Parameter passed through URL

Get URL parameters

ASP

    prodid = Request.QueryString ("prodid")

ASP.NET (C#)

      string Name = Request.QueryString["Name"];
      string Age = Request.QueryString["Age"];
      Response.Write(Age); 

JSP

	String hist_list = "0";
	if (request.getQueryString()!=null)
	{
		hist_list = request.getParameter("hist").trim();
		if (hist_list==null) 
			hist_list="0";
	}

JavaScript

	A useful little JavaScript function which will get a URL parameter and return it to you. 
	For example if the current URL is "...?opendocument&id=testid" then calling 
	getURLParam("id") will return "testid".
	
	function getURLParam(strParamName){
	  var strReturn = "";
	  var strHref = window.location.href;
	  if ( strHref.indexOf("?") > -1 ){
	    var strQueryString = strHref.substr(strHref.indexOf("?")).toLowerCase();
	    var aQueryString = strQueryString.split("&");
	    for ( var iParam = 0; iParam < aQueryString.length; iParam++ )
	    {
	      if (aQueryString[iParam].indexOf(strParamName + "=") > -1 )
	      {
	        var aParam = aQueryString[iParam].split("=");
	        strReturn = aParam[1];
	        break;
	      }
	    }
	  }
	  return strReturn;
	}
