Oops. got the selector wrong. It should be:
$( function() {
$(div[class^=hide-BAT].hide();
});
Joe
You still didn't get it right :-)
$(div[class^=Hide-BAT]).hide();
To original poster:
if you want fast, then you can't beat CSS with jQuery's hide method
have like:
div class=Hide BAT1
div class=Hide BAT1
.
div class=Hide BAT55
and now the CSS class Hide is defined like so:
.Hide { display: none; }
But, I'd suggest really reading into some replies above, you shouldn't
be using class names this way. if your div needs to be uniquely
identified, then ID is the way to go, and the class name BAT would
be used to grab all those uniquely identified div's
so building on that (note: id's are not supposed to start with
numbers, hence the B):
div id=B1 class=Hide
div id=B2 class=Hide
.
div id=B55 class=Hide
so now on page load, it'll see:
.Hide { display: none; }
and not show all 55 div's
want to do something to item 35?
function Action(id) {
$(#B + id).doSomething
}
Action(35)
want to do something to all 55 items?
$(.Hide).show()
doesn't that seem easier plus more importantly make more sense?
something like the suggested selector against your current structure
$(div[class^=hide-BAT]).hide();
while it *would work*, you need to understand why it is slow...
- first jQuery walks across the whole entire DOM tree grabbing every
single div, and that's whether it's one you are after or not
- then id needs to get every single class name, and do a (relatively
to other methods anyways) slow end with operator
Yuck and just think if you had 200 of those div's, or 400 !

I haven't tested this, but it should work. If not, verify the selector.
Not sure why you are giving a unique classname to all these elements. If
you need it, why not use the I'd attribute?

Hello,
Could you help me please. I have a list of hotel which I .hide
and .show div's to show more or less info.
so i have
div class=Hide-BAT1 ...
to
div class=Hide-Bat55 …
when the user press a button I use the code
var Hcode = $(this).attr(custom);
$('div.Hide-' + Hcode).toggle();
but when the page loads how do I hide this div automatically ?
I have used
for (i = 0; i = 70; i++)
{
$(div.Hide-BAT + i).hide();
}
But its slow and probably not the best way to do it ?
Hope you can help and this makes sense.
Regards
David
