Question

Do you know a fast and simple way to encode a Javascript Object into a string that I can pass via a GET Request?

No jQuery, no

Refer from the answer @user187291, add "isArray" as parameter to make the json nested array to be converted.

data : {
                    staffId : "00000001",
                    Detail : [ {
                        "identityId" : "123456"
                    }, {
                        "identityId" : "654321"
                    } ],

                }

To make the result :

staffId=00000001&Detail[0].identityId=123456&Detail[1].identityId=654321

serialize = function(obj, prefix, isArray) {
        var str = [],p = 0;
        for (p in obj) {
            if (obj.hasOwnProperty(p)) {
                var k, v;
                if (isArray)
                    k = prefix ? prefix + "[" + p + "]" : p, v = obj[p];
                else
                    k = prefix ? prefix + "." + p + "" : p, v = obj[p];

                if (v !== null && typeof v === "object") {
                    if (Array.isArray(v)) {
                        serialize(v, k, true);
                    } else {
                        serialize(v, k, false);
                    }
                } else {
                    var query = k + "=" + v;
                    str.push(query);
                }
            }
        }
        return str.join("&");
    };

    serialize(data, "prefix", false);
