Как сказать обратно пропорционально в JQuery?

0

Я просто сделал div, который исправлен в правой части страницы и некоторого содержимого. Я хочу уменьшить размер этого div, когда мой контент больше, чем window.innerHeight(). И этот размер должен быть одним пикселем на каждом пикселе, увеличивающемся в высоте окна. Если кто-то не понял, может спросить меня в комментариях. Вот мой код:

<!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>

    ну, вам нужно было изменить размер окна, если вы хотите что-то сделать при изменении размера окна: p

Изменение: что-то вроде этого работает на то, что вы хотите, но вам придется строить какие-то константы. 25000 ниже - это просто случайная константа, которую я выбрал, чтобы увидеть, будет ли она работать. Константы, независимо от того, что вы выберете, будут тем, что действительно диктует изменение размера.

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

    Что ж, спасибо за то, что вы так добры. Не могли бы вы уточнить немного больше?
