Does anybody know how to change an entered symbol seamlessly with javascript? Because when I just replace an already-printed symbol with the desired one (something like onkeyup="this.value=this.value.replace(/,/g,'.')"), the user sees the replacement occur: you press comma, comma is printed, then it's replaced by a dot. Of course, it happens quickly so it's not a big problem, but anyway I want the dot to be printed immediately without printing and replacing the comma first. Is it possible?

You will have to cancel default event and add the other character to the input manually

Look at this question it should help you: how to insert dot instead of comma in js keypress

Try using onkeydown instead and stop the event from propagating.

A quick fiddle I did to try this out ... this is quick and dirty and may cause issues.

  • Use the technique referenced by Jan Pfeifer. It is much more robust than the q&d I did above. – Dave G Oct 07 '11 at 13:01

Yes , You have to use javascript event like
1) onkeydown
2) onkeyup
to achieve your task. So first try yourself .
If you have further problem then you can ask..But First TRY yourself.
