//创建颜色数组
var colour = ["red", "yellow", "orange", "blue", "purple", "green","#cdee","#feda","ccc","#eda","#639","#33f","#f38","#ca0"]
for (j = 1; j <= 50; j++) {
var lis = document.createElement("li");//创建带数字的li
lis.innerHTML = j;
lis.style.height = Math.random() * 40 + 30 + "px";//获取随机高度，最小高度为30px
lis.style.backgroundColor = colour[parseInt(Math.random() * colour.length-1)];//获取随机颜色
for (var i = 0; i < boxs.length; i++) {
console.log(boxs[i].clientHeight);
// offsetHeight获得元素高度的 数字
if (boxs[i].offsetHeight < boxs[min].offsetHeight) {
min = i;//获取高度最小数组元素的序号
}
}
boxs[min].appendChild(lis)//把li添加到最短ol里
}
function reloadPage() {
location.reload();//刷新
}
