JS method to determine whether the browser supports a certain CSS3 attribute_javascript skills
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; }
3、使用方法
alert(supportCss3('animation-play-state'));
