setTimeout用法
请先看下代码:
ccc.jsp
<%@ page contentType= "text/html;charset=GBK "%>
<html>
<head>
<script language= "javascript ">
<!--
var v_time_num=3;
var ss=v_time_num;
function lk_Log(){
document.form1.t1.value = ss;
if(ss==0 ){
ss=v_time_num; document.getElementById( "log_iframe ").src= "ddd.jsp " ; log_iframe.log_form.submit();
}
ss--;
setTimeout( "lk_Log() ", 1000);
}
//-->
</script>
</head>
<body>
<form name= "form1 " >
<input type= "text " name= "t1 " value= " " />
</form>
<iframe id= "log_iframe " name= "log_iframe " src= "ddd.jsp " style= "display:none " > </iframe>
</body>
<script> window.onload = lk_Log; </script>
</html>
ddd.jsp
<%@ page contentType= "text/html;charset=GBK "%>
<html>
<head>
</head>
<%
System.out.println( "dddddddddddddddddddddddddddddd ");
out.println( " <script> location.href= 'ccc.jsp '; <script> ");
%>
</html>
我想每次在ccc.jsp页面计时结束后，跳转到ddd.jsp，打印完了再回来，重新开始计时，现在跳到ddd.jsp，没有办法回来继续计时了，请指教下。谢谢！
