我正在尝试建立一个星级评分系统,我有这个代码,我想对它进行一些更改,在用户点击星星后它会显示一个警报,显示有多少个星星,它会重置颜色,我想要的是在用户点击它之后停留的颜色,并用星空下的div替换警报,这是我的代码:
$(function() {
$("div.star-rating > s, div.star-rating-rtl > s").on("click", function(e) {
var numStars = $(e.target).parentsUntil("div").length+1;
alert(numStars + (numStars == 1 ? " star" : " stars!"));
});
});
.star-rating s:hover {
color: red;
}
.star-rating-rtl s:hover {
color: red;
}
.star-rating s,
.star-rating-rtl s {
color: black;
font-size: 50px;
cursor: default;
text-decoration: none;
line-height: 50px;
}
.star-rating {
padding: 2px;
}
.star-rating-rtl {
background: #555;
display: inline-block;
border: 2px solid #444;
}
.star-rating-rtl s {
color: yellow;
}
.star-rating s:hover:before, .star-rating s.rated:before {
content: "\2605";
}
.star-rating s:before {
content: "\2606";
}
.star-rating-rtl s:hover:after, .star-rating-rtl s.rated:after{
content: "\2605";
}
.star-rating-rtl s:after {
content: "\2606";
}

请参阅 .active在CSS中查找添加类，以查找其中的更改。

$(function() {
$("div.star-rating > s, div.star-rating-rtl > s").on("click", function(e) {
// remove all active classes first, needed if user clicks multiple times
$(this).closest('div').find('.active').removeClass('active');
