如上图,我用css重置了的样式,现在我想获取到滑块的left值,可以实现吗?
代码如下

<style>

}
input[type=range]:focus,
input[type=range]:active {

}
/*滑块*/

</div>
</body>
</html>
var range = document.getElementById('range');
var span = document.getElementById('span');
var cs = getComputedStyle(range, 0);
range.onchange = function() {
span.style.left = ((range.value - 1000) * parseInt(cs.width) / 9000
+ 18 - range.value/300) + "px";
span.innerHTML = range.value;
};
range.onchange();
