[jQuery] Re: test for .is(:visible) fails in Safari
Ricardo,
Thanks so much for responding. That's very helpful. My use of events has
been very rudimentary so far; your .bind() example has helped me
understand them more fully. And now that I know what I'm looking for,
various approaches to the problem have been illuminating as well.
for example ajp's recent thread::

[jQuery] Re: test for .is(:visible) fails in Safari
Dear all,
OK, solved it myself in case anyone's still listening. It still remains a
puzzle why safari on Mac interprets the code differently.
The if/else test below isn't necessary. The fadeOut was executing, but the
.load() callback failed when the .thumb clicked was the same one as the
previous click. Both FF and IE didn't blink when the src of #pic remained
the same, but safari wouldn't execute the .load callback because nothing
loaded: the src of #pic remained the same.
The solution for my purposes was to set the src of #pic to null and then
re-set it to pix[imgName].imgSrc whatever it might be, then .load() sees
that something has loaded and executes the callback.
Is this a known discrepancy between how FF, IE, and Safari interpret
.load(), or something completely screwy and idiosyncratic to my klugy
code? (jQuery 1.2.6, by the way, in safari 3.1.2)

In FF clicking on the same image twice makes no change, but in Safari,
clicking on the same image twice makes no change IF #dropdown is visible, if

[jQuery] Re: test for css selector capability?
Hi, I realize that jQuery.browser is now deprecated, but I'd like to give a use case where it makes sense to use jQuery.browser: I have some code where each browser renders slightly differently, such as how they treat borders for DIVs. If I use jQuery.browser, I can update the CSS appropriately for the quirky browsers. If jQuery.browser is eliminated in the future, I still need to detect rendering quirks. This isn't about whether a browser supports a particular CSS or JavaScript feature, but instead it involves subtle but important differences in the rendering engines for the four major browsers: WebKit (Safari/Chrome), Gecko (Firefox), Trident (IE) and Presto (Opera).

[jQuery] Re: test for css selector capability?
You could do this because the .css(attribute) returns the computed
(the result of all the CSS applied) value of an element's CSS
attribute.
It would involve adding a stylesheet to the document with the
particular selector in it, with say a change to the background colour.
Then create elements that should be selected (and add them to the
document), then test the .css('background-color') of the element to
see if it matches the colour in the stylesheet.
Slightly tricky but doable.

[jQuery] Re: Test if a variable is a jQuery object?
This sort of thing can happen a lot if you're writing functions which
take multiple inputs, based on convenience. Being in control of your
code shouldn't be a fascist thing like you're describing, where
there's only one way in which everything can or should happen. Having
openness in parameters is always a good thing.
And with that, you'll want to use instanceof to solve the problem.
var someObj = document.getElementById('div1'), otherObj = $('div
id=div2/div'), thirdObj = {};
if (someObj instanceof jQuery); // false
if (otherObj instanceof jQuery); // true
if (thirdObj instanceof jQuery); // false
Whereas all options return object in a typeof check, instanceof
allows you to compare an object with an instantiation object, like
jQuery.

My code passes in a pure jQ object, whereas the jQuery code passes in a

[jQuery] Re: Test if a variable is a jQuery object?
There're different ways:
obj instanceof jQuery
obj obj.constructor == jQuery
obj obj.jquery
And any other possible attribute sniffing, 'jquery' is obviously the
safest.

This sort of thing can happen a lot if you're writing functions which
take multiple inputs, based on convenience. Being in control of your
code shouldn't be a fascist thing like you're describing, where
there's only one way in which everything can or should happen. Having
openness in parameters is always a good thing.
And with that, you'll want to use instanceof to solve the problem.
var someObj = document.getElementById('div1'), otherObj = $('div
id=div2/div'), thirdObj = {};
if (someObj instanceof jQuery); // false
if (otherObj instanceof jQuery); // true
if (thirdObj instanceof jQuery); // false
Whereas all options return object in a typeof check, instanceof
allows you to compare an object with an instantiation object, like
jQuery.

I just did something similar to your sollution but ended up in the
same problem (duplicating the error-message). Did you already found
the sollution to it?!

Here's what the docs say about the groups option:
A group consists of an arbitrary group name as the key and a space
separated list of element names as the value.
I guess I'm looking for a more general and expandable way to do
this...

[jQuery] Re: Test if jquery has loaded
It's not a case of the alert not showing up. That would result in an
error halting all processing. So for a human sitting at the screen that
would give us the data he wanted. But for code that needs to do
something differently if jQuery were not loaded, the alert method would
just fail and the alternate code would never fire.
Of course, it comes down to what the coder really wants. He/she now has
two options.

That's not quite right. .filter() returns a jQuery object, which will
always evaluate to true. To use it your way, you'd want to do
if($(this).filter(.selected).length) which will return 0 if there are
no elements, or a positive integer if there are.
Michael was correct in his example of $(this).is(.classname), which
will return a boolean value as required.

A function is just a variable.
if( !!modify ) alert(exists);
if( typeof modify == function ) alert(exists and is a function);
These are just a few methods of testing.
Safest way to test for global variables is this:
if ( window.myVariableToTestFor ) {
// its there!
}
I've experienced quite a lot cases where checking for a global variable
that didn't exists without specifying window as the property's object
threw ugly errors.
