Easy URL Query String Manipulation Plugin - jQuery querystring.js

Query strings (also known as URL query parameters) are used in multiple places throughout websites and web applications. They allow adding extra information to the end of a URL(request), and can be used for many different things, such as passing state between requests within your application or even for user identification.

In this article I'll introduce you to a tiny jQuery plugin that you can use to easily dynamically add/modify/delete/get query strings using plain JavaScript. It supports standard query strings, non-standard slash query strings, and hash strings.

How to use it:

1. To get started, include the jquery.querystring.min.js script after jQuery library.

<script src="/path/to/cdn/jquery.slim.min.js"></script>
<script src="/path/to/cdn/jquery.querystring.min.js"></script>

2. Create a new instance of the queryString

// basic
var instance = new $.queryString();

// OR
var instance = new $.queryString('jqueryscript');
=> /path/to/jqueryscript?key=value

// OR
var instance = $.queryString("https://www.jqueryscript.net");
=> https://www.jqueryscript.net/?key=value

3. Set query/hash string parameters.

// set standard parameters
instance.params.hello = "world";
instance.params["dashed-key"] = "dashed-value";
instance.params["encoded-key"] = "{(encoded&+=|value)}";

// set hash values
instance.hash.page = 1;
instance.hash.row = 42;

4. Get all query/hash string parameters.

// get standard parameters
var value = instance.params[key];
console.info(key, value);

// get hash values
var value = instance.hash[key];
console.info(key, value);

5. Delete all query/hash string parameters.

// delete standard parameters
delete instance.params.key;

// delete hash values
delete instance.hash.key;

6. Available options.

var instance = new $.queryString(url, {

    // encode query string
    encode: true,

    // standard, slash
    format: "standard", 

    // callback
    encodeCallback: encode,
