Hi there, I have a page in which I need to detect which element has the
focus.
The JQuery documentation states that the
http://jquery.com/docs/Base/Expression/CSS/ :focus selector is not
supported, so this would not be possible:
$("DIV INPUT:focus")
It is easy enough to add a selector def
Thanks Mike, that answers one question.
So a new :focus selector can be added like this: (for IE only so far. Boo!)
jQuery.extend(jQuery.expr[':'], {
focus: "a==document.activeElement"
});
// Example of usage: $("INPUT:focus")
Does anyone have an answer
These may give you some ideas...
You can either use JQuery's own .fadeIn() method or try the highlightFade as
follows:
$("INPUT")
.focus(function(){
$(this)
.highlightFade({start:'white', end:'black',
speed:'fast', attr:'color'})
Hello Mark,
Nice to see this bug progressing. A search on keywords "
http://www.nabble.com/forum/Search.jtp?forum=15494&local=y&query=classname+space
classname space " in the Nabble jquery forum reveals that quite a few of us
have reported this in one form or another.
Cheers,

It would seem that the fadeTo() method changes the element.style.display to
'block'.
Is this by design? It messes up inline elements.
One workaround for the time being might be to wrap an inline element inside
another before fading it.

Great info on ajax and forms. Is there any documentation on the forms plugin?

Good point about using $("../",this) as an alternative to using
$(this).parent(), though I've noticed that the syntax should be $("..",this)
to return the parent, while $("../",this) returns siblings. Does this sound
right?

Hi Mike,
You just need to tweak the JQuery syntax a little to refer to 'this' instead
of e.target:
Change from:

$(e.target).parent().next().slideDown('fast');
}, function(e) {
$(e.target).parent().next().slideUp('fast');
});

Yep, XPath will take you up the dom and down again but you'll still need to
use a method to get to the next row.
An advantage of Blair's example is that by using .parents() we do not have
to know how deep 'this' is within the TR. If the link is definately a child
of the TD then you could use som

Saw you had no responses so here's a couple of suggestions...
An easy performance booster is to use the second param in $() to set a
context for the search. Eg: $("DIV.myClass", myParentElement). Perhaps this
is what you meant when you mentioned 'getting a parent element' ?

If you have a jquery array of elements and need to call the show("slow")
method on each one in turn, how should you do it?
For instance how might would you reveal each LI element in a list one after
the other?
Just applying the show() method reveals them all at once eg: $("#myList
LI").show("slow
Thanks Jörn, good idea, that did the trick.
With some fiddling I was able to reduce the code to look like this, so it
can be applied to any list of elements:
var showInSequence = function($el){
if($el && $el.is())
$el.eq(0).show("slow", function(){
Very handy, thanks Choan.
By the way the little code rewrite I posted uses .next() because it assumes
the elements are siblings (which was ok for my purposes).
Jorn's technique, which you also use in your code, does not have this
restriction so it is better.
