The previous responses don't seem to get that you're using the metadata plugin. I would suggest using filter:
$('tr').filter(function() { return $(this).metadata().id == 4; })... If you find yourself doing that a lot, you can add a custom selector for metadata. Something like: jQuery.extend(jQuery.expr[':'], { meta: "!m[3]||((p=m[3].split('='))&&(p.length>1?$(a).metadata()[p[0]]==p[1]:$(a).metadata()[p[0]]))" }); Which you could then use like: $('tr:meta(id=4)')... I put together a little test page: http://erikandcolleen.com/erik/projects/jquery/metaselector/ Seems to work in IE7 and FF3. Untested elsewhere. Hope it helps. --Erik On Mon, Sep 29, 2008 at 10:23 AM, me-and-jQuery <[EMAIL PROTECTED]>wrote: > > I am searching the web and documentation and still can't find a > working solution. > > I have a table which rows has also id with metadata, for example <tr > data="{id:4}"> > > And now I want to select row with id 4.
