javascript - 我怎样才能更有效地重写它

Question

我必须相信有更好的方法来编写下面的代码。提前致谢。

var hProtein = $('#protein-lbl');
var hCarb = $('#carb-lbl');
var hFat = $('#fat-lbl');
var hTotal = $('#totalCalories');

// Normal Calc vars
var nProtein = $('#protein-normal-lbl');
var nCarb = $('#carb-normal-lbl');
var nFat = $('#fat-normal-lbl');
var nTotal = $('#totalCalories-normal');

// Hide calculations until bodyweight is entered
hProtein.hide();
hCarb.hide();
hFat.hide();
hTotal.hide();
nProtein.hide();
nCarb.hide();
nFat.hide();
nTotal.hide();

Answer 1

也许给 HTML 元素一个类会起作用？

var $ele = $('.class-name');
$ele.hide();
