通过jquery更改webkit-slider-thumb的背景图片

Question

我搜索了一会儿,但找不到任何有用的东西.我有以下的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;

}

现在我想通过jquery或普通javascript的帮助将背景图像更改为其他图像src,我可以从chrome console中测试.所以我有类似的东西:

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

任何人都可以提到正确的语法.感谢您的好评.

我正在发布解决方案,对于任何面临同样问题的人都有用.因为我想动态更改-webkit-slider-thumb的CSS,所以我做了类似这样的事情我使用了一个类来输入并添加了css for这个班是这样的

.first_class::-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;
             background-position: 50%;
         }

我还在另一个类名下添加了另一组css

.second_class::-webkit-slider-thumb {
       -webkit-appearance: none;
         width: 20px;
         height: 20px;

         border-radius: 10px;
         background-image: url('http://someotherimage/test.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;
         background-position: 50%;
     }

然后使用Jquery我每次需要更改css时都更改了类,即如果我删除first_class并添加second_class到输入,它将更改-webkit-slider-thumb的图像 谢谢所有试图帮助的人.
