Question

我只是在页面的右边和一些内容上修改了一个div。 我想要的是每当我的内容大于window.innerHeight()时，减小此div的大小。并且这个调整大小必须是窗口高度每增加一个像素的一个像素。如果有人不理解，可以在评论中问我。这是我的代码：

<!DOCTYPE html>
<html>
<head>
    <title>Custom ScrollBar</title>
    <script type="text/javascript" src="jQuery.js"></script>
    <style type="text/css">
        #scrollBar{
            height: 200px;
            width: 5px;
            background: grey;
            position: fixed;
            top: 0px;
            right: 0;
        }
    </style>
</head>
<body>

编辑：这样的东西适用于你想要的东西，但是你将不得不构建某种常量。下面的25000只是我选择的一个随机常数，看它是否会起作用。无论你选择什么，常数都将成为真正决定尺寸变化的因素。

$(window).bind("load resize", function () {
    var changeHeight, example;
    changeHeight = function ($div) {
        var inverse, winHeight;
        winHeight = $(window).height();
        inverse = 25000 / winHeight;
        return $div.height(inverse);
    };
    example = $('.example-div');
    return changeHeight(example);
});

怎么说在jQuery中反比例？
