<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Document</title> <style> body { text-align: center; font: 700 30px/1.5 arial; } </style> </head> <body> <script> var oBody = document.body; var i = 0; document.onreadystatechange = subSomething; function subSomething() { if (document.readyState == "complete") { setInterval(function sum() { oBody.innerHTML = ++i; }, 1000); } } </script> </body> </html>
.onreadystatechange 檢測頁面狀態
.readtState = "complete";表示頁面載入完成
