Interacting with the Browser widget

I am interested in copying text from a web site through the Browser widget. Any possibilities?
e.g. select a text, then have a script copy that text and use it in a handler. Is that possible?

[Repost because my first answer was partially wrong].
[Edit: If you use it with ordinary mouseDown or mouseUp the widget may loose focus (and the current text selection, especially in Safari-like browsers)]
Code: Select all
-- copies current text selection from a webpage displayed in the browser widget
on mouseDown b
if b=3 then
do "document.execCommand('copy');" in widget "browser"
put the fullClipboardData["text"] into txt
answer "Copied:" &cr &txt -- do something with txt
end if
end mouseDown
If you have full control over the page you can get the innerHTML of a DOM element, for example from a textarea or an input element of type"text".

Thanks for that. I have put this in a button, and I select text in the browser widget, but it is not copying that text. It uses what was in the clipboard before. Any ideas?

Use a method such that the widget doesn't loose focus: rightClick (or mouseEnter or ...).
Code: Select all
on mouseDown b
if b=3 then
do "document.execCommand('copy');" in widget "browser"
put the fullClipboardData["text"] into txt
answer "Copied:" &cr &txt -- do something with txt
end if
end mouseDown

Great. This is working now.
So it seems there are no handlers like mouseWithin etc that a browser widget understands, right?
Is there any way we can sense remotely that a text has been selected by user? Perhaps test each 1 second and if the focus of the browser is true and text is selected then grab the text?

Add an event handler to your webpage that calls back to LC.
Then you get without anything more needed always a "notification" from the webpage, as soon as the user has selected some text, attached the selected text.
This isn't difficult but not a 5 minute job.
(5 minutes is the limit to answer posts in the forum or the list I set for me in 2018.)
Given time I'll make a demo-stack with this (and more) in subforum HTML5/Browser widget usage examples.
