更新因此，在所有人的帮助下，我设法获得了想要的结果(每次单击不同的图标，只有单击的图标具有不同的颜色).最重要的是，我很好奇是否存在使用功能"之类的方法来执行我现在喜欢的重复性或混乱程度较小的方法.如果能得到一些提示，我将不胜感激.

UPDATE So Thanks to everyone's help, I managed to get the result I wanted (Every time I click a different icon, only the icon I click has the different color). On top of that, I am curious if there is a less repetitive or messy way to execute what I have now like using "Function" or something. I would appreciate if I can get some tips on it.

推荐答案

还有其他一些用于更改FA图标的选项.关键字 this 表示垃圾. .property 或 .method()/.function()引用该图标.

Here's some other options to change an FA icon. The keyword this represents garbage. The .property or .method()/.function() references the icon.

.children

.querySelector()

.getElementsByTagName()

.classList

.firstElementChild

var garbage = document.getElementById("garbage");

garbage.addEventListener("click", function() {
  this.children[0].style.color = "#66c144";
  this.querySelector('.fas').style.fontSize = '3rem';
  this.getElementsByTagName('I')[0].classList.toggle('fa-spin');
  this.firstElementChild.style.transition = 'color 1.5s ease 1.25s, font-size 0.75s ease-out';
}, false);
