切换 Class 与字体真棒不工作

Question

I have multiple buttons, when a like button is clicked I would like the font awesome icon to switch as well, however, the way I have it set up the font awesome icon just disappears, but I can see the class change. Not sure where to go from here.

 $("button").click(function() { $('#like' + this.id).toggleClass("fa-regular fa-thumbs-up"); });

Answer 1

If you want to change icon/style just add other class to toggleClass like:

 $("button").click(function() { $('#like'+this.id).toggleClass("fa-solid fa-thumbs-up fa-regular fa-thumbs-up"); });
