[asp.net] 获取网页访问来路的几种方法
一、C#代码一
string url = Request["referer"];
Response.Write("alert('" url "')");
Response.End();
可以使用如下的四种中的其中一种
HttpRequest.UrlReferrer
Request.UrlReferrer.AbsolutePath
HttpContext.Current.Request.Url.ToString()
Request.ServerVariables["Http_Referer"]
获得上个页面链接地址
二、HTML code
<script >
var url = 'js.aspx?referer=' encodeURIComponent(document.referrer);
document.write(' <' 'script type="text/java script" src="' url '" > <' '/script >');
</script >
三、xmlhttp代码
var objXMLHTTP=new ActiveXObject( "MICROSOFT.XMLHTTP ");
var url = "http://www.dzwebs.net/ " "se.asp?temp= " name1.value " &id= " name2.value " &len= " name3.value;
objXMLHTTP.open( "GET ",url,false);
objXMLHTTP.send();
var strReturn=objXMLHTTP.ResponseText;
if (strReturn== "error ")
{alert( "there is error occurred! ");
else
//do next
