如上图，我用css重置了<input type="range">的样式,现在我想获取到滑块的left值，可以实现吗？代码如下 {代码...}

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();

建议楼上用 range.onmousemove = function(){}....
