使用JavaScript實(shí)現(xiàn)頁(yè)面定時(shí)跳轉(zhuǎn)并顯示倒計(jì)時(shí)
1.創(chuàng)建一個(gè)就簡(jiǎn)單的頁(yè)面
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>頁(yè)面定時(shí)自動(dòng)跳轉(zhuǎn)并顯示倒計(jì)時(shí)</title>
</head>
<body>
<h1>自動(dòng)跳轉(zhuǎn)：<span id="wait">4</span></h1>
</body>
</html>
2.js函數(shù)
/**
  * 定時(shí)跳轉(zhuǎn)
  * href 要跳轉(zhuǎn)的鏈接
  * elemId 顯示時(shí)間元素
  */

function TimeLocation(href,elemId){
var elem = document.getElementById(elemId);
var interval = setInterval(function(){
        var time = --elem.innerHTML;
  if(time <= 0) {
   location.href = href;
   clearInterval(interval);
  }
},1000);
}
3.調(diào)用
window.onload=function(){
TimeLocation('localhost','wait');
}
