jsp are Java Server Pages - and since javascript doesn't have anything to do with Java...

I don't know enough about Java Server Pages to ascertain wether the parameters passed via GET (ie. ?something=something after the url) are turned into variables, but somehow I doubt it. It's a lot more likely they're stored into an associative array or such.

You can get the parameters (GET or POST) in the JSP (Java code) using the following:

code:

<%

String var = request.getParameter("varient");

....

%>

You can parse only GET URLs in the client side code (window.location.href).
Try the following code to parse URL (I'm sure you can improve it)

code:

//<protocol>://<user>:<password>@<server>:<port>/<URI>?<param1>=<val1>&<param2>=<val2>&<param3>=<val3>

var _COMP_ERR = "***ERROR***"

function parseURL(url){

    // Build the return URL object.

    var oUrl = new Object();

    oUrl.uri = "";

    oUrl.port = 80;

    oUrl.protocol = "http";

    oUrl.server = "";

    oUrl.user = "";

    oUrl.password = "";

    oUrl.parameters = new Array();



    // Get the protocol (if any) <protocol>://...

    var tmp = trim(url);

    var i = tmp.indexOf("://");

    if(i>-1){

        oUrl.protocol = tmp.substring(0, i).toLowerCase();

        tmp = tmp.substring(i + 3, tmp.length);

    }



    // get the URI <user>:<password>@<server>:<port>/<URI>?....

    i = tmp.indexOf("?");

    var uri = tmp;

    if(i>-1){

        uri = tmp.substring(0, i);

        tmp = tmp.substring(i + 1, tmp.length);

    } else {

		tmp = "";

    }

    // get authentication user & password (if any) <user>:<password>@

    i = uri.indexOf("@");

    var auth = "";

    if(i>-1){

        auth = uri.substring(0, i);

        uri = uri.substring(i + 1, uri.length);



        i = auth.indexOf(":");

        oUrl.user = auth;

        if(i>-1){

            oUrl.user = auth.substring(0, i);

            oUrl.password = auth.substring(i + 1, auth.length);

        }

    }

    // get the server name and port <server>:<port>/...

    i = uri.indexOf("/");

    var server = uri;

    if(i>-1){

        server = uri.substring(0, i);

        try {

            oUrl.uri = decodeURI(uri.substring(i + 1, uri.length));

        }catch(e){

            oUrl.uri = _COMP_ERR;

        }

    }

    oUrl.server = server;

    i = server.indexOf(":");

    if(i>-1){

        oUrl.server = server.substring(0, i);

        oUrl.port = server.substring(i + 1, server.length);

	    try {

			oUrl.port = parseInt(oUrl.port);

		}catch(e){

			oUrl.port = _COMP_ERR;

		}                

    }



    // get the parameters ?<param1>=<val1>&<param2>=<val2>&<param3>=<val3>...

    while(tmp.length>0){

        var oParam = new Object();

        var param = "";

        i = tmp.indexOf("&");

        if(i>-1){

            param = tmp.substring(0, i);

            tmp = tmp.substring(i + 1, tmp.length);

        } else {

            param = tmp;

            tmp = "";

        }



        i = param.indexOf("=");

        if(i>-1){

            oParam.key = param.substring(0, i);

		    try {

				oParam.value = decodeURIComponent(param.substring(i + 1, param.length));

			}catch(e){

				oParam.value = _COMP_ERR;

			}

        } else {

            oParam.key = param;

            oParam.value = "";

        }

        if(oParam.key.length > 0){

            oUrl.parameters[oUrl.parameters.length] = oParam;

        }

    }



    return oUrl;

}
