如何使:在IE工作状态的工作? [英] How to make :active state work in IE?
问题描述
我有一个按钮,在我的HTML表单,需要改变它的背景图片使用CSS被点击时它。它的工作原理完美在FF但似乎IE犯规支持:主动
状态。
下面是我的code:
HTML
<按钮类='按钮'>点击ME< /按钮>
CSS:
.button {
宽度:118px;
高度:33px;
背景:网址(/images/admin/btn.png)不重复顶部中心;
边界:无;
概述:无;
}
.button:积极{
背景位置:底部中心;
}
这是在早期版本的IE浏览器的一个已知的bug(我认为他们解决了它IE8)。我通常用JavaScript解决这个问题(以及相应的悬停的问题)。我附上两个事件处理程序的元素 - 鼠标按下设置一个附加的类(如按钮,激活的东西)和鼠标松开去掉的类。在jQuery的将是这样的:
$('按钮')的mousedown(函数(){$(本).addClass(按钮主动');});
$('按钮')的mouseup(函数(){$(本).removeClass(按钮主动');});
然后,刚才那类添加到CSS规则,就像这样:
.button:主动,.button活跃{
背景位置:底部中心;
}
有一个难看一点,是的,但你能指望什么 - 这是IE浏览器。它不能是pretty。
I have a button in my html form and need to change it's background image when it is clicked using css. it works perfect in FF but it seems that IE doesnt support :active
state.
Here is my code:
HTML:
<button class='button'>Click Me</button>
CSS:
.button {
width: 118px;
height: 33px;
background: url(/images/admin/btn.png) no-repeat center top;
border: none;
outline: none;
}
.button:active {
background-position: center bottom;
}
This is a known bug in earlier versions of IE (I think they solved it in IE8). I usually solve this (as well as the corresponding "hover" problem) with javascript. I attach two event handlers to the element -- "mousedown" to set an additional class (something like "button-active") and "mouseup" to remove the class. In jQuery it would be something like this:
$('.button').mousedown(function() { $(this).addClass('button-active'); });
$('.button').mouseup(function() { $(this).removeClass('button-active'); });
Then, just add that class to the css rule, like so:
.button:active, .button-active {
background-position: center bottom;
}
A little ugly, yes, but what do you expect -- it's Internet Explorer. It can't be pretty.
