get row with className

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

var rows = $('tr'开发者_运维技巧, tbl);

var rows = $('tr.classname:first', tbl);

or

var rows = $('tr.classname', tbl).first();

Docs here: http://api.jquery.com/category/selectors/

var firstRow = $('tr.classname:first', tbl)

You can use the :first selector along with the class selector,

Try this:

var rows = $('tr.someclass:first', tbl);

var row = $("tr.className:first", tbl); should do the trick.

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.

You can even use eq method of jquery if you want to loop through a list of elements.

var rows = $('tr.classname');
rows.eq(0);//first row
rows.eq(1);//second row
