters to the beforeText
		set the prefixRemoved to text item textItemNum of sourceText
		set AppleScript's text item delimiters to afterText
		set the finalResult to text item 1 of prefixRemoved
		set AppleScript's text item delimiters to oldDelims
	on error errMsg number errNum
		set AppleScript's text item delimiters to oldDelims
		-- 	tell me to log "Error in getTextBetween() : " & errMsg
		set the finalResult to "" -- return nothing if the surrounding text is not found
	end try
	return finalResult
end getTextBetween
