javascript - 选择新评级值时如何删除先前选择的选项

Question

我正在使用 jquery-bar- rating https://github.com/antennaio/jquery-bar-rating

当用户选择新的评级值时，我想删除以前选择的选项。 这是脚本:

<script>
    $(function () {
        $('.rating').barrating('show',{
            theme: 'fontawesome-stars',
            initialRating: '0',
            onSelect: function (value, text, event) {
                if (typeof (event) !== 'undefined') {
                  $('#avis_nombre option:selected').removeAttr('selected');
                  document.querySelector('#avis_nombre option[value="' + value + '"]').setAttribute('selected', 'selected');
                }
            },
        });
    });
</script>

这是每次用户选择新的评分值时选择选项的输出

您的代码完美运行:

$(function() {
  $('#example').barrating('show', {
    theme: 'fontawesome-stars',
    initialRating: '0',
    onSelect: function(value, text, event) {
      if (typeof(event) !== 'undefined') {
        $('#avis_nombre option:selected').removeAttr('selected');
        document.querySelector('#avis_nombre option[value="' + value + '"]').setAttribute('selected', 'selected');
      }
    },
  });
});
