I was initially very attracted to jQuery because I am much more familiar with CSS syntax than JavaScript/ECMAScript. However, using it does not make me a better scripter, while YUI simply gives me cross-browser routines where I need them, so I can make better choices of technique as I learn the language. Protoype etc. I have yet to learn, but I understand the same thing is true.

Re: [WSG] Jquery and/or Yahoo UI
You're right; innerHTML is much, much, MUCH faster to execute (see http:// www.quirksmode.org/dom/innerhtml.html for numbers). It's also quicker to code and to implement. However it leaves you with less handles on the elements you're inserting, and 'feels' wrong (in the same way that sometimes a big table is the easiest way to centre content, but doesn't feel right), standards-wise. I'm a big fan of JS libraries. I use Prototype (and Script.aculo.us) and YUI quite a lot as the basis of a lot of my larger JS-based sites. The advantage of YUI isn't so much its ability to maintain strong standards, but its very strong cross-browser compatibility (so if you use Yahoo.DOM, you're getting a standard DOM across every browser; as with events, etc.). Prototype's biggest strength is its ability to keep common functions short and simple in your own code files. I can perform complex AJAX throughout a webapp with maybe three lines of JS (plenty of PHP, mind you). I've never really tried jQuery, because it's been marketed wrong for me. I've been using Javascript since ~1998 and have been doing things with it the "old" way (when everyone declared their variables on a global scope and functions were all called on the onclick, onmouseover events explicitly in code, and when anything fancy was called DHTML). I've spent the years since then developing my syntax and thinking to keep in line with the industry, and am comfortable with the syntax people have come to associate with "new" Javascript (Object notation, DOM manipulation, etc.). jQuery is marketed as a way to change JS syntax significantly (with a view to greater speed, marketed as a sort of Rails on the client side), which would mean a massive change for someone who already has four different programming/ scripting languages to flick between on a daily basis (not counting HTML and CSS syntax). I've heard only good things from people starting out with JS though.

(I might well be talking out of my backside here in which case, feel free to shoot me down in flames...) IIRC the innerHTML methods are significantly faster than W3C DOM methods in current mainstream browsers. In most cases it won't make a lot of difference, but if you're pushing a large amount of data around the page, it can be very helpful. I'm not saying you should use innerHTML exclusively -- In most cases I still turn to W3C DOM methods. Sometimes though, IE will slow right down, and innerHTML can be a good way of extracting a bit more speed from it. -- Olly http://thinkdrastic.net/ *** List Guidelines: http://webstandardsgroup.org/mail/guidelines.cfm Unsubscribe: http://webstandardsgroup.org/join/unsubscribe.cfm Help: [EMAIL PROTECTED] ***

When you fill the content of an element with innerHTML, the browser will render it but as far as I can remember, the content doesn't really exist properly within the DOM. The proper DOM methods, such as append, remove, etc. do build up the DOM properly. In a way, it's kind of like vs. . Of course, if you really want to use innerHTML, you could probably go right ahead.

Can you comment on Ext JS ? http://extjs.com/ I'd been wanting to know how it measure up with standards but thought this is not a place to ask, but where is the better place to get a better answer regarding standards? :) tee On Oct 12, 2007, at 10:56 AM, Christian Montoya wrote: On 10/12/07, Simon Cockayne <[EMAIL PROTECTED]> wrote: Hi, Anyone using jQuery (http://jquery.com/) or Yahoo UI (http://developer.yahoo.com/yui/) ? *** List Guidelines: http://webstandardsgroup.org/mail/guidelines.cfm Unsubscribe: http://webstandardsgroup.org/join/unsubscribe.cfm Help: [EMAIL PROTECTED] ***

If you want to absolutely follow standards, make sure you don't use any methods that wrap "innerHTML." jQuery has one but it also has a bunch of methods that use the proper DOM methods (appendElement, removeElement, etc) so stick to the proper DOM methods and you will be fine. -- -- Christian Montoya christianmontoya.net *** List Guidelines: http://webstandardsgroup.org/mail/guidelines.cfm Unsubscribe: http://webstandardsgroup.org/join/unsubscribe.cfm Help: [EMAIL PROTECTED] ***

YUI is much more then a Javascript library, and it outputting alot of HTML and CSS could (possibly!) make it break your valid pages. I am using YUI, its very nice, but i've only been using it for some small things and I did not yet validate them, and even if I had, it would not be a guarantee for other parts of the library. It *is* tested in alot of browsers for compatibility, which is maybe even more important then standards compliance (sorry...). regards, Maarten > > If you consider WCAG a "web standard", then you need to make sure that > your > page "is still accessible when scripts are turned off" (or words to that > effect).
