<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。进度条使用帮助属性 - box-shadow。正如你可以看到这个属性的价值太大，我不知道如何操纵它。你能帮帮我这个房产吗？可能是生成高级box-shadow的特殊服务吗？

Answer 1

好吧，我找到了一个使用gradient代替box-shadow的解决方案，您可以使用background-size控制进度条的宽度，请查看此演示：

＆＃13;

＆＃13;

$('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');

＆＃13;

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;
}

＆＃13;

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>


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