Question

我想在滑块值更改时更改右上角的星形项目，例如，当滑块值为1时，应该有1个星，对于值2，应该有2个星，依此类推，最多5个星保持如果可能，相同的html结构。我保持slide: function() {}为空，因为我不知道如何在值更改时创建函数。

$(document).ready(function() {
  $('.slider-rating').slider({
    range: true,
    min: 1,
    max: 5,
    values: [3, 5],
    slide: function() {

    }
  });
});

@import

@import

.control-group {
	margin-bottom: 10px;
  padding: 50px 20px;
}

.control-group .controls {
	margin: 5px 0;
}

    <div class="control-percentage pull-right">

        <i class="fa fa-star"></i>
        <i class="fa fa-star"></i>
      </span>
    </div>
  </div>
  <div class="controls">
    <div class="slider slider-rating"></div>
  </div>
</div>

添加了两颗星，然后我这样做了：

$(document).ready(function() {
  $('.slider-rating').slider({
    range: true,
    min: 1,
    max: 5,
    values: [3, 5],
    slide: function(x,y) {
        var stars = $('.slider-rating-label').find('i');
        //clear all
        $.each(stars, function (index, value) {
            $(value).removeClass().addClass('fa fa-star-o');
        });
        //fill by slider value
        for (var i = 0; i < y.value; i++) {
            $(stars[i]).removeClass().addClass('fa fa-star');
        }
    }
  });
});

使用带有Fontawesome的jQuery UI滑块更改星级
