我还没有尝试过。请让我知道这对你有没有用。
function getScrollBarWidth () { var inner = document.createElement('p'); inner.style.width = "100%"; inner.style.height = "200px"; var outer = document.createElement('div'); outer.style.position = "absolute"; outer.style.top = "0px"; outer.style.left = "0px"; outer.style.visibility = "hidden"; outer.style.width = "200px"; outer.style.height = "150px"; outer.style.overflow = "hidden"; outer.appendChild (inner); document.body.appendChild (outer); var w1 = inner.offsetWidth; outer.style.overflow = 'scroll'; var w2 = inner.offsetWidth; if (w1 == w2) w2 = outer.clientWidth; document.body.removeChild (outer); return (w1 - w2);};
