html5中input有增加type=range。这为拖动滑块提供了很大的便利。下面是他的属性：
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
<style>
.main{ position: relative;width: 500px;}
#range {
-webkit-appearance: none;
background: #999;
height: 3px;
outline: none;
margin: 0;
width: 500px;
}
input[type=range]::-webkit-slider-thumb{
-webkit-appearance: none;
width: 20px;
height: 20px;
border-radius: 50%;
background: red;
}
p{
position: absolute;
width: 0px;
height: 3px;
background: green;
top: -2px;
left: 0;
}
.range{
position: relative;
}
.value{
padding: 10px;
background: #ffebc7;
font-size: 40px;
text-align: center;
margin: 0 auto;
}
</style>
</head>
<body>
<div class="main">
<div class="value"></div>
<div class="range">
<input type="range" max="10" min="0" id="range" step="0.1" value="0">
<p></p>
</div>
</div>
</body>
<script src="http://apps.bdimg.com/libs/jquery/2.1.4/jquery.min.js"></script>
<script>
$(".value").html("0")
var rangeSwitch=function () {
var x=$("#range").val();
$("p").css({"width":(x/10)*500*0.96})//乘的0.96是因为要不然绿色的颜色会有部分盖住滑动按钮（500-20）/500=0.96;
$(".value").html(x)
}
$("#range").on("input",rangeSwitch)
</script>
</html>
