Re: [jQuery] question on how not() works
Thank you for your help~~
And yes, I'm going to match a set of checkboxes with same id prefix.
(some multiple editable row control)

Also, just using = should be sufficient. If you're trying to match a
set of checkboxs, you should go against the @type attribute, or its
classname, instead.

Re: [jQuery] question on how not() works
.not() is really greedy, if filters out /everything/ that you specify,
so when you say:
[EMAIL PROTECTED]@name=checkbox]
You're saying:
- Anything that's not an input element
- AND anything that's type property isn't checkbox
- AND anything that's name isn't checkbox
It's the first one that's goofing you up, in the end you can probably
just reduce it to:
.not([EMAIL PROTECTED])
Hope this helps!

Hi all,
I'm a newbie in jQuery. I have some question on how 'not()' works. e.g.
HTML:
table id=test
tr
td
input type=checkbox name=checkbox/
input type=hidden name=hidden/
/td
td
input type=text name=text/
/td
td
select name=select name=select
option value=00/option
/select
/td
td
textarea rows=3 cols=11
name=textarea/textarea
/td
/tr
/table
JS:
$(document).ready(function(){
$(#test)
.find(tr).find(input,select,textarea)
.not([EMAIL PROTECTED]@name=checkbox])
.each(function(){
alert(this.name);
});
});
What I thought was that it should find all the input,select,textara in
tr ,remove all checkbox elements and alert their names. So I'm
expecting 'hidden','text','select' and 'textarea' would be alerted.
But in reality, it will only alert 'select' and 'textarea'. Why is that??

Re: [jQuery] question on how not() works
So, it's a special case in not()? Just to clarify:
If I use $('[EMAIL PROTECTED]@name=checkbox]') ,
It should read: select an input element with checkbox type and named 'checkbox'.
But in not('[EMAIL PROTECTED]@name=checkbox]') ,
It should read: select input element OR element with checkbox type OR
element named 'checkbox'.
Is that right?

.not() is the inverse of .filter()
.filter([EMAIL PROTECTED]@name=checkbox]') would be:
Is an input element AND is a checkbox AND is named checkbox
whereas .not([EMAIL PROTECTED]@name=checkbox]') is:
Is NOT an input element AND is NOT a checkbox AND is NOT named checkbox
I guess it's not the true inverse, but you get the idea.
