jQuery每个仅返回第一个找到的元素

Question

var x = $(".tabularData tr").each(function(){
        if($(this).hasClass("even")||$(this).hasClass("odd")){
            RETURN ONLY FIRST FOUND ELEMENT, WEATHER EVEN OR ODD
            CURRENT CODE IS RETURNING ALL ELEMENTS
            //return $(this);
        }
});

return $(this) is return all elements with even|odd whereas i need only return first found element.

Answer 1

If I 'm not misunderstanding your intent, you can do this much more easily with

var $x = $(".tabularData tr").filter(".odd, .even").first();

However, do you really need the "odd or even" test? Since every row is either odd or even, it sounds like it would be much simpler to just do

var $x = $(".tabularData tr:first");
