transitionEnd设计

 

   收录一段动画end的设计：

 

function transitionEnd(){
 
     var el = document.createElement("div");

     var transEndEventNames = {
           'WebkitTransition' : 'webkitTransitionEnd',
           'MozTransition' : 'transitionend',
           'OTransition' : 'oTransitionEnd otransitionend',
           'transition' : 'transitionend'
     };

    for(var name in transEndEventNames){
         if(el.style[name] !== undefined){
               return {
                     end : transEndEventNames[name]
               };
         }
    }

}
