Synopsis

Query Passthru is a jQuery plugin that persists URL query parameters throughout your page(s). It supports overwriting query parameters already on the link and passing in additional query parameters to append.

Usage

Include the script query-passthru.min.js after jQuery.

$("a").passthru();

If the above code is on a page whose URL is (for example) https://myawesomesite.com/contact-us/?utm_source=direct&utm_campaign=adwords, all of the a tags (with an href attribute) will get ?utm_source=direct&utm_campaign=adwords appended.

Options

$("a").passthru({options}, {forcedParameters});

Currently the only option is overwrite: true/false (default true). When true, if a link is found containing a matching parameter key, the link's existing key/value will be overwritten with the value found in the document URL. If set to false, any existing parameters will not be overwritten by any matching keys in the URL.

forcedParameters is an optional object that will append additional key/value pairs to the resulting href attribute. These will always overwrite any existing parameters that match the given key(s).

Installation

You can install query-passthru with npm:

npm install --save query-passthru
