星级评定系统悬停

Question

目前我正在为网上商店制作评级系统。基本上我希望它如何工作：

如果访问者之前从未评价过：

访客悬停在星星上
上一个和当前的星星将为黄色，下一个星星为灰色（用 class 完成）
如果访问者离开悬停，将所有星星重置为旧状态
如果访问者点击一颗星，保存它，计算下一个星值并更新数组。

我使用的字体很棒，所以我没有使用任何图像。现在的问题是，如果我将鼠标悬停在一颗星星上，它会起作用，但如果我想从一颗星星移动到另一颗星星，它就会出现故障（因为星星之间有一点间隙，这意味着它会先重置星星）。

jsfiddle: https://jsfiddle.net/uappvz3y/

JS:

var current_star_statusses = [];

star_elements = $('.fa-star');

star_elements.each(function(i, elem)
{
    current_star_statusses.push($(elem).hasClass('yellow'));
});

star_elements.mouseenter(changeRatingStars);
star_elements.mouseleave(resetRatingStars);

/**
 * Changes the rating star colors when hovering over it.
 */
function changeRatingStars()
{
    // Current star hovered
    var star = $(this);

    // Removes all colors first from all stars
    $('.fa-star').removeClass('gray').removeClass('yellow');

    // Makes the current hovered star yellow
    star.addClass('yellow');

    // Makes the previous stars yellow and the next stars gray
    star.parent().prevAll().children('.fa-star').addClass('yellow');
    star.parent().nextAll().children('.fa-star').addClass('gray');
}

/**
 * Resets the rating star colors when not hovered anymore.
 */
function resetRatingStars()
{
    star_elements.each(function(i, elem)
    {
        $(elem).removeClass('yellow').removeClass('gray').addClass(current_star_statusses[i] ? 'yellow' : 'gray');
    });
}

HTML:

<ul class="list-inline rating-list">
    <li><i class="fa fa-star yellow"></i></li>
    <li><i class="fa fa-star yellow"></i></li>
    <li><i class="fa fa-star yellow"></i></li>
    <li><i class="fa fa-star yellow"></i></li>
    <li><i class="fa fa-star gray"></i></li>
</ul>

CSS:

.fa-star:before {
    content: "\f005";
}

.rating-list li i.yellow {
    color: #FFD700;
}

.rating-list li i.gray {
    color: #bbb;
}

.list-inline>li {
    display: inline-block;
    padding-right: 5px;
    padding-left: 5px;
}

.rating-list li {
    padding: 0px;
}
.fa {
    display: inline-block;
    font: normal normal normal 14px/1 FontAwesome;
    font-size: inherit;
    text-rendering: auto;
    -webkit-font-smoothing: antialiased;
    -moz-osx-font-smoothing: grayscale;
    transform: translate(0, 0);
}

我知道有很多库可以使它更容易，但如果可以的话，我想保留我自己的代码。

Answer 1

我改了这4行代码

star_elements = $('.fa-star').parent();

star_elements.find(".fa-star").each(function(i, elem) {
  current_star_statusses.push($(elem).hasClass('yellow'));
});

star_elements.find(".fa-star").mouseenter(changeRatingStars);
star_elements.find(".fa-star").mouseleave(resetRatingStars);

所以现在 star_element 是 li。

此外，如果您喜欢 jsfiddle，这里有一个 link

var current_star_statusses = [];

star_elements = $('.fa-star').parent();

star_elements.find(".fa-star").each(function(i, elem) {
  current_star_statusses.push($(elem).hasClass('yellow'));
});

star_elements.find(".fa-star").mouseenter(changeRatingStars);
star_elements.find(".fa-star").mouseleave(resetRatingStars);

/**
 * Changes the rating star colors when hovering over it.
 */
function changeRatingStars() {
  // Current star hovered
  var star = $(this);

  // Removes all colors first from all stars
  $('.fa-star').removeClass('gray').removeClass('yellow');

  // Makes the current hovered star yellow
  star.addClass('yellow');

  // Makes the previous stars yellow and the next stars gray
  star.parent().prevAll().children('.fa-star').addClass('yellow');
  star.parent().nextAll().children('.fa-star').addClass('gray');
}

/**
 * Resets the rating star colors when not hovered anymore.
 */
function resetRatingStars() {
  star_elements.each(function(i, elem) {
    $(elem).removeClass('yellow').removeClass('gray').addClass(current_star_statusses[i] ? 'yellow' : 'gray');
  });
}

.fa-star:before {
  content: "\f005";
}

.rating-list li i.yellow {
  color: #FFD700;
}

.rating-list li i.gray {
  color: #bbb;
}

.list-inline>li {
  display: inline-block;
  padding-right: 5px;
  padding-left: 5px;
}

.rating-list li {
  padding: 0px;
}

.fa {
  display: inline-block;
  font: normal normal normal 14px/1 FontAwesome;
  font-size: inherit;
  text-rendering: auto;
  -webkit-font-smoothing: antialiased;
  -moz-osx-font-smoothing: grayscale;
  transform: translate(0, 0);
}

Answer 2

您可以使用纯 CSS 进行星级评分。向右浮动星星，并为具有填充的 li 应用悬停效果。

.rating-list li {
  float: right;
  color: #ddd;
  padding: 10px 5px;
}

.rating-list li:hover,
.rating-list li:hover ~ li {
  color: #ffd700;
}

.rating-list {
  display: inline-block;
  list-style: none;
}

<link href="https://maxcdn.bootstrapcdn.com/font-awesome/4.7.0/css/font-awesome.min.css" rel="stylesheet"/>

<ul class="list-inline rating-list">
  <li><i class="fa fa-star" title="Rate 5"></i></li>
  <li><i class="fa fa-star" title="Rate 4"></i></li>
  <li><i class="fa fa-star" title="Rate 3"></i></li>
  <li><i class="fa fa-star" title="Rate 2"></i></li>
  <li><i class="fa fa-star" title="Rate 1"></i></li>
</ul>

Answer 3

有一个更简单的解决方案：改为在 .fa 元素上使用填充，并为列表项使用 float: left，这意味着每个星号之间没有间距。

这几条规则足以达到你想要的效果：

.list-inline {
  list-style: none;
  padding: 0;
  margin: 0;
  overflow: hidden;
}
.list-inline > li {
  float: left;
}
.rating-list li {
  padding: 0px;
}
.rating-list li .fa {
  padding-right: 5px;
}

这是一个概念验证示例，您的 JS 代码保持不变：

$(function() {

    var current_star_statusses = [];

    star_elements = $('.fa-star');

    star_elements.each(function(i, elem) {
      current_star_statusses.push($(elem).hasClass('yellow'));
    });

    star_elements.mouseenter(changeRatingStars);
    star_elements.mouseleave(resetRatingStars);

    /**
     * Changes the rating star colors when hovering over it.
     */
    function changeRatingStars() {
      // Current star hovered
      var star = $(this);

      // Removes all colors first from all stars
      $('.fa-star').removeClass('gray').removeClass('yellow');

      // Makes the current hovered star yellow
      star.addClass('yellow');

      // Makes the previous stars yellow and the next stars gray
      star.parent().prevAll().children('.fa-star').addClass('yellow');
      star.parent().nextAll().children('.fa-star').addClass('gray');
    }

    /**
     * Resets the rating star colors when not hovered anymore.
     */
    function resetRatingStars() {
      star_elements.each(function(i, elem) {
        $(elem).removeClass('yellow').removeClass('gray').addClass(current_star_statusses[i] ? 'yellow' : 'gray');
      });
    }
 });

.fa-star:before {
  content: "\f005";
}

.rating-list li i.yellow {
  color: #FFD700;
}

.rating-list li i.gray {
  color: #bbb;
}

.list-inline {
  list-style: none;
  padding: 0;
  margin: 0;
  overflow: hidden;
}
.list-inline>li {
  float: left;
}

.rating-list li {
  padding: 0px;
}
.rating-list li .fa {
  padding-right: 5px;
}

.fa {
  display: inline-block;
  font: normal normal normal 14px/1 FontAwesome;
  font-size: inherit;
  text-rendering: auto;
  -webkit-font-smoothing: antialiased;
  -moz-osx-font-smoothing: grayscale;
  transform: translate(0, 0);
}
