javascript - 单击图像时 Jquery 悬停图像问题

Question

我遇到的问题是，当我单击所需的图像评级时，当我在单击所需的评级后将鼠标悬停在图像上时，无法显示评级较低的图像。

例如，假设我点击了 3 星评级图像，我可以悬停并显示 4 星评级和 5 星评级图像而无需单击它们，但是当我将鼠标悬停在图像上时，我无法显示 1 星评级和 2 星评级的图像在我点击 3 星评级图片后。

我添加了一个变量，这是你的结果代码:

$(document).ready(function() {
  var rating;
      $('.rating-pick li')
        .on('mouseenter touchstart', function() {
          var classSuffix = $(this).find('input').attr('id').split('-')[1];
          $('.rating-pick').prevAll().addBack().addClass('rating-' + classSuffix);
          $('.rating-pick').nextAll().removeClass('notrated');
          $('.rate').text($(this).data('desc'));


        rating = $('.rating-pick').attr("class").split(" ")[1];
        $('.rating-pick').removeClass(rating);
        })
        .on('mouseleave touchend', function() {
          var classSuffix = $(this).find('input').attr('id').split('-')[1];
          $('.rating-pick').prevAll().addBack().removeClass('rating-' + classSuffix);
          $('.rate').text($('.rate').attr('data-desc'));

        $('.rating-pick').addClass(rating);
        })
        .on('change click', function(e) {
          e.preventDefault();
          e.stopPropagation();
          $('.rate').attr('data-desc', $(this).attr('data-desc'));
          var classSuffix = $(this).find('input').attr('id').split('-')[1];
          $('ul.rating-pick').removeClass().addClass('rating-pick rating-' + classSuffix);
          $(this).off('mouseenter touchstart mouseleave touchend');
        });
    });
