如何使用JQuery获得不包括水平滚动条的<DIV>的高度?

element.clientHeight . 在jQuery中,这类似于:

var heightWithoutScrollbar = $('#outer')[0].clientHeight;

我找到了一个可以 get the width of a scrollbar

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);  
};

页面将提示滚动条的宽度。
