Input controls on-the-fly?

Rails
1

i wish to know if there is some way to check user-input directly while
it’s inserted.
for example if i have to insert a number and the user press letters i
just have to hide/delete the letters and wait for numbers.

all without the need to press some submit button or any link…just
automatically.

Thanks
Lepre

It’s called JavaScript. Do a Google search for JavaScript validation and
you’re bound to find what you’re looking for.

i know js but till now i only found validation after the submit button
(that’s why i said it) and nothing about on-the-fly…

i posted here also to know if there something directly in rails or not

I’m no rails guru so I couldn’t tell you if there’s something in rails
to do it automagically, but in JavaScript do something like -
