javascript pseudo-protocol HREF is harmful

odd problem about innerHTML & img under IE - comp.lang.javascript | Google 網上論壇

Executing a javascript pseudo-protocol HREF in IE browsers (at least up
to 6) convinces the browser that it about to navigate away from the
current page (as would be the normal consequence of following the HREF
of a link) and puts the browser into a 'waiting' stat in witch various
facilities stop working (or working in the previously expected way). One
of the more often observed symptoms is the browser failing to
load/display new images. This is usually reported as the unexpected
stopping of image swapping with rollovers, but any failure in an image
related operation after the execution of a javascript pseudo-protocol
HREF might be attributed to this.

It comes down to this: when you use this in for instance an href-attribute you are most probably misusing an anchor-element for something that is not related to navigation. "You should not use a link for anything else but a link" - it's the basis of the web: links are for navigation and not for in-page behavior*. Got that?

Note the 'return false': this prevents a JS-capable client to actually start navigating to 'alternative.html'. That brings us to another problem with the javascript: pseudo-protocol, namely the fact that IE (at least up to version 6) enters a different 'state' when the href of a link is being followed no matter if it contains an actual link or a javascript function. This is most noticable when you have animated gifs on your page: when such a link is clicked they stop animating, and there are probably more problems that can arise from this 'state'-change in Internet Explorer. Wrapping your function-call in the void() operator doesn't change that either.

Re: A tag: href vs. onClick
update: 可以用< a id="next" href="#">

YUE.on('next', 'click', function(e){
    doSomething(); 
    YUE.stopEvent(e); 
    return fasle
})
