求一个正则配置

怎么用正则获取div里style的left和top的
39.73354231974922和94.35736677115987这两个值，不包括%

<div class="coordinatebox" index="1" style="left:39.73354231974922%;top:94.35736677115987%"><span></span><h3 class="labeltpl" data-label="标签1">标签1</h3></div>

---

var reg = /style="left:([\d\.]+)[\s\S]+top:([\d\.]+)/;
var matches = '<div class="coordinatebox" index="1" style="left:39.73354231974922%;top:94.35736677115987%"><span></span><h3 class="labeltpl" data-label="标签1">标签1</h3></div>'.match(reg);

console.log('left: %s,top: %s',matches[1],matches[2])

---

var s = '<div class="coordinatebox" index="1" '
    + 'style="left:39.73354231974922%;top:94.35736677115987%">'
    + '<span></span><h3 class="labeltpl" data-label="标签1">'
    + '标签1</h3></div>';
s.match(/\d+\.?\d+(?=%)/g); // ["39.73354231974922", "94.35736677115987"]
