今天,同事问我一个问题,如何返回调用页而不是固定的页面。经过查阅帮助,得到如下解决方式:
<html xmlns="http://www.w3.org/TR/REC-html40" xmlns:v="urn:schemas-microsoft-com:vml"
 xmlns:o="urn:schemas-microsoft-com:office:office">
 <head>
  <meta http-equiv="Content-Language" content="zh-cn">
  <title>实验室信息管理系统</title>
  <meta http-equiv="Content-Type" content="text/html; charset=gb2312">
  <script language="JavaScript" type="text/JavaScript">
<!--
function MM_reloadPage(init) {  //reloads the window if Nav4 resized
  if (init==true) with (navigator) {if ((appName=="Netscape")&&(parseInt(appVersion)==4)) {
    document.MM_pgW=innerWidth; document.MM_pgH=innerHeight; onresize=MM_reloadPage; }}
  else if (innerWidth!=document.MM_pgW || innerHeight!=document.MM_pgH) location.reload();
}
MM_reloadPage(true);
//-->
</script>
  <style type="text/css"> img{cursor: hand }

  </div>
 </body>
 <script language="javascript">
 <!--
 var back = document.getElementById("back");
 if (document.referrer.length == 0)
  back.href = "index.htm"
 else
  back.href = document.referrer;
 -->
 </script>

 
</html>

注意红色部分。需要说明的是:
1、首先判断document.referrer是否为空,如果为空,则页面访问是通过直接录入而来的,页面导向首页,否则导向引用页面。
2、代码需要放在页面后面,这样才能够访问到back连接元素。
3、需要在Web服务器上测试,在本地浏览时,无论何时referrer都为空。我也是多次试验才发现的。
补充:
刚看到一个帖子,很好。可以如下解决:
<a target="_parent" id="back"><span style="text-decoration: none">返回上一级</span></a>改为
<a target="_parent" id="back" href=javascript:history.back()><span style="text-decoration: none">返回上一级</span></a>
后来:发现它需要在C/S程序中调用HTM页面,通过IEBrowser控件,又通过Cookie方式进行了实现
基本原理是在包含这个连接的页面载入时,写入该页面连接到Cookie中,返回时读取写入的Cookie进行返回。
