javascript - 通过 jquery 更改 webkit-slider-thumb 的背景图像

Question

我搜索了一段时间，但没有找到任何有用的东西。我有以下 css

 input[type="range"]::-webkit-slider-thumb {
       -webkit-appearance: none;
         width: 20px;
         height: 20px;
         border-radius: 10px;
         background-image: url('http://www.w3schools.com/html/smiley.png'),
         -webkit-gradient(
             linear,
             left top,
             left bottom,
             color-stop(0, #fefefe),
             color-stop(0.49, #dddddd),
             color-stop(0.51, #d1d1d1),
             color-stop(1, #a1a1a1)
         );
         background-size:20px;
         background-repeat: no-repeat;

现在我想借助 jquery 或我可以从 chrome 控制台测试的纯 javascript 将背景图像更改为其他图像 src。所以我有类似的东西:

`background-image: url('http://someotherimage/test.png'),`

谁能提到正确的语法。 感谢您期待好评。
