1、引子

css3的出现让浏览器的表现更加的丰富多彩,表现冲击最大的就是动画了,在日常书写动画的时候,很有必要去事先判断浏览器是否支持,尤其是在写CSS3动画库的时候。比如transition的animation-play-state,就只有部分浏览器支持。

2、检测方法

下面的方法可以使用脚本判断浏览器是否支持某一个CSS3属性:

/** 
* 判断浏览器是否支持某一个CSS3属性 
* @param {String} 属性名称 
* @return {Boolean} true/false 
* @version 1.0 
* @author ydr.me 
* 2014年4月4日14:47:19 
*/ 

function supportCss3(style) { 
var prefix = ['webkit', 'Moz', 'ms', 'o'], 
i, 
humpString = [], 
htmlStyle = document.documentElement.style, 
_toHumb = function (string) { 
return string.replace(/-(\w)/g, function ($0, $1) { 
return $1.toUpperCase(); 
}); 
}; 

for (i in prefix) 
humpString.push(_toHumb(prefix[i] + '-' + style)); 

humpString.push(_toHumb(style)); 

for (i in humpString) 
if (humpString[i] in htmlStyle) return true; 

return false; 
}
Copy after login

3、使用方法

alert(supportCss3('animation-play-state'));
