get row with className

Question

How can you get the first row in a table with a specific className?

var rows = $(\'tr\', tbl);

Answer 1

If you keep the proprietary :first selector out of it, you'll have a valid querySelectorAll selector.

var rows = tbl.find('tr.someClass').slice( 0, 1 );

or

var rows = tbl.find('tr.someClass').eq( 0 );

Also, using the context parameter $( selector, context ) is just a slower way of using the find()[docs] method.
