[jQuery] Re: Metadata parameter as selector

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:

Seems to work in IE7 and FF3. Untested elsewhere.

 

Hope it helps.

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. I was trying many ways but no
success for now. For example:

$.metadata.setType("attr", "data")
$("table tr.id:4").metadata().remove();


Anyway, is this possible with metadata at all? Thanks for any help.
