border-radius和：hover状态区域问题 [英] Border-radius and :hover state area issue

问题描述

我在无处不在回答这个问题，但无处可以找到任何关于它。任何人都可以告诉我，我们是否可以影响收到item hover border-radius属性的区域。这样，改变，如颜色的影响发生后，击中一个实际区域查看项目？不要阻止DOM中的实际存在是一个正方形？

I'm looking everywhere to answer this question but nowhere can I find anything about it. Can anyone tell me whether we can affect the area which received the item hover border-radius property. So that the effect of changes such as color took place after hitting a real area viewed item? Do not block that physically exists in the DOM as a square?

这是简单的img。

推荐答案

你可以使用SVG和指针事件：

Well, you can use SVG and pointer-events:

或者只是使用SVG，也许有一些像Raphäel这样的框架。

Or just use SVG, maybe with some framework like Raphäel.

或者玩一个地图，让我试试。 ..

Or maybe play with a map, let me try that...

HTML

<img class="div" src="http://images2.wikia.nocookie.net/__cb20100822143346/runescape/images/2/21/1x1-pixel.png" usemap="hack"/>

<map name="hack">
    <area shape="circle" coords="200,200,200" />
</map>

JS

$('area').hover(function(event) {

    $('img.div').toggleClass('hover');

});

LOOK MOM，NO JS：

http://jsfiddle.net/coma/nawAE/12/

.div {
    display: block;
    font-size: 0;
    width: 400px;
    height: 400px;
    background-color: red;
    border-radius: 50%;
}

map:hover + img {
    background-color: blue;
}
