[jQuery] jQuery Selector Help
Long time listner, first time caller ...
I am struggling with a selctor and am hopeful someone can help me see
the forest through the trees. I am using a WordPress plugin which
generates the following HTML:
td class=day-with-date
span class=weekend26/span
span class=eventbr /
*
span class=calnk nowrap=nowrap
a href=# style=Christmas Break
span style=
div class=event-titleChristmas Break/div
div class=event-title-break/div/span/a/spanbr /
*
span class=calnk nowrap=nowrap
a href=http://localhost/?p=104; style=
Futsal Training
span style=
div class=event-titleFutsal Training/div
div class=event-title-break/divstrongTime:/strong 1:30
pmbr /
div class=event-content-break/div
Futsal Training at NetSports
/span
/a
/span
/span
/td
I want to strip the asterisk characters (*) from the HTML. I have
been able to tweak a few things but I am struggling with a selctor
which would allow me to eliminate the asterisk. Any help or
suggestions would be approeciated. I was trying to do this but
innerHTML returns undefined and I am not sure why.
jQuery('span.even br').each(function() {
html = this.innerHTML ;
// Some manipulation goes here
jQuery(this).html(html) ;
}
I am by no means a jQuery guru so I am sure I am missing something
obvious.
Thanks,

[jQuery] Re: jQuery Selector Help
Well, you selected BR elements, which are empty elements, so it's no mystery why this.innerHTML returns undefined... Also, DIVs shouldn't appear inside SPANs...

He did state that he's using generated HTML. He has no control over it.
Mike - this isn't really a jQuery problem per se. You're jQuery selectors
match DOM elements. Not so much the contents of those elements.
What you can do is search for the containing element (in this case, you can
look for a span with a class of event), and replace all instances of br
/* with just the br /.
$(document).ready(function() {
var newHTML = $('span.event').html().replace(/(br.*)\s*\*/g, '$1');
$('span.event').html(newHTML);
});
The expression is looking for a br / (or br or br/) followed by any
white space (including tabs), followed by an asterisk. It replaces that
pattern with the br / alone (removing the asterisk).
Disclaimer: I'm no regex guru, so if anyone sees a way to clean up that
expression, please feel free.

Thanks for pointing me in the right direction. This is what I ended
up getting to work:
jQuery(span.event, .calendar-table).each(function(){
var html = this.innerHTML.replace(/(br\s*\/*)\s*\*/
g, \'$1\');
jQuery(this).html(html) ;
}) ;
I changed the regular expression slightly to eliminate the .* portion
and changed .html() to .innerHTML. I don't know enough jQuery to know
why I had to do that but had seen it elsewhere so tried it and it
worked.

.html() retrieves the innerHTML.
Really no functional difference, but for the sake of consistency, since
you're leveraging jQuery, I'd prefer to see consistent jQuery code (unless
there's a compelling reason not to).
And yeah... just a preference. Not saying wrong or right. But I am saying
you shouldn't have -had- to do that :)
Anyway, glad you got it working. That's the important bit :)

Re: [jQuery] Selector Help
That's a nice solution.
Let's make it easier to follow with some indentation:
$('a.filter').click(function() {
$(this)
.closest('ul')
.children()
.removeClass('active')
.end()
.end()
.closest('li')
.addClass('active');
});
The basic indentation rules we're following here are:
* Put each method call on a line by itself, with the . at the beginning of
the line. (You can put more than one call on the same line, but only when
they don't change the selection.)
* Where a method creates the jQuery object or changes its element selection,
indent the next line.
* Where .end() is called, un-indent that line.
You could even go overboard on readability and add the missing .end() calls
at the very end:
$('a.filter').click(function() {
$(this)
.closest('ul')
.children()
.removeClass('active')
.end()
.end()
.closest('li')
.addClass('active')
.end()
.end();
});
Now this looks a lot like the way we indent blocks in JavaScript and other
languages. Each .closest() or .children() call is matched up with its own
.end() call - as is the initial $(this) - and the indentation indicates the
code affected by each of those calls.
It's more customary to omit those trailing.end() calls, but with or without
them, the indentation is a great help in visualizing the structure of a
complex chain.

I'm pretty new to Javascript/ jQuery, so this is really bugging me.
I'm trying to get the height of an h1 that is a sibling to this. The
value for the variable h1Height, however, returned as null in the
console in Firebug. Perplexed, I tried console.logging ('this'+'+h1')
to see what it was interpreted as. It brought back this+h1, which
should select an h1 adjacent to this (which is a div).
Javascript
h1Height = $('this'+'h1').height();
What went wrong?

$('#menulinks a').hover(function(){
setTimeout(function(){
$(this).stop().animate({
top : '40px',
paddingTop : '40px'
});
}, 1000);
});
});
Before I added a timeout, (this) sufficed. With the timeout set, (this) did
not select the hovered link. I tried another selector and it worked fine.
How can I specify (this) for this situation?

[jQuery] Selector help
I'm either making this more difficult than it is, or I'm missing something simple... I have a div that contains a table. Inside that table I have rows with an arbitrary number of cells. The cells may or may not contain a div with a tasksummary class. I need to find all the rows that DO NOT have a task summary div, and toggle them. I can easily find the tasksummaries: $(#containerDiv table tbody tr .tasksummary); But how do I change this to give me the TR's that don't have a task summary div? (note, some of the cells may contain sub tables, so the explicit tabletbodytr isolates only the main table...) The only method I can see right now is to find the TRs then do a .each() on them and check each row with the .hasClass(). But I'm sure there's an easier way... Thanks for any input. Shawn
[jQuery] Selector Help - hover and dblclick
In a table like this:
table id=choices-table border=1 width=75%
trthItem/th/tr
tr id=row-1tdOne/td/tr
tr id=row-2tdTwo/td/tr
tr id=row-3tdThree/td/tr
/table
I want to highlight the rows when hovered. I also wan't to set a
different background color on the row when double clicked. I have the
following jquery code:
$(document).ready(
function() {
$([EMAIL PROTECTED]'']).hover(
function(){ $(this).addClass('hilite'); },
function(){ $(this).removeClass(); });
$([EMAIL PROTECTED]'']).dblclick(function(){
$(this).removeClass();
$(this).addClass('dblclckd');
});
}
);
Note: in the above selectors that is @class=single quotesingle
quote
The hover is highlighting the rows. The double-click is changing the
row background. The problem is when if I hover over the previously
double clicked row. It loses its styling.
What I'd like to do is prevent the hover from acting on any row that
has been double clicked. I'm trying to do this based on the hovered
rows class, but that isn't working.
Ultimately, I'd also like to prevent the double clicked row from
running code if previously double clicked.
