// same thing:
// first = test["SSN"]; // returns 1

var parameters = window.location.search;
// returns query string after '?', which can be empty
if (!parameters) return result;
parameters = parameters[1].split("&");
for (var parameter in parameters) {
var keyValue = parameters[parameter].split("=");
result[keyValue[0]] = decodeURIComponent(keyValue[1]);

Solution 1

I think it's because you have defined the method after your method call.
Try this :-

$(function parseQuery(url)
{
    var result = {};
    var parameters = window.location.search;
    // returns query string after '?', which can be empty
    if (!parameters) return result;
    parameters = parameters[1].split("&");
    for (var parameter in parameters) {
        var keyValue = parameters[parameter].split("=");
        result[keyValue[0]] = decodeURIComponent(keyValue[1]);
    }
    return result;
});

var test = parseQuery(window.location.href);
var SSN = test.SSN; // returns 1
console.log(SSN);
// var second = text.second; // returns 2
// same thing:
// first = test["SSN"]; // returns 1
// second = text["second"]; // returns 2

This is giving the perfect result for me.
Hope this one will help you :).

UPDATE

$(function () {
    //Set the hubs URL for the connection
    function parseQuery(url) {
        var result = {};
        var parameters = window.location.search;
        
        // returns query string after '?', which can be empty
        if (!parameters) return result;
            
        parameters = parameters[1].split("&");
            
        for (var parameter in parameters) {
            var keyValue = parameters[parameter].split("=");
            result[keyValue[0]] = decodeURIComponent(keyValue[1]);
            if (result[keyValue[0]] == null)
                alert("The parameter is null");

            else 
                alert(resultkeyValue[1]);
        }

        return result;
    };

    var test = parseQuery(window.location.href);
    var SSN = test;
});

Remove $ from the method function parseQuery(url) { and try again.

This is the code im using to pass a ssn value and get it from the url and display the passed vale using if (result[keyValue[0]] == null)

alert("The parameter is null");

else alert(resultkeyValue[1]);

this above code under the below mentioned function

$(function parseQuery(url) {
var result = {};
var parameters = window.location.search;
// returns query string after '?', which can be empty
if (!parameters) return result;
parameters = parameters[1].split("&");
for (var parameter in parameters) {
var keyValue = parameters[parameter].split("=");
result[keyValue[0]] = decodeURIComponent(keyValue[1]);
if (result[keyValue[0]] == null)

alert("The parameter is null");

else alert(resultkeyValue[1]);

}
return result;
});
