// 1. 因为要弹出四个输入框,所以利用循环弹出四次
let arr = []
for (let i = 1; i <= 4; i++) {
arr.push(prompt(`请输入第${i}个数据`)) //将每次输入的数据追加到数组中
}
// 2.外面的box直接打印,通过for循环打印box里面的柱型图 (渲染页面)
// box 头部直接打印
document.write(`<div class="box">`)
// box里面的柱形图区域通过渲染打印
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>
</div>
`)
}
// box尾部直接打印
document.write(`</div>`)
