css3新增pointer-events属性可阻止hover、active、onclick等触发事件

CSS3的pointer-events属性可以阻止用户的点击、hover和active等事件,防止重复提交或允许鼠标穿透。文章详细解释了pointer-events的auto和none值,并指出其在Firefox、Chrome和Safari的兼容性,但在旧版IE中不受支持。

pointer-events 更像是JavaScript,它能够:

  • 阻止用户的点击动作产生任何效果

  • 阻止缺省鼠标指针的显示

  • 阻止CSS里的 hover 和 active 状态的变化触发事件

  • 阻止JavaScript点击动作触发的事件

实际代码使用中案例:

1、提交页面,提交按钮点击后,添加这个样式属性(style="pointer-events"),来防止重复提交。 @camnpr

2、一些层的绝对定位,覆盖按钮,穿透可以点击它。等等。

来看下具体用法:

pointer-events:  auto | none | visiblePainted | visibleFill | visibleStroke | visible | painted | fill | stroke | all | inherit

pointer-events属性有很多值,但是对于浏览器来说,只有auto和non两个值可用,其它的几个是针对SVG的(本身这个属性就来自于SVG技术)。

pointer-events属性值详解

  • auto——效果和没有定义pointer-events属性相同,鼠标不会穿透当前层。在SVG中,该值和visiblePainted的效果相同。

  • none——元素不再是鼠标事件的目标,鼠标不再监听当前层而去监听下面的层中的元素。但是如果它的子元素设置了pointer-events为其它值,比如auto,鼠标还是会监听这个子元素的。

  • 其它属性值为SVG专用,这里不再多介绍了。

浏览器兼容性

Firefox 3.6+和chrome 2.0+ 以及safari 4.0+都支持这个CSS3属性,IE6/7/8/9都不支持(IE11又支持,不过很好的一点是在ie中给a加disabled 点击事件自动无效。),Opera在SVG中支持。 但是 该属性HTML中 不支持
