Event to detect when the text in an <input> is scrolled?

There is no specific event for this that will work across browsers. Firefox does fire a scroll event when the text "scrolls" by changing the insertion point, but Chrome and likely other browsers don't.

Here is a list of events that could change the insertion point.

• input
• keydown
• keyup
• focus
• blur
• click
• change
• paste
• cut
• scroll
• wheel
• dragover

Binding an event listener to all of these should be enough to respond to the insertion point changing. I believe the list above is complete, but if I have missed any, let me know!

Have you tried the Caret Plugin?

You can get the position of the caret with:

pos = $(textarea).caret()

and catch when it changes again. If the latter is different than the first then you know the user has moved inside the input.
