I have the following problem and was wondering if I could do this with JSP.
Basically I have a form with which I enter data into a database. In the form are textfields. One of the textfields is for numbers only. Upon entering numbers within the textfield I want it to change its background colour. For example: If its below 8 digits the bgcolour is yellow , if its exactly 8 its green and if its over 8 its red.
Is it possible to do this with JSP ? If yes , how ?
