javascript - 当单击一个图像然后单击另一个图像时，jquery 悬停图像问题悬停时不会显示单击的第一个图像

Question

现在我遇到了一个新问题，当我单击所需的图像评级，然后单击另一个所需的评级，然后我决定将鼠标悬停在我单击的第一个评级上时，现在我第一次单击的星级图像评级将不会显示。

例如，假设我点击了 3 星评级图片，然后我点击了 1 星评级图片，然后我将鼠标悬停在 3 星评级图片上，鼠标悬停时该图片不会出现。

HTML

    <ol>
      <li>
        <ul class="rating-pick notrated">

这是更新后的代码:

$(document).ready(function() {
      var rating = "notrated";
      $('.rating-pick li')
        .on('mouseenter touchstart', function() {
          $(this).parent().removeClass($(this).parent().attr("class").split(" ")[1]);
          var classSuffix = $(this).attr('id').split('-')[1];
          $('.rating-pick').addClass('rating-' + classSuffix);
          $('.rate').text($(this).data('desc'));
        })
        .on('mouseleave touchend', function() {
          var classSuffix = $(this).attr('id').split('-')[1];
          $('.rate').text($('.rate').attr('data-desc'));
          $('.rating-pick').attr("class", "").addClass("rating-pick " + rating)
        })
        .on('change click', function(e) {
          e.preventDefault();
          e.stopPropagation();
          $('.rate').attr('data-desc', $(this).attr('data-desc'));
          rating = "rating-" + $(this).attr("id").split("-")[1];
          $('.rating-pick').removeClass("notrated").addClass(rating);
        });
    });

Here is the JSFiddle demo

您的代码中的问题是由于元素上的事件被关闭了。

我删除了该代码并实现了变通办法。
