將一下代碼放入js中：

function prefix() {  
            var div = document.createElement('div');  
            var cssText = '-webkit-transition:all .1s; -moz-transition:all .1s; -o-transition:all .1s; -ms-transition:all .1s; transition:all .1s;';  
            div.style.cssText = cssText;  
            var style = div.style;  
            if (style.webkitTransition) {  
                return '-webkit-';  
            }  
            if (style.MozTransition) {  
                return '-moz-';  
            }  
            if (style.oTransition) {  
                return '-o-';  
            }  
            if (style.msTransition) {  
                return '-ms-';  
            }  
            return '';  
        }  

在需要的地方賦值，或直接調(diào)用：

var cssPrefix = prefix();  
alert(cssPrefix);
