<script>
//1.利用循环弹出四次输入框，会得到四个数据，放到数组里面
let arr = []
for(let i = 1;i<=4;i++)
{
arr.push(prompt(`请输入第${i}季度的数据`))
}
//console.log(arr)
//注意我们渲染的是柱子
document.write(`<div class ="box">`) //打印头部
//循环四个柱子
for(let i = 0;i<arr.length;i++)
{
document.write(`
<div style="height: ${arr[i]}px;">
<span>${arr[i]}</span>
<h4>第${i+1}季度</h4>
