Question

我有两个使用radio按钮的星级评分系统。当用户点击星星时，该星星及其后面的所有星星都应该变成黄色。您可以在我的CSS代码中的注释中看到这一点（例如/* show gold star when clicked */）。

我认为它与可能出现的::before元素有关？但我对此并不完全确定：

＆＃13;

.rating {
  border: none;
  float: left;
}

.rating {
  margin: 0;
  padding: 0;
}

.rating input {
  display: none;
}

.rating label:before {
  margin: 5px;
  font-size: 1.25em;
  font-family: FontAwesome;
  display: inline-block;
  content: "\f005";
}

.rating .half:before {
  content: "\f089";
  position: absolute;
}

.rating label {
  color: #ddd;
  float: right;
}

.rating input:checked~label,

/* show gold star when clicked */

.rating:not(:checked) label:hover,

/* hover current star */

.rating:not(:checked) label:hover~label {
  color: #FFD700;
}


/* hover previous stars in list */

.rating input:checked+label:hover,

/* hover current star when changing rating */

.rating input:checked~label:hover,
.rating label:hover~input:checked~label,

/* lighten current selection */

.rating input:checked~label:hover~label {
  color: #FFED85;
}

Answer 1

如上所述，这在纯CSS中是可以实现的，但它确实需要添加ID和属性，并重新构建HTML以使标签和单选按钮成为兄弟姐妹，如下所示：

＆＃13;

$(document).on('click', 'fieldset label', function () {
    var that = this;
    setTimeout(function() {
    console.log('hidden val=',$(that).parent().find("input[type='hidden']").val());
    console.log('checked val=',$(that).parent().find("input[type='radio']:checked").val());
    },1);
});

＆＃13;

.rating {
  border: none;
  float: left;
}

.rating {
  margin: 0;
  padding: 0;
}

.rating input {
  display: none;
}

.rating label:before {
  margin: 5px;
  font-size: 1.25em;
  font-family: FontAwesome;
  display: inline-block;
  content: "\f005";
}

.rating .half:before {
  content: "\f089";
  position: absolute;
}

.rating label {
  color: #ddd;
  float: right;
}

.rating input:checked~label,

/* show gold star when clicked */

.rating:not(:checked) label:hover,

/* hover current star */

.rating:not(:checked) label:hover~label {
  color: #FFD700;
}


/* hover previous stars in list */

.rating input:checked+label:hover,

/* hover current star when changing rating */

.rating input:checked~label:hover,
.rating label:hover~input:checked~label,

/* lighten current selection */

.rating input:checked~label:hover~label {
  color: #FFED85;
}
