If you use jQuery (like I do) you might not know that jQuery 1.4 was released last week (like I didn't).

Info here: http://jquery14.com/day-01

Bottom line: It's far faster.

I should probably stop using

Code:
$(function() {

});


now as a lazy way to initialise things, then. Pfft.

I haven't upgraded yet. It's nice to see there's a plugin to enable backwards compatibility, but I'd rather tweak my existing sites if anything does indeed break.

Never used it, but I need to start really using more JavaScript in our Intranet, so I might take the plunge. Seems to do stuff that I want the fancy new version of our site to do.

It's a lovely little library. Are you comfortable using CSS selectors?

I don't do anything very complicated with them at present.

Oh, no. That still works, apparently.

Reading through the changes, and there are lots of brilliant things in there. Plenty of stuff I can already see real applications for and ways to simplify my existing code. Excellent.

jQuery identifies page elements in the same way as CSS does.

For instance,
Code:
$(".footer").html(); //gets you all the HTML in your footer(s)
$("img").hide(); //hides all your images
$("#option_1").css({"color":"red"}); //changes your text to red if it's in something with the id 'option_1'

You can do all the complicated selectors too, like
Code:
$("div > span").something();
$("div[class~='x']").something();
$("div[id|='brian'").something();

Post subject:  Re: jQuery
It is very nice.
The spoiler tags use jQuery, and it's only a tiny bit of code:
Code:
$(".jqspoiler").click(function() {
    $(this).children(".hidey").slideToggle(200);
});

In pseodo, that basically says:
Find all the elements (divs, in this case) with the class '.jqspoiler' and run this function when someone clicks on them
Any elements (divs again) that lay inside the one that was just clicked on with the class '.hidey' should be slid upward and hidden if they are visible, and downward and shown if not. Spend 200 milliseconds doing the sliding.

Apply some CSS to make the .hidey divs hidden by default and that's it!

I'm finding this sort of thing to be especially useful for placating directors who insist that their "thing" should be in six inch high green flashing letters in the middle of our intranet home page. Seeing it "fly out" instead usually seems to make them pretty happy.

Two geeky programming threads on the front page, whatever next?

Anyway, why does
Code:
$(window).resize(function() {
    resizeWindows()
});
work, but not
Code:
$(window).resize(resizeWindows());
?

Post subject:  Re: jQuery
I don't know JS too well, but I'm guessing the first passes the reference to the function to your "resize" function, but the second calls resizeWindows and passes the result to resize.
Author:  BikNorton [ Wed Feb 23, 2011 17:18 ]

Wouldn't it be

That didn't work.
All I want it to do is fire the 'resizeWindows' function when the window is resized.

It's backward to what you said, but I think that's the case.

Post subject:  Re: jQuery
Hm. I thought like Squirt - the former sticks a function block in, but the latter doesn't. My experience of this sort of thing is nothing to do with jQuery, just that when making JS objects here people tend to do
Code:
Object.prototype.Function = Object_Function;

function Object_Function() { alert("Gah!"); }
whereas I prefer
Code:
Object.prototype.Function = function() { alert("Gah!"); }

One crash course in JS later, does

Code:
$(window).resize(resizeWindows);


as opposed to

Code:
$(window).resize(resizeWindows());


work?

That would be my suggestion. The callback in your $(window).resize() should take a function name (or anonymous function as in the working example) so leave out the parentheses. I think.

Should probably point out that jQuery 1.5 is out, too, but early reports suggest it isn't playing nice with ui, so I'm leaving it alone for now.
