[vrkamalakar]

Hi,

I got 3 text boxes and my requirement is once in enter 3 digits in the first text box, the focus should move to second text box and once i enter 2 digits in that then the focus should move to third text box. Iam using struts <html:text>. Can anyone help with a piece of code.

Regards,

You need to use an onkeyup handler which checks the length of the input on each key press. Also, set a maxlength for each text box so that the user does not exceed that. When the max length is reached, the focus can move to the next text box. W3Schools has an example which is almost exactly what you require. Adapt to your needs.
