I am looking for some way to control the pasting in my web based
application.
The reason I would like to control pasting is because the application
includes a table that looks like a datasheet. If the user copies 10
rows from a spreadsheet and clicks on the textbox and pastes it, I
would like to get the data in a back-end process and insert them into
the database and then display the table with the new rows added.
In other words, if the paste is a single value, then I want to let the
paste go through. If the paste is more then that, then I would like to
process it and not let the paste go through. In order to do this I need
the data from the clipboard accessible and I need the paste to not go
through.
I know there is no OnPaste event in firefox, I was wondering if anyone
knew of a work-around.
thanks

Wouldn't that be, like, a huge security issue?

1) No that would not be a huge security issue if implemented correctly.
What might be a minor security issue is if the browser has constant
access to the clipboard and could then on a timer copy your clipboard
and send it to another host. However, controlling the onpaste, which is
only onpaste into the browser not onpaste on the system. Means that the
data you are pasting in is accessible to the web browser immediately
after the paste and it can do with the data what it would like.
2) If all Internet security issues were kept out of the browser then it
would be next to impossible to write an Intranet application that does
not need to worry about outside security.
