JS多物体任意值链式缓冲运动_javascript技巧



代码如下:











var odiv=document.getElementById('odiv');
odiv.onmouseover=function(){
move(this,'width',500,function(){
move(odiv,'left',300,function(){
move(odiv,'height',500,function(){
move(odiv,'borderWidth',10)
})
})});}
function move(obj,arr,target,fn){
var dt=null,speed=0,ol=0;
clearInterval(dt);
dt=setInterval(function(){
ol=parseInt(obj.style[arr]);
if(ol==target){
clearInterval(dt);
if(fn) fn();
}else{
speed=(target-ol)/8;
speed>0?speed=Math.ceil(speed):speed=Math.floor(speed);
obj.style[arr]=ol+speed+"px";
}
},30);
}
