#urweb-ctextbox-echo

This is a very minimal Ur/Web example using a source and a signal to instantly echo the changes which the user makes in a <ctextbox>, in an <xml> fragment (created in a <dyn> tag) directly below the <ctextbox> itself.

Note:

I was somewhat surprised to discover that this example did not need to use an onkeyup event in the <ctextbox>.

I now understand that this is because the source updates the signal automatically, with no need for an onkeyup event.
