我认为，如果您将名称作为元数据添加到节点，并且在每次比较时都无需查看DOM，它将更快.记住，毕竟它们是O(n ² ).

I think if you add name as metadata to the node and eliminate looking through the DOM on every comparison, it'll be much faster. Remember, there's O(n²) of them after all.

$(function() { 
    $('.media-status-specie li')
        .each(function () {
            $(this).data('name', $(this).find(".english").text());
        })
});

.... 

function sortDescending1(a, b)  { 
    return $(a).data('name') < $(b).data('name') ? 1 : -1; 
}

免责声明:我认为，与其他任何开发人员一样，我不擅长猜测慢点，而是使用探查器来找到真正的性能杀手.

Disclaimer: It's my opinion, I'm no good at guessing slow points as any other developer out there, use profiler to find real performance killer.
