判断滚动条的需求在弹窗插件中使用比较多，当弹窗添加overflow: hidden时，如果页面比较长的话，添加这个属性之后页面会有晃动。
为了增强用户体验，通过判断是否有滚动条而添加 margin-left 属性以抵消 overflow: hidden 之后的滚动条位置。

判断是否有滚动条的方法
function hasScrollbar() {
  return document.body.scrollHeight > (window.innerHeight || document.documentElement.clientHeight);
}

计算滚动条宽度的方法
新建一个带有滚动条的 div 元素，通过该元素的 offsetWidth 和 clientWidth 的差值即可获得
