Answer 1

You should try this

In JavaScript you can get values from URL of any param using a function that in below.

$(document).ready(function () {
    var getUrlParameter = function getUrlParameter(sParam) {
        var sPageURL = window.location.search.substring(1),
                sURLVariables = sPageURL.split('&'),
                sParameterName,
                i;
        for (i = 0; i < sURLVariables.length; i++) {
            sParameterName = sURLVariables[i].split('=');
            if (sParameterName[0] === sParam) {
                return sParameterName[1] === undefined ? true : decodeURIComponent(sParameterName[1]);
            }
        }
    };

    var id = getUrlParameter('id');
});

I know it was long code but using this method you can get values of any param.

var id = getUrlParameter('id');

var anyparam = getUrlParameter('param_name');
