JavaScript input mask/validator

Hi,

I'm looking for a good, clean as possible, javascript implementation
for form input masked input and/or validation.

I can search for it on the web, but there are tons of implementations,
mostly for aspx and other very heavyweight.

¿Does anybody recommend one that fits the "Seaside-way"?

Best regards,

validation could be done with scriptaculous and/or magritte + CSS I think...
For masks, I don't really see. It's about cancelling the last keyboard
entry if not compatible with the format provided ?

I found that for numerical masks. The script is not too long and
shoulnd't be too difficult to integrate
(http://javascript.internet.com/forms/dfilter.html).

For a phone number:
<td><input value="" type="text" onKeyDown="javascript:return dFilter
(event.keyCode, this, '(###) ###-####');">

Validation could work that way, but masking input not.
Validation could be done "per field" and masking must be done by char/keystroke.

The model will validate the field, but for some kind of users, having
a predefined input "shape" is better than having an empty text entry.
As sooner the feedback, less time is lost, and the user can do more stuff.

No, it can get more complicated if you have to deal with different
decimal separators, or a fixed size of decimal places, an ISBN code,
or any other arbitrary input.

I'm not speaking in the air, by now I only need a float input
validator, char-by-char if possible, if not, I can make my own with JS
and RegEx, but I'm looking for something more comprehensive.

uhm this one seems pretty cool
(http://javascript.internet.com/forms/input-mask.html), based on
prototype and just need a css class when rendered so as to have:
<td>Phone number:</td>
<td><input id="input_phone" type="text" class="text input_mask mask_phone"></td>

you then have to implement your filter in js... not very smalltakish
until some port was done


...

   /* Each mask has a format and regex property.  The format consists
    * of spaces and non-spaces.  A space is a placeholder for a value the user
    * enters.  A non-space is a literal character that gets copied to that
    * position in the value.  The regex is used to validate each character, one
    * at a time (it is not applied against the entire value in the form field,
    * just the characters the user enters).
    *
    * The way you name your masks is significant.  If you create a mask called
    * date_us, you cause it to be applied to a form field by a) adding the
    * input_mask class to that form field, which triggers this script to treat
    * it specially, and b) adding the class mask_date_us to the form field,
    * which causes this script to apply the date_us mask to it.
    */
   masks: {
      date_iso: {
         format: '    -  -  ',
         regex:  /\d/
....

I've found this before asking here, but I didn't like it, at least not
with confidence.

The best toolkit I've found so far is the www.zapatec.com toolkit, but
it's a full featured pack, and I can't use it as minimal as possible.

Best regards,

Hi,

Just for the record, I've found a JS Prototype based form validator,
its code is clean, and seems to work fast,
<http://www.tetlaw.id.au/view/javascript/really-easy-field-validation>.

The website even has some useful, and handy javascripts, such as the
FastInit.js <http://www.tetlaw.id.au/view/javascript/fastinit>.

I'll give both a try.

Best regards,

Also can you explain why ? because of ie incompatibility ? not enough
robust... It's relying on prototype like really-easy-field-validation
you showed us...

Thanks

I looked at it and didn't get the "I must use this" feeling.

Have you seen the page comments?
