autocomplete-rails.js

/*
* Unobtrusive autocomplete
*
* To use it, you just have to include the HTML attribute autocomplete
* with the autocomplete URL as the value
*
*   Example:
*       <input type="text" data-autocomplete="/url/to/autocomplete">
*
* Optionally, you can use a jQuery selector to specify a field that can
* be updated with the element id whenever you find a matching value
*
*   Example:
*       <input type="text" data-autocomplete="/url/to/autocomplete" data-id-element="#id_field">
