Dear devs, I propose we bundle the "validation as you type" livevalidation.js library [1] in XWiki, and use it to improve user experience on several forms in XWiki Enterprise (I can think of registration form, export wiki form, page creation panel, etc.) There are several advantages I see in livevalidation compared to the other libraries I took a glance at :
* It's small (12Kb minified) * It does not have any dependency (but there is version based on prototype available, too) * It is not intrusive. No need to modify the html structure or to add css classes to input fields to add validation. * It has an nice feature which allows you to precise the delay after which the validation should occur once the user stopped typing If you want to see it "live" in XWiki, I added some basic presence, password confirm and email validation on the register form on http://incubator.myxwiki.org CSS-class based validation seems to be in some sort of fashion, though I'm personally not very convince we can express all our validation using only class names (sounds intricate to do cross-field validation for example, or to validate against a custom regular expression), and for us it is not really an option right now, since we would need to make modifications in the core of XWiki for object fields displayer to add the proper class names to the inputs when calling APIs like $doc.display (or do it in javascript, but the CSS-based becomes pointless then). Last, if we really want class based validation, I believe building it with prototype and livevalidation would be very easy. Here are the other alternative I looked at rapidly: * JS-Validate [2] 67 Kb, requires prototype + scriptaculous, CSS-based , licence? * really-easy-field-validation [3] requires prototype, CSS + JS based, MIT licence * wForms [4] 81Kb minified, CSS-based , LGPL Better alternatives you would see? Otherwise, my +1 for livevalidation, Regards, Jerome.
