var obj = window.getComputedStyle(box); console.log( window.getComputedStyle(box) ); console.log(obj.width);
通过点按钮使方块宽度增加：
document.querySelector("button").onclick = function(){
var timer = setInterval(function(){
// 获取宽
var obj = window.getComputedStyle(box);
var w = obj.width
w = parseInt(w)
w += 10
if(w>=700){
clearInterval(timer)
}
box.style.width = w + "px"
// console.log(w);
},50)
}
注意：不要拿颜色值判断
var box = document.getElementsByTagName(‘div‘) box = box[0] console.log(getComputedStyle(box).width); 在ie中使用： 标签.currentStlye console.log(box.currentStyle.height);
function getStyle(ele,attr){ if(window.getComputedStyle){ return getComputedStyle(ele)[attr] }else{ return ele.currentStyle[attr] } } var h = getStyle(box,‘background-color‘) console.log(h); var w = getStyle(box,‘width‘) console.log(w);
