IMO, it should be avoided to have a controlled input. As you already mentioned the problems. But even if I need to keep it --e.g.-- to numbers: A much more user friendly UI is to present the user with an error message (next to the input) stating exactly what's wrong with his/her input. The other typical example like "all capital" can easily be applied afterwards when sending the content to the server. I haven't tried this but it probably works: You can also just listen to "onkeypress" and just prevent the default (ie the browser populates .-value) and populate it yourself (filtered). This means that instead of losing input you'll just have a lagging UI. Better, but not optimal. This brakes down for copy and paste (and possibly other input?), so you'll still need to listen to on-change. Sometimes, I even lose keypresses with my fast PC since my computer is busy with other stuff. So the controlled input which relies on timing is a big no-no IMO. -- Note that posts from new members are moderated - please be patient with your first post. --- You received this message because you are subscribed to the Google Groups "ClojureScript" group.
