Re: [jQuery] When to Use'.' When Referring To Css Classes In JQuery
Hi Mark, I checked my pre-release PDF of the book as well as a print copy and haven't been able to locate the code that has return $cell.find('sort- key') without the "." for the sort-key class. If you wouldn't mind, could you point me to the page number where you saw that? I'll make sure it gets into the list of errata on the Packt website and at http://book.learningjquery.com/6705/errata.html thanks so much, --Karl Karl Swedberg www.englishrules.com www.learningjquery.com On Nov 3, 2009, at 8:06 AM, Mark Phillips wrote: Hi, Is there some general rule to determine when '.' should be added to JQuery method parameters when referring to CSS classes.

How does one know when to include the '.' Thanks, Mark PS. I accidentally placed this in the JQuery Plugin Discussions. Apologies for the duplication.
Re: [jQuery] When to Use'.' When Referring To Css Classes In JQuery
"." should be used each time you're looking for a class using a search pattern. That's all. There may be a typo in the aforementionned excellent book.

[jQuery] When to Use'.' When Referring To Css Classes In JQuery
Hi, Is there some general rule to determine when '.' should be added to JQuery method parameters when referring to CSS classes. Here's an example from the excellent book "Learning JQuery 1.3" if ($header.is('.sort-alpha')) { findSortKey = function($cell) { return $cell.find('sort-key') .text().toUpperCase() + ' ' + $cell.text ().toUpperCase(); }; } In this case both '.sort-alpha' and 'sort-key' are CSS classes.
