javascript - jquery:检查当前切换的类

Question

所以，这是我的代码

     $(".heart.fa").click(function() {
          $(this).toggleClass("fa-heart fa-heart-o");

//Wanna check here is its fa-heart or fa-heart-o

           var row = $(this).closest("i");
           var rowId = row.attr("id");
            alert(rowId);

        });

<div>
  <i id= '".$i."' class='heart fa fa-heart-o'></i>
</div>

想要检查此函数当前是否为 fa-heart-o 或 fa-heart

Answer 1

hasClass 函数可能就是您想要的 https://api.jquery.com/hasclass/

所以你会做这样的事情:

if($(this).hasClass('fa-heart-o')){
//logic for having fa-heart-o
}
else{
//logic for having fa-heart
}
