代碼如下：span標簽里的數字不會顯示<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html xmlns="http://www.w3.org/1999/xhtml"><head><meta http-equiv="Content-Type" content="text/html; charset=utf-8" /><title>無標題文檔</title><script type="text/javascript">var time=5;function timecount(){ document.getElementById("js")=time; time--; i=setTimeout(timecount,1000); if(time==0){ clearTimeout(i); window.open('http://wwww.baidu.com'); }}function goback(){ window.history.go(-1);}timecount();</script></head><body><p>操作成功</p><br /><span id="js"></span>秒后跳回指定頁面<a href="javascript:goback()">返回之前頁面</a></body></html>
這段代碼為什么無法執行
