This javascript function grabs any query parameters and stores them in an array

Query Parameters

var getQueryParams = function () {
    var params = [];
    var query = window.location.search;
    query = query.slice(1, query.length);
    var nv = query.split('&');
    for (var i = 0; i < nv.length; i++) {
        var q = nv[i].split('=');
        params[q[0]] = q[1];
    }
    return params;
};

//-- Example -- 
//www.example.com?product=1234&type=Shirt

var parameters = getQueryParams(); //Calls the function and stores values into variable 'parameters'
var productNumber = parameters.product; // 1234
var productType = parameters.type; // Shirt
