I'd like to format a DecimalBox as I type the numbers. I know there is the onChanging event where I could do that, but I'm a little bit lost thinking of how could I write something like that.

A friend of mine wrote a piece of code which applies some mask to a textbox by using the onKeyUp event, but it is a local feature and it would be necessary include it every time I'd need to apply this mask. That's the fiddle: http://zkfiddle.org/sample/144bqmi/1-Another-new-ZK-fiddle

Is there a way to write a code like that and invoke it like <textbox onChanging="myscript">?

onChanging is a server side event listener, and your scenario sounds like it's better dealt with at client side to provide a better user experience. So here a few thoughts on improving the maintainability of your js code, avoiding duplication:

Inside a client side listener it is possible to call functions from separate js files which makes the function reusable in a very basic way. http://zkfiddle.org/sample/144bqmi/2-separate-mask-function

If you don't like functions polluting the global namespace you can add a custom maskInput function directly to the zul.inp.Textbox.prototype as in this example http://zkfiddle.org/sample/144bqmi/3-add-mask-function-to-textbox-widget

If you want to go deeper into client side customization e.g. extending an existing widget class with your own implementation I'd refer to the client side reference: https://www.zkoss.org/wiki/ZKClient-sideReference/GeneralControl/WidgetCustomization

For your case I think either my first or second option should provide a manageable mechanism.

Please let me know if this information was sufficient or not.

Yes, I was looking for something like this. Could I put a script on zk.xml and then invoke a function? I'm pretty sure I've read something about but I don't remember where it was.
