Question

does anybody know how to turn a textfield to allow user inputs of numbers only using javascript? I know this can be googled but solutions are all the same ex: (http://www.htmlcodetutorial.com/forms/index_famsupp_158.html). What I want is to filter any inputs not only coming from the keyboard but also but also from the mouse like doing copy & paste non-numeric values on the field. Any help will be appreciated.

Answer 1

Use onChange:

 <INPUT NAME="dollar" SIZE=5 MAXLENGTH=5 onChange="this.value = this.value.replace(/[^0-9]/g, '')">

Note: In FF3 at least it only runs after the value has been “confirmed”, box lost focus or other and not instantaneously.
