js中最最常用的函数封装，方便调用

事件委托的封装

function eveEnt(child,cb){
		return function(eve){
			var e = eve || window.event;
			var mubiaoEle = e.target || e.srcElement;
			for(var i = 0;i<child.length;i++){
				if(child[i]==mubiaoEle){
					cb.bind(mubiaoEle)();
				}
			}
		}
	}

事件监听式绑定事件

function addEvent(ele,type,cb){
		if(ele.addEventListener){
			ele.addEventListener(type,cb,false);
		}else{
			ele.attachEvent("on"+type,cb)
		}
	}

阻止事件冒泡的封装

function stopBubble(eve){ 
   if(event.stopPropagation){
   eve.stopPropagation();
   }else{ eve.cancelBubble=true; }
 }

非行内样式的兼容

function getStyle(ele,attr){
		if(ele.currentStyle){
			return ele.currentStyle[attr];
		}else{
			return getComputedStyle(ele,false)[attr];
		}
	}

缓冲运动的封装

function move(ele,attr,target){
		clearInterval(ele.t);
		ele.t=setInterval(()=>{
			var s=getStyle(ele,attr);
			var iNow=parseInt(s);
			let speed=(target-iNow)/10;
			speed=speed<0? Math.floor(speed) :Math.ceil(speed);
			if(target==iNow){
				clearInterval(ele.t);
			}else{
				ele.style[attr]=iNow+speed+"px";
			}
		},30);
	}

随机数的封装

function random(min, max) {
    return Math.round(Math.random()*(max - min)+min);
 }

后期还会更新，敬请期待哦！！！
