从任何地方滚动一个 div [英] Scroll a div from everywhere

问题描述

我不知道如何描述我的担忧，这就是我在 Google 上找不到任何内容的原因.我想绘制一个 div 立即聚焦在页面调用上，如果您按下滚轮也可以滚动此 div.无论您是将鼠标悬停在 div 上还是在外面.

I do not know how to describe my concern and thats why I could not find anything on Google. I want to draw a div is focused at page call immediately and if you press the scroll wheel to scroll this div also. Whether you are with the mouse over the div or outside.

对不起，我的英语不好，谷歌翻译......尴尬^_^

sorry for my bad english, google translator .... embarrassing ^_^

推荐答案

如果你想滚动 div，即使鼠标在页面上的其他位置，试试这个插件 https://github.com/brandonaaron/jquery-mousewheel.这是一个假设您的 div 具有内容 ID 的示例:

If you want to scroll the div even if the mouse is else where on the page try this plugin https://github.com/brandonaaron/jquery-mousewheel. Here is an example assuming your div has an id of content:

$(function() {
    var $target = $('#content');
    $("body").mousewheel(function(event, delta) {
      $target.scrollTop($target.scrollTop() - (delta * 30));
      event.preventDefault();
   });
});
