You can use add : jqId1.add(jqId2).show(); But don’t make your code too complex just to avoid querying “#id1,#id2” : this selector relies on getElementById and is very fast. You can use each cycle: $([jqId1, jqId2]).each( function(){ $(this).show(); }); As answered here: Select multiple jQuery objects with .add()
:eq() Select the element at index n within the matched set. The index-related selectors (:eq(), :lt(), :gt(), :even, :odd) filter the set of elements that have matched the expressions that precede them. They narrow the set down based on the order of the elements within this matched set. For example, if elements are first selected … Read more
Ok. I found a solution: $(‘table tr td:nth-child(‘+ownerIndex+’)’)
To elaborate on the comments above: You cannot write: next(“a”), because next() only tries to match the very next element. It will hit the <br> element and match nothing. closest(“a”) , because closest() walks up the ancestor chain, starting with the element itself, and therefore will miss the <a> elements. You can write: next().next(), as … Read more

(note that you can change the “initial” state with the attr function, but it’s bad practice, you should … Read more
You have to add an empty option (i.e. <option></option>) as a first element to see a placeholder. From Select2 official documentation : “Note that because browsers assume the first option element is selected in non-multi-value select boxes an empty first option element must be provided (<option></option>) for the placeholder to work.” Example: <select id=”countries”> <option></option> … Read more
Update 10/18/2012 CsQuery is now in release 1.3. The latest release incorporates a C# port of the validator.nu HTML5 parser. As a result CsQuery will now produce a DOM that uses the HTML5 spec for invalid markup handling and is completely standards compliant. Original Answer Old question but new answer.

The truth of the matter is that jQuery simply does not have a particularly elegant way to do what you want. While chaos’ answer does work, you have to wonder whether the complicated selector (that would be about as slow as a selector can be in a complicated webpage) is worth it over the more … Read more
You’re thinking too complicated. It’s actually just $(‘#’+openaddress).
Use the attribute-starts-with selector: $(‘[id^=”content_”]’).hide(); To limit the search to elements within extra_content: $(‘#extra_content [id^=”content_”]’).hide();
