Question

我想在onmouseover或使用图像映射自动滚动特定元素。我还想隐藏该div的滚动条。问题是......

我不明白该怎么做。我已经学习了几个星期的JavaScript，我只学习了无用的部分。什么都不适用于网页设计，即。我确实谷歌它并没有给我我正在寻找的确切答案，也没有能够调整这些例子为我工作。

代码在jsfiddle.net上，除非我违反了一条不成文的规则，请告诉我，我会发布链接。请拜托！不要只是给我一个答案，因为我是初学者。请解释你的解决方案。非常感谢你！

决定添加代码，因为我在执行此操作之前已立即做出响应。

Answer 1

如何隐藏滚动条：

在div上设置css属性overflow为hidden：

<div style="overflow:hidden"></div>

如何滚动div：

该元素具有scrollTop属性，该属性是元素滚动的像素数量。您可以通过分配此属性来滚动元素：

var div = document.getElementById(someId);
div.scrollTop = 50;

如何在鼠标悬停时执行某些操作：

var div = document.getElementById(someId);
div.onmouseover = function() {
    // do something here
};
