<input type="range" min="0" max="100" value="40" />

但是如果我们将输入的宽度更改为 640px - 红色进度条工作不正确。进度条与帮助属性一起工作 - box-shadow。如您所见，此属性的值太大，我不知道如何处理它。你能帮我处理这处特性吗？可能是生成高级 box-shadow 的特殊服务？

Answer 1

好吧，我为您找到了使用 gradient 的解决方案而不是 box-shadow您可以使用 background-size 控制进度条的宽度看看这个演示:

$('input[type=range]').on('input', function(e){
  var min = e.target.min,
      max = e.target.max,
      val = e.target.value;
  
  $(e.target).css({
    'backgroundSize': (val - min) * 100 / (max - min) + '% 100%'
  });
}).trigger('input');

html, body {
    height: 100%;
    padding: 0;
    margin: 0;
}

input[type=range] {
    margin: auto;
    outline: none;
    padding: 0;
    width: 640px;
    height: 2px;
    background-color: #dedede;
    background-image: -webkit-gradient(linear, 50% 0%, 50% 100%, color-stop(0%, #ff1100), color-stop(100%, #ff1100));
    background-size: 50% 100%;
    background-repeat: no-repeat;
    border-radius: 10px;
    cursor: pointer;
    -webkit-appearance: none;
}

input[type=range]::-webkit-slider-runnable-track {
    box-shadow: none;
    border: none;
    background: transparent;
    -webkit-appearance: none;
}


input[type=range]::-webkit-slider-thumb {
  height: 18px;
  width: 28px;
    border: 0;
    background: #fff;
    border: 1px solid #777;
    border-radius: 8px;
    box-shadow: 0 0 1px 0px rgba(0,0,0,0.1);
    -webkit-appearance: none;
}
