hi everybody, i have a form with validate functions... when i use the keyboard the validate fs work perfect, but if i use my mouse to paste some data in that text box the fs function doesn´t work... maybe i am putting the validate in the work event... or i have to use another function...
can anybody help me...
thanks in advance

You're probably using a "key" event on a textbox. Try firing your validation "onsubmit" on the form instead of "onkeyup" / "onkeydown" / "onkeypress" of individual text fields.

Of course, this assumes you don't want validation to happen "on-the-fly". If you do, the best you might get is to harness the "onblur" or "onchange" events of each field.

Hope this helps,

I think you should validate the form once it's submitted, but if you really want to change the pasting behavior of the browser IE supports the onbeforepaste and onpaste events which you could use to validate the clipboard contents before it gets inserted. I would guess that Firefox probably handles events similar to this as well.

Yes,
I used the onmousemove event of the form... with the isNaN(field), so i erase it if the value is not a number..
and the field onkeydown and onmouseout events...
although i didn't test it a 100%... thats something that i will do... fortunately i can wait a couple of days to put that validation on production...
